3cdc2661d2 Dive media: add media to closest dive
Currently, when selecting "Load media files even if time does not
match the dive time", the media are added to *all* selected dives.
Instead add it to the closest dive.

This seems like the less surprising behavior. Of course now if the
user really wants to add a media file to multiple dives, they will
have to do it manually.

To avoid a messy interface, this is solved by moving the iterate-
over-selected-dives loop to the core. Thus, a helper-function can
be made local to its translation unit.

6bf4120dbb Core: replace tripflag by notrip boolean
The only remaining use of the tripflag was to mark dives that
were removed explicitly from a trip, i.e. shouldn't be autogrouped.
Therefore replace the enum by a simple boolean.

Currently, there is no way of unsetting the notrip flag. But this
shouldn't result in a user-visible change.

3b9e0b5931 Core: remove ASSIGNED_TRIP trip flag
The distinction between ASSIGNED_TRIP and IN_TRIP was used to
prefer non-autogenerated trips on merging of dives. But owing
to bit rot this seem to have worked only partially anyway:
The IN_TRIP field was set in create_and_hookup_trip_from_dive()
and immediately overwritten in add_dive_to_trip() called
in the next line.

Instead, use the trip->autogen flag to check for priority and
remove the ASSIGNED_TRIP flag alltogether.

sanitize_cylinder_type(), which is indirectly called from fixup_dive(),
had ft^3 -> mliter conversion code, which was executed on the
condition "xml_parsing_units.volume == CUFT".

But nowhere in the code base would xml_parsing_units.volume ever be

Dive importing is now performed via a distinct table which is
merged into the main dive table. Thus, it is known which of the
dive is new and which is old. This information can now be
implicitely encoded in the parameter-position of merge_dive()

dive table. In the future, we will have to delete dives outside
of this table (e.g. for undo). Therefore, split out the free_dive()

21b1550739 Dive media: on import read metadata only once
On import of dive media, the timestamp is read from the
metadata to check if the image belongs to the selected dives.
The pictures are then listed in a dialog.

Currently, the metadata is read twice if images are outside
of a dive: once in picture_check_valid() and if it turns
out that the picture is not valid again in picture_get_time()
to display the proper timestamp.

Even though metadata-extraction is reasonably fast, this is
a bit of an embarrassment.

Instead, read the timestamps only once in the constructor of
the dialog and from then on only used these timestamps. Keep
the timestamps in a QVector. Rename the picture_check_valid()
function to picture_check_valid_time() and pass a timestamp
instead of a filename.

92deb7aa70 Cleanup: make surface sample in merge_one_sample() non-static
The merge_one_sample() function adds a sample to the destination
dive if dives are merged. For long periods between samples at surface
depths, it adds a surface interval.

To decrease the number of global objects, make the sample structure
non-static. Of course, initialization of an on-stack structure is
slower. Therefore move it into the corresponding if. Thus, the
structure will be initialized only once per surface-interval.

6e4a253896 Profile: fix SAC calculation for air dives
Commit f5b11daffd changed gasmix
arguments and return values to be passed by value instead of
using pointers.

Notably, get_gasmix() is fed a default-value and returns a
new value. In the old code, NULL was passed in in a first
loop iteration and non-NULL was always returned in the first
iteration. Thus, an equality comparison of passed-in an
returned gasmix would always fail in the first loop iteration.

The new code passed in air as default. Now if air was also
returned, then the matching gases were not calculated in
calculate_sac(). To revert to the old behavior, pass in
an invalid gasmix.

Moreover, give names to the invalid and air gasmixes.

605e1e19ed Cleanup: const-ify functions taking pointers to events
This is another entry in the series to make more things
"const-clean" with the ultimate goal of merge_dive() take

This concerns functions taking pointers to events and
the fallout from making these const.

The somewhat debatable part of this commit might be
that get_next_event() is split in a two distinct
(const and non-const) versions with different names,
since C doesn't allow overloading. The linker should
recognize that these functions are identical and remove
one of them.

360f07e453 Cleanup: pass gasmix by value
In a previous commit, the get_gasmix_* functions were changed to
return by value. For consistency, also pass gasmix by value.

Note that on common 64-bit platforms struct gasmix is the size
of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the
same space on the stack. On 32-bit platforms, the stack use
is probably doubled, but in return a dereference is avoided.

Supporting arbitrary gas-mixes (H2, Ar, ...) will be such an
invasive change that going back to pointers is probably the
least of our worries.

