ac9bab7e2f Autogroup only when selected
Comits f427226b3b and 43c3885249 of the undo series introduced 2 calls
of autogroup_dives() without checking the autogroup global boolean.
This is a bug. An import from DC (for example) then triggers an
autogrouping, the divelist is autogrouped, and the UI button
is off.

This commit solves this. I've chosen for a guard in the autogroup_dives()
that now is a no-op when called when the user did not select autogrouping.
In additon, simplified the other calls to this function, as we do
not need to check before calling any more.

954820aa81 Dive site: explicitly init displayed_dive_site on show widget
The global object "displayed_dive_site" is used to store the
old dive site data for the edit-dive-site widget. The fields
of the widget were initialized from this object in the show
event. Therefore the object was updated in numerous parts of
the code to make sure that it was up-to-date. Instead, move
the initialization of the object to the function that also
initiatlizes the fields. Call this function explicitly before
showing the widget.

This makes the data-fow distinctly easier to understand.

7067e33596 Undo: select dives after add, remove, merge, split dive commands
Select the proper dives after the add, remove, split and merge
dives commands on undo *and* redo. Generally, select the added
dives. For undo of add, remember the pre-addition selection.
For redo of remove, select the closest dive to the first removed
dive.

The biggest part of the commit is the signal-interface between
the dive commands and the dive-list model and dive-list view.
This is done in two steps:
1) To the DiveTripModel in batches of trips. The dive trip model
   transforms the dives into indices.
2) To the DiveListView. The DiveListView has to translate the
   DiveTripModel indexes to actual indexes via its QSortFilterProxy-
   model.

For code-reuse, derive all divelist-changing commands from a new base-class,
which has a flag that describes whether the divelist changed. The helper
functions which add and remove dives are made members of the base class and
set the flag is a selected dive is added or removed.

To properly detect when the current dive was deleted it
became necessary to turn the current dive from an index
to a pointer, because indices are not stable.

Unfortunately, in some cases an index was expected and these
places now have to transform the dive into an index. These
should be converted in due course.

0d98da5261 Dive list: remember selected dives
Don't delesect dives, when unregistering them from the backend.
If a previously selected dive is added, select it in the dive-list.
For this purpose introduce a SELECTED_ROLE to query the DiveTripModel

Unfortunately, when adding multiple selected dives, current_dive_changed
is called for each of them, making this very slow. This will have
to be fixed in subsequent commits.

6ac4ddbeed Core: introduce insert_trip_dont_merge() function
insert_trip() adds a trip to the backend, but merges trips if
there exists a trip with the same date. This is a disaster
for the MergeTrips command, because this command adds a new
trip and removes the previous two. Of course if the added trip
is merged, this cannot work.

Therefore, add an insert_trip_dont_merge() function, which
adds the trip, but doesn't merge.

f427226b3b Undo: make diverse trip-related operations undo-able
AddDivesToTrip, CreateTrip, AutogroupDives, RemoveAutogenTrips
and MergeTrips basically all did the same thing as RemoveDivesFromTrip,
which was already implemented. Thus, factor our the common functionality
and hook it up to make all these functions undo-able.

Don't do the autogroup-call everytime the dive-list is rebuilt
(that would create innumberable undo-actions), but only on dive-load /
import or if expressly asked by the user [by switching the autogroup
flag].

014c04f8bd Undo: implement rudimentary support for undo of dive-merging
For this, an output-parameter was added to the backend merge_dives()
function. When non-zero, instead of adding the merged dive to
the preferred trip, the preferred trip is returned to the caller.

Since the new UndoObject, just like the delete-dives UndoObject,
needs to remove/readd a set of dives, the corresponding functionality
was split-off in a helper function.

403dd5a891 Undo: fix multi-level undo of delete-dive and remove-dive-from-trip
The original undo-code was fundamentally broken. Not only did it leak
resources (copied trips were never freed), it also kept references
to trips or dives that could be changed by other commands. Thus,
anything more than a single undo could lead to crashes.

Two ways of fixing this were considered
1) Don't store pointers, but unique dive-ids and trip-ids.
   Whereas such unique ids exist for dives, they would have to be
   implemented for trips.
2) Don't free objects in the backend.
   Instead, take ownership of deleted objects in the undo-object.
   Thus, all references in previous undo-objects are guaranteed to
   still exist (unless the objects are deleted elsewhere).

After some contemplation, the second method was chosen, because
it is significantly less intrusive. While touching the undo-objects,
clearly separate backend from ui-code, such that they can ultimately
be reused for mobile.

Note that if other parts of the code delete dives, crashes can still
be provoked. Notable examples are split/merge dives. These will have
to be fixed later. Nevertheless, the new code is a significant
improvement over the old state.

While touching the code, implement proper translation string based
on Qt's plural-feature (using %n).

d2d9821170 Fix warning about unused variables
Commit 810903bdb9 ("Import: pass a dive table to process_imported_dives()")
introduced the variables

        struct dive *old_dive, *merged;

into process_imported_dives(), but never used them.  It seems to be an
artifact of having split the function to use the try_to_merge_into()
helper function (that has those same variable names and _does_ use
them), but forgetting the original variables from the pre-split case.

Gcc understandably warns about it:

  core/divelist.c: In function ‘process_imported_dives’:
  core/divelist.c:1351:26: warning: unused variable ‘merged’ [-Wunused-variable]
    struct dive *old_dive, *merged;

    struct dive *old_dive, *merged;
                 ^~~~~~~~

and the trivial fix is to just remove that line that declares the stale

6dc1dcaea5 Import: pass "downloaded" parameter to process_imported_dives()
process_imported_dives() is more efficient for downloaded than for
imported (from a file) dives, because it checks only the divecomputer
of the first dive.