This commit is a step in const-ifying input parameters (passing
by value is the ultimate way of signaling that the input parameter
will not be changed [unless there are references to said parameter]).

f5b11daffd Cleanup: return gasmix by value
Currently, get_gasmix_from_event() and get_gasmix() return pointers
to either static or to (possibly changing) dive data. This seems like
a dangerous practice and the returned data should be used immediately.

Instead, return the gasmix by value. This is in preparation of
const-ifying input parameters of a number of core functions, which
will ultimately let the merge() function take const-arguments in
preparation of undo of dive-merging.

On common 64-bit systems gasmix (two "int"s) is the size of a pointer
and can be returned in a register.

On 32-bit systems a pointer to the struct to be filled out will be
passed.

Since get_gasmix() now returns a value, the first invocation is
tested by a NULL-initialized "struct event *". Document this in
a comment.

2c6b1a99af Cleanup: simplify dive_getUniqID()
dive_getUniqID() is used to create unique dive ids, which are
stable during application lifetime. It was passed a dive, checked
that the id was not set (if it was that it is know to the application)
and set a new id (in contradiction to its name!) if it hadn't any.

There were three callers:

alloc_dive(): called the function on a zeroed dive struct.
fixup_dive(): called the function only if the dive had a 0 id.
MainWindow::setupForAddAndPlan(): called the function on a zeroed dive
struct.

Thus, in all three callers the id is guaranteed to be zero and
the whole keeping-track-of-ids logic is moot. Remove the logic,
don't pass a dive struct to dive_getUniqID() and move the function
to the C-backend.

And when we look for "are these the exact same dives", we should check

computer time matches, so that we don't consider two parts of a dive

3209b490dd Use proper sample pointer when deciding to split dives
The dive splitting was completely wrong, because we checked the time of
the previous sample by doing

	sample[i - 1].time.seconds

which is entirely wrong.  The 'sample' variable is the *current* sample,
so the time of the previous sample is simply

	sample[-1].time.seconds

Alternatively, we could have started from the first sample, and done

	dc->sample[i - 1].time.seconds

but mixing the two concepts up just gets you a random sample pointer
that is likely not a valid sample at all, and obviously does not have
the right time at all.

As a result, dive splitting was pretty much random.  Sometimes it worked
purely by mistake, because the rest of the logic was right (ie we _had_
found the right point where we reached the surface in the dive etc, the
"previous sample time" was simply used to decide if the surface interval
was sufficient to split the dive up).

2e8f506635 Dive pictures: remove cache_picture() call in dive_add_picture()
When adding a picture to a dive, cache_picture() was called, which
calculated the hash of the picture in a background-thread.

This made tests occasionally fail, because the tests depended on
the filename-to-localfilename being overwritten in a call running
in a different thread. Depending on which thread finished first,
the test succeeded or failed.

The easiest way to circumvent this problem is to remove the cache_picture()
call. The hash will be calculated anyway with the thumbnails. And
the only function of the hash is the "find moved images" function. Which
is not an issue here, because the user just loaded the images from
disk.

9c24d6bef8 Fix bug for CCR dive bailout
Under some conditions get_current_divemode() (in dive.c) returns an
erroneous divemode. This happens when there are several events at

27a0542220 Implement bailout outside of the dive planner
This is the second step for implementing bailout. The indirect
calls to fill_pressures through add_segment() (in deco.c) are
addressed. Bailout is now fully implemented in the dive log but
not in the dive planner.
1) The parameters to add_segment() are changed to take a
   divemode as the second last parameter, and not a *dive.
2) Call to add_segment() in profile.c and in divelist.c are
   adapted. In divelist.c some calls to add_segment were left
   using dc-> divemode instead of possible bailout. This appears
   tp be the most appropriate route.
3) The functions get_divemode_from_time() and get_next_divemodechange()
   in dive.c have had some small changes.
4) The calls to get_segment(0 in planner.c were changed to reflect
   the new parameter list, but not updated to reflect bailout. This
   is the next step.

cf377beb2e Incorporate bailout events in CCR & PSCR gas calculations.
This is a first step to interpret bailout events.
1) The event structures have a new attribute: divemode.
   Currently interpreted dive modes are OC, CCR, PSCR.
2) When doing fill_pressures(), the calculation is aware
   of divemode. When divemode is OC (==bailout), then
   the appropriate calculations of gas pressures are done.
3) Two new functions get_next_divemodechange() and
   get_divemode_at_time() are created to find divemode
   changes in the events linked list and to determine
   the dive mode at any point during the dive.
4) fill_pressures gets a small amendment to facilitate
   the correct calculations, depending on divemode.
The cases where fill_pressures() is used *outside the planner*
are changed. The result is that, for dives with bailout, the
correct gas pressures are shown on the dive profile. The
deco for bailout dives is not yet correct. This is the
next step.

920ff15f71 Planner: don't return static data in fake_dc()
fake_dc() used to return a statically allocated dc with statically
allocated samples. This is of course a questionable practice in
the light of multi-threading / resource ownership. Once these
problems were recognized, the parameter "alloc" was added. If set
to true, the function would still return a statically allocated
dc, but heap-allocated samples, which could then be copied in
a different dc.

All in all an ownership nightmare and a recipie for disaster.
The returned static dc was only used as a pointer to the samples
anyway. There are four callers of fake_dc() and they all have access
to a dc-structure without samples. Therefore, change the semantics
of fake_dc() to fill out the passed in dc. If the caller does
not care about the samples, it can simply reset the sample number
to zero after work.

df1bd0015a Calculate momentary SAC rates with the right gases
The momentary SAC rate got broken by the multiple ressure handling too,
and always used just the first cylinder.

This uses the new "get_gasmix()" helper to see what you're breathing,
and will do the SAC rate over all the cylinders that contain that gas.
So it should now DTRT even for sidemount diving (assuming you had the
same gas in the sidemount cylinders).

NOTE! We could just do the SAC rate over *all* the gases you have
pressures for, and maybe that's the right thing to do.  The ones you are
not breating from shouldn't have their pressure change.  But maybe some
people add their drysuit argon gas to the gas list?

So this may need more work, but it's a step in the right direction.

e1b880f444 Profile support for multiple concurrent pressure sensors
This finally handles multiple cylinder pressures, both overlapping and
consecutive, and it seems to work on the nasty cases I've thrown at it.

Want to just track five different cylinders all at once, without any
pesky gas switch events? Sure, you can do that.  It will show five
different gas pressures for your five cylinders, and they will go down
as you breathe down the cylinders.

I obviously don't have any real data for that case, but I do have a test
file with five actual cylinders that all have samples over the whole
course of the dive.  The end result looks messy as hell, but what did
you expect?

HOWEVER.

The only way to do this sanely was

 - actually make the "struct plot_info" have all the cylinder pressures
   (so no "sensor index and pressure" - every cylinder has a pressure for
   every plot info entry)

   This obviously makes the plot_info much bigger. We used to have
   MAX_CYLINDERS be a fairly generous 8, which seems sane. The planning
   code made that 8 be 20. That seems questionable. But whatever.

   The good news is that the plot-info should hopefully get freed, and
   only be allocated one dive at a time, so the fact that it is big and
   nasty shouldn't be a scaling issue, though.

 - the "populate_pressure_information()" function had to be rewritten
   quite a bit. The good news is that it's actually simpler now, although
   I would not go so far as to really call it simple. It's still
   complicated and suble, but now it explicitly just does one cylinder at
   a time.

   It *used* to have this insanely complicated "keep track of the pressure
   ranges for every cylinder at once". I just couldn't stand that model
   and keep my sanity, so it now just tracks one cylinder at a time, and
   doesn't have an array of live data, instead the caller will just call
   it for each cylinder.

 - get rid of some of our hackier stuff, like the code that populates the
   plot_info data code with the currently selected cylinder number, and
   clears out any other pressures. That obviously does *not* work when you
   may not have a single primary cylinder any more.

Now, the above sounds like all good things. Yeah, it mostly is.

BUT.

There's a few big downsides from the above:

 - there's no sane way to do this as a series of small changes.

   The change to make the plot_info take an array of cylinder pressures
   rather than the sensor+pressure model really isn't amenable to "fix up
   one use at a time". When you switch over to the new data structure
   model, you have to switch over to the new way of populating the
   pressure ranges. The two just go hand in hand.

 - Some of our code *depended* on the "sensor+pressure" model. I fixed all
   the ones I could sanely fix. There was one particular case that I just
   couldn't sanely fix, and I didn't care enough about it to do something
   insane.