This condition is checked via the "downloaded" flag of the first
dive. Instead, pass an argument to process_imported_dives().

e5dca8228e Import: remove dive->downloaded logic
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()
[i.e. pass old as first and new as second dive].

This makes marking of downloaded dives via a flag unnecessary.

810903bdb9 Import: pass a dive table to process_imported_dives()
Dives were directly imported into the global dive table and then
merged in process_imported_dives(). Make this interface more flexible,
by passing an independent dive table.

The dive table of the to-be-imported dives will be sorted and merged.
Then each dive is inserted in a one-by-one manner to into the global
dive table.

This actually introduces (at least) two functional changes:
1) If a new dive spans two old dives, it will only be merged to the
   first dive. But this seems like a pathological case, which is of
   dubious value anyway.
2) Dives unrelated to the import will not be merged. The old code
   would happily merge dives that were not even close to the
   newly imported dives. A surprising behavior.

c32e71e64d Dive information: fix surface interval calculation
The old surface interval calculation had fundamental issues:

1) process_all_dives(), which calculates the statistics over *all*
   dives was used to get the pointer to the previous dive.
2) If two dives in the table had the same time, one of those would
   have been considered the "previous" dive.
3) If the dive, for which the surface interval is calculated is
   not yet in the table, no previous dive would be determined.

Fix all this by creating a get_surface_interval() function and
removing the "get previous dive" functionality of process_all_dives().
Remove the process_all_dives() call from TabDiveInformation::updateData().

d3d06bc580 Cleanup: split out free_dive() function from delete_single_dive()
Currently, we can only delete dives that are indexed in the main
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()
function from delete_single_dive(), which takes an index into
the main dive table.

In the process, adopt the dive freeing-code from clear_dive(),
which frees more data than the code in delete_single_dive().
This potentially fixes a memory-leak.

35b8a4f404 Core: split process_dives() in post-import and post-load versions
process_dives() is used to post-process the dive table after loading
or importing. The first parameter states whether this was after
load or import.

Especially in the light of undo, load and import are fundamentally
different things. Notably, that latter should be undo-able, whereas
the former is not. Therefore, as a first step to make import undo-able,
split the function in two versions and remove the first parameter.

It turns out the the load-version is very light. It only sets the
DC nicknames and sorts the dive-table. There seems to be no reason
to merge dives.

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
const pointers.

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.

use the planner without actually planning).

7a82103c99 CNS calculation fix
Identify previous dives for CNS calculation in a similar way as it
is done for previous dives for deco calculation.
This is done to identify the previous dives dynamically when moving
around date/time of a dive in the planner.

4158a4c7de init_deco correctly identify previous dives and report overlapping dives
When changing the date/time of a dive in the planner the dive may end
up in a totaly new position in respect to date/time of other dives in
dive list table. It can be moved to the past or the future before or after
other existing dives. It also could overlap with an existing dive.

This change enables identification of a new "virtual" dive list position
and based on this starts looking for previous dives.
Then it (as before the change) does init the deco calculation with any
applicable previous dive and surface interval.
If some of these applicable dives overlap it returns a neg. surface time
which is then used in the planner notes to prohibit display of results.

7713c7e607 Use helper function dive_endtime() where apropriate
Calculating dive.when + dive.duration doesn't always give the correct
endtime of a dive especially when a dive has surface interval(s) in
the middle.
Using the helper function dive_endtime() fixes this issue.

defa71256f Use the right gasmix for deco calculations
In commit e1b880f4 "Profile support for multiple concurrent pressure
sensors" I had mindlessly hacked away at some of the sensor lookups from
the plot entries to make it all build, and forgotten about my butchery.

Thankfully Jan and Davide noticed in their multi-cylinder deco dives
that the deco calculations were no longer correct.

This uses the newly introduced "get_gasmix()" helper to look up the
currently breathing gasmix, and fixes the deco calculations.

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.

dec47e11cd Separate the download thread from the widget logic
This is important to not duplicate code for the Qml
view. Now the DownloadFromDiveComputer widget is mostly
free from important code (that has been upgraded to the
core folder), and I can start coding the QML interface.

There are still a few functions on the desktop widget
that will die so I can call them via the QML code later.

I also touched the location of a few globals (please, let's
stop using those) - because it was declared on the
desktop code and being used in the core.

406e4287eb Change calls to rint into lrint avoiding conversion warnings
Using gcc option "-Wfloat-conversion" is useful to catch
potential conversion errors (where lrint should be used).
rint returns double and still raises the same warning,
this is why this change updates all rint calls to lrint.
In few places, where input type is a float, corresponding
lrinf is used.

84166a4ee7 Extend time parsing to before 1970
It turns out that we are starting to have users that have logs that go
back that far. It won't be common, but let's get it right anyway.

NOTE! With us now supporting dates earlier in 1900, this also makes
"utc_mktime()" always add the "1900" to the year field.  That way we
avoid ever using the fairly ambiguous two-digit shorthand.

It didn't use to be all that ambiguous when we knew that any two-digit
number less than 70 had to be 2000+.  Now that we support going back to
earlier in the last centiry, that certainty is eroding.

590af9ae7d Add helper to find the dive closest to a given time
If we want to keep the selected dive "close" to where it was before an
operation (whether a delete, or a reload, or something like that), then
the most intuitive thing to do appears to be to select either the same
dive again (if it still exists), or one very close to it in time. This
helper allows us to identify the dive in the current dive list that is
closest to the given time.

We do this in the C code to ensure that we look at all dives in the
dive_table - based on the id that is returned the UI can then figure out
where this dive is currently shown.

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.