   So the only _known_ breakage is the "TankItem" profile widget. That's
   the bar at the bottom of the profile that shows which cylinder is in
   use right now. You'd think that would be trivial to fix up, and yes it
   would be - I could just use the regular model of

     firstcyl = explicit_first_cylinder(dive, dc)
     .. then iterate over the gas change events to see the others ..

   but the problem with the "TankItem" widget is that it does its own
   model, and it has thrown away the dive and the dive computer
   information. It just doesn't even know. It only knows what cylinders
   there are, and the plot_info. And it just used to look at the sensor
   number in the plot_info, and be done with that. That number no longer
   exists.

 - I have tested it, and I think the code is better, but hey, it's a
   fairly large patch to some of the more complex code in our code base.
   That "interpolate missing pressure fields" code really isn't pretty. It
   may be prettier, but..

Anyway, without further ado, here's the patch. No sign-off yet, because I
do think people should look and comment. But I think the patch is fine,
and I'll fix anythign that anybody can find, *except* for that TankItem
thing that I will refuse to touch. That class is ugly. It needs to have
access to the actual dive.

Note how it actually does remove more lines than it adds, and that's
despite added comments etc. The code really is simpler, but there may be
cases in there that need more work.

Known missing pieces that don't currently take advantage of concurrent
cylinder pressure data:

 - the momentary SAC rate coloring for dives will need more work

c5167f0039 Make sample pressure helper functions available to everybody
We had a "add_sample_pressure()" helper functions that was local to just
the libdivecomputer downloading code, but it really is applicable to
pretty much any code that adds cylinder pressure data to a sample.

Also add another helper: "legacy_format_o2pressures()" which checks the
sample data to see if we can use the legacy format, and returns the o2
pressure sensor to use for that legacy format.

Because both the XML and the git save format will need a way to save the
compatible old-style information, when possible, but save an extended
format for when we have data from multiple concurrent sensors.

adb4b66a05 Try to sanely download multiple concurrent cylinder pressures
This tries to sanely handle the case of a dive computer reporting
multiple cylinder pressures concurrently.

NOTE! There are various "interesting" situations that this whole issue
brings up:

 - some dive computers may report more cylinder pressures than we have
   slots for.

   Currently we will drop such pressures on the floor if they come for
   the same sample, but if they end up being spread across multiple
   samples we will end up re-using the slots with different sensor
   indexes.

   That kind of slot re-use may or may not end up confusing other
   subsurface logic - for example, make things believe there was a
   cylidner change event.

 - some dive computers might send only one sample at a time, but switch
   *which* sample they send on a gas switch event.  If they also report
   the correct sensor number, we'll now start reporting that pressure in
   the second slot.

   This should all be fine, and is the RightThing(tm) to do, but is
   different from what we used to do when we only ever used a single
   slot.

 - When people actually use multiple sensors, our old save format will
   start to need fixing.  Right now our save format comes from the CCR
   model where the second sensor was always the Oxygen sensor.

   We save that pressure fine (except we save it as "o2pressure" - just
   an odd historical naming artifact), but we do *not* save the actual
   sensor index, because in our traditional format that was always
   implicit in the data ("it's the oxygen cylinder").

so while this code hopefully makes our libdivecomputer download do the
right thing, there *will* be further fallout from having multiple
cylinder pressure sensors.  We're not done yet.

1e38d9239a Start cleaning up sensor indexing for multiple sensors
This is a very timid start at making us actually use multiple sensors
without the magical special case for just CCR oxygen tracking.

It mainly does:

 - turn the "sample->sensor" index into an array of two indexes, to
   match the pressures themselves.

 - get rid of dive->{oxygen_cylinder_index,diluent_cylinder_index},
   since a CCR dive should now simply set the sample->sensor[] indices
   correctly instead.

 - in a couple of places, start actually looping over the sensors rather
   than special-case the O2 case (although often the small "loops" are
   just unrolled, since it's just two cases.

but in many cases we still end up only covering the zero sensor case,
because the CCR O2 sensor code coverage was fairly limited.

It's entirely possible (even likely) that this migth break some existing
case: it tries to be a fairly direct ("stupid") translation of the old
code, but unlike the preparatory patch this does actually does change
some semantics.

For example, right now the git loader code assumes that if the git save
data contains a o2pressure entry, it just hardcodes the O2 sensor index
to 1.

In fact, one issue is going to simply be that our file formats do not
have that multiple sensor format, but instead had very clearly encoded
things as being the CCR O2 pressure sensor.

But this is hopefully close to usable, and I will need feedback (and
maybe test cases) from people who have existing CCR dives with pressure
data.

11a0c0cc70 Unify sample pressure and o2pressure as pressure[2] array
We currently carry two pressures around for all the samples and plot
info, but the second pressure is reserved for CCR dives as the O2
cylinder pressure.

That's kind of annoying when we *could* use it for regular sidemount
dives as the secondary pressure.

So start prepping for that instead: don't make it "pressure" and
"o2pressure", make it just be an array of two pressure values.

NOTE! This is purely mindless prepwork.  It literally just does a
search-and-replace, keeping the exact same semantics, so "pressure[1]"
is still just O2 pressure.

But at some future date, we can now start using it for a second sensor
value for sidemount instead.

0e7d8993a2 Make cylinder merging a bit more careful
This makes some further updates to the new cylinder merging code:

 - avoid re-using the cylinder if the usage type (OC/diluent/O2) is
   different between the two dives, even if the gasmix might be the
   same.

 - avoid re-using a cylinder if the user has manually added pressure
   data for it (and the pressures don't match)

 - when deciding to reuse a cylinder, make sure that we merge as much of
   the type information as makes sense.

This will potentially result in more cylinders that might need manual
cleanup, but at least we won't be throwing out user data.  And in most
cases where merging happens, none of this is an issue (because the data
comes fresh from a dive computer, and won't have been manually edited to
trigger the new rules).

e2bbd0ceec Rewrite cylinder merging code from scratch
The old cylinder merging code depended on the preferred dive having all
the cylinders, and the newly merged dive was just forced to pick from
that existing set of cylinders.

That worked ok if you have a "main" dive computer that you have all the
gases programmed for, and you download that first, and then you download
any secondary data later.

But it completely messed up if the second dive computer had gases that
the first one didn't know about, and just basically ended up doing
random things.

This rewrites the whole thing to actually try to create a union of the
two sets of cylinders when merging, with sane matching so that if the
cylinders match you won't get duplicates.

Miika Turkia hit this when he only used one gas, but had several gases
defined in his OSTC that he downloaded after his Vyper (with had just
the single gas defined).

This should fix that case (at least it does for my xml merging test-case
that showed the same problem after some munging).

638e7fb28f Add cylinder equipment tooltips with gas volume
This adds tooltips for the equipment tab for each cylinder, showing the
amount of gas used.

When you mouse over the size and working pressure fields, the tooltip will
show the amount of gas used (along with start and end gas volumes). And
when you mouse over the start and end pressures, it will show the start
and end gas volumes, and the Z factor used.

I started doing this because of the gas volume questions in the last day
or two (and a few from a few weeks ago). When even Robert Helling starts
wondering about the effects of compressibility on the SAC calculation, our
numbers are clearly too opaque.

With these tooltips, at least you can see what went into the used gas
calculations, instead of having to add debugging options to print out Z
factors.

[ This patch also adds a "rint()" to get the rounding right in the
  gas_volume() function.  Although rounding to the nearst milliliter
  really doesn't matter, it's the right thing to do after doing FP

833683521a Stop trying to fix up pressure sensor indexes
This removes 'fixup_dc_cylinder_index()', which was added to fix up the
pressure sensor indexes from the Atomic Cobalt dive computer.

Even for the Cobalt it really shouldn't matter, because the
libdivecomputer backend for the Cobalt actually tries to do the right
thing.  See for example commit 8853a1ccd422 ("Associate the pressure
samples with the primary tank.") in libdivecomputer.

Some historical digging shows that the subsurface sample pressure index
code came in from commit e32ba4d6d8 ("Improve tank handling for
Cobalt"), dated Tue Oct 28 13:48:15 2014.

And the libdivecomputer "use the right cylinder" code was around the
same time (Fri Oct 10 20:29:17 2014 +0200).

So I suspect that subsurface needed the fixup based on an older version
of libdivecomputer.  Jef's patch is a couple of weeks before, but we may
not have tracked libdivecomputer religiously.

The reason to remove this code is because it can (and does) mess up the
sensor index when it is actually reliable, like in the multi-sensor case
of the Suunto EON Steel.

485c5a4ebd Fix per-cylinder SAC rate calculations when cylinder use isn't known
John Van Ostrand reports that when he dives using two cylinders using
sidemounts, the per-cylinder SAC rate display is very misleading.

What happens is that since the two cylinders are used together (but
without a manifold), John is alternating between the two but not
actually adding gas switches in the profile.  As a result, the profile
looks like only one cylinder is used, even though clearly the other
cylinder gets breathed down too.

The per-cylinder SAC rate calculations would entirely ignore the
cylinder that didn't have gas switch events to it, and looking at the
info window it would look like John had a truly exceptional SAC rate.

But then in the general statistics panel that actually takes the whole
gas use into account, the very different real SAC rate would show up.

The basic issue is that if we don't have full use information for the
different cylinders, we would account the whole dive to just a partial
set.  We did have a special case for this, but that special case only
really worked if the first cylinder truly was the only cylinder used.

This patch makes us see the difference between "only one cylinder was
used, and I can use the overall mean depth for it" and "more than one
cylinder was used, but I don't know what the mean depths might be".

eff4059802 Start using the actual cylinder data for gas switch events
Now that gas switch events always have indices into the cylinder table,
start using that to look up the gas mix from the cylinders rather than
from the gas switch event itself.  In other words, the cylinder index is
now the primary data for gas switch events.

This means that now as you change the cylinder information, the gas
switch events will automatically update to reflect those changes.

Note that on loading data from the outside (either from a xml file, from
a git/cloud account, or from a dive computer), we may or may not
initially have an index for the gas change event.  The external data may
be from an older version of subsurface, or it may be from a
libdivecomputer download that just doesn't give index data at all.

In that case, we will do:

 - if there is no index, but there is explicit gas mix information, we
   will look up the index based on that gas mix, picking the cylinder
   that has the closest mix.

 - if there isn't even explicit gas mix data, so we only have the event
   value from libdivecomputer, we will turn that value into a gasmix,
   and use that to look up the cylinder index as above.

 - if no valid cylinder information is available at all, gas switch
   events will just be dropped.

When saving the data, we now always save the cylinder index, and the gas
mix associated with that cylinder (that gas mix will be ignored on load,
since the index is the primary, but it makes the event much easier to
read).

It is worth noting we do not modify the libdivecomputer value, even if
the gasmix has changed, so that remains as a record of the original
download.

e0824ef9f3 Make gas change events always have a cylinder index

back about a year and a half ago, I started sanitizing the gas switch

cylinder index rather than just the gas mix that is switched to.

But that initial step only _allowed_ a gas switch event to be associated
with a particular cylinder, the primary model was still to just specify
the mix.

This finally takes the next step, and *always* associates a gas switch
event with a particular cylinder.  Instead of then looking up the
cylinder by trying to match gas mixes at runtime, subsurface now looks
it up when loading the dive initially as part of the dive fixup code.

The switch event still has an a separate gas mix associated with it, but
this patch also starts preparing for entirely relying on the gas mix in
the cylinder itself, by starting to pass in not just the event but also
the dive pointer to the routines that look up gas mix details.

9005274986 Make "is_gasmix_redundant()" more robust
The gas switch event handling is somewhat fragile, mostly because the
legacy event encoding for gas switches is odd.  It's also limited to
whole percentages, unlike our internal gas mix model.

In addition, it also ends up comparing the values to the raw permille
values, which is wrong for air, and wouldn't match our O2_IN_AIR which
is 209 permille (closest approximation to 20.946%).

So handle air separately, since "21" really is a valid oxygen value for
air, and should match 20.9%.  And use the proper accessor functions to
get the gasmix values.

eb5907ab3b Remove linear pressure interpolation detection code
Dirk says that divinglog hasn't been doing the linear pressure
interpolation for a long while, so we're doing extra dive fixups that
really aren't needed any more.

Also, the code is actually buggy: it only ever worked on the first
cylinder anyway (because only the first cylinder pressure_delta[] would
be initialized).  That was probably perfectly fine in practice, since
it's unlikely that many tech divers used old versions of divinglog
anyway, so the bug per se isn't a reason to remove it - but it is a sign
that the code was a bit hard to read, so let's get rid of it if there is
no reason to maintain it or fix it.

7be962bfc2 Move subsurface-core to core and qt-mobile to mobile-widgets
Having subsurface-core as a directory name really messes with
autocomplete and is obviously redundant. Simmilarly, qt-mobile caused an
autocomplete conflict and also was inconsistent with the desktop-widget
name for the directory containing the "other" UI.

And while cleaning up the resulting change in the path name for include
files, I decided to clean up those even more to make them consistent
overall.

This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.
