a1e6df46d9 core: move functions into struct dive
Nothing against free-standing functions, but in the case
of dc_watertemp(), dc_airtemp(), endtime() and totaltime(),
it seems natural to move this into the dive class and avoid
polution of the global name space.

284582d2e8 core: turn divecomputer list into std::vector<>
Since struct divecomputer is now fully C++ (i.e. cleans up
after itself), we can simply turn the list of divecomputers
into an std::vector<>. This makes the code quite a bit simpler,
because the first divecomputer was actually a subobject.

Yes, this makes the common case of a single divecomputer a
little bit less efficient, but it really shouldn't matter.
If it does, we can still write a special std::vector<>-
like container that keeps the first element inline.

This change makes pointers-to-divecomputers not stable.
So always access the divecomputer via its index. As
far as I can tell, most of the code already does this.

c27314d603 core: replace add_sample() by append_sample()
add_sample() was used in only one place, and the return value was
always ignored. It took a time parameter, suggesting that a sample
could be added anywhere, but in reality the sample was added at
the end of the list. It used prepare_sample() that copies data
from the previous sample, just to overwrite it with the newly
added sample.

All in all very weird. Simplify the function: just append the
passed in sample and name it accordingly.

27dbdd35c6 core: turn event-list of divecomputer into std::vector<>
This is a rather long commit, because it refactors lots of the event
code from pointer to value semantics: pointers to entries in an
std::vector<> are not stable, so better use indexes.

To step through the event-list at diven time stamps, add *_loop classes,
which encapsulate state that had to be manually handled before by
the caller. I'm not happy about the interface, but it tries to
mirror the one we had before.

f120fecccb core: use std::vector<> to store divecomputer samples
This is a hairy one, because the sample code is rather tricky.

There was a pattern of looping through pairs of adjacent samples,
for interpolation purposes. Add an range adapter to generalize
such loops.

Removes the finish_sample() function: The code would call
prepare_sample() to start parsing of samples and then
finish_sample() to actuall add it. I.e. a kind of commit().

Since, with one exception, all users of prepare_sample()
called finish_sample() in all code paths, we might just add
the sample in the first place. The exception was sample_end()
in parse.cpp. This brings a small change: samples are now
added, even if they could only be parsed partially. I doubt
that this makes any difference, since it will only happen
for broken divelogs anyway.

This allows us to use non-C member variables. Convert a number

it mixed owning and non-owning pointers. Mad.

1aa5438b2d Cleanup: Improve the Use of 'Planned dive' and 'Manually added dive'.
- standardise the naming;
- use it consistently;
- apply the 'samples < 50' only when putting manually added dives into
  edit mode - everywhere else manually added dives should be treated as
  such;
- do not show a warning before editing a manually added dive in planner.

f687e51d4b core: don't consider dives with many samples as manually added
This causes UI confusion. Notably we go into edit mode and
reduce the number of samples, leading to loss of information.

If someone really manually adds a dive with more than 50
samples, they should still be able to explicitly open the
dive in the planner.

6c4e890960 Clean up divecomputer 'device' handling
We have this odd legacy notion of a divecomputer 'device', that was
originally just basically the libdivecomputer 'EVENT_DEVINFO' report
that was associated with each dive.  So it had firmware version,
deviceid, and serial number.

It had also gotten extended to do 'nickname' handling, and it was all
confusing, ugly and bad.  It was particularly bad because it wasn't
actually a 'per device' thing at all: due to the firmware field, a dive
computer that got a firmware update forced a new 'device'.

To make matters worse, the 'deviceid' was also almost random, because
we've calculated it a couple of different ways, and libdivecomputer
itself has changed how the legacy 32-bit 'serial number' is expressed.

Finally, because of all these issues, we didn't even try to make the
thing unique, so it really ended up being a random snapshot of the state
of the dive computer at the time of a dive, and sometimes we'd pick one,
and sometimes another, since they weren't really well-defined.

So get rid of all this confusion.

The new rules:

 - the actual random dive computer state at the time of a dive is kept
   in the dive data. So if you want to know the firmware version, it
   should be in the 'extra data'

 - the only serial number that matters is the string one in the extra
   data, because that's the one that actually matches what the dive
   computer reports, and isn't some random 32-bit integer with ambiguous
   formatting.

 - the 'device id' - the thing we match with (together with the model
   name, eg "Suunto EON Steel") is purely a hash of the real serial
   number.

   The device ID that libdivecomputer reports in EVENT_DEVINFO is
   ignored, as is the device ID we've saved in the XML or git files. If
   we have a serial number, the device ID will be uniquely associated
   with that serial number, and if we don't have one, the device ID will
   be zero (for 'match anything').

   So now 'deviceid' is literally just a shorthand for the serial number
   string, and the two are joined at the hip.

 - the 'device' managament is _only_ used to track devices that have
   serial numbers _and_ nicknames. So no more different device
   structures just because one had a nickname and the other didn't etc.

   Without a serial number, the device is 'anonymous' and fundamentally
   cannot be distinguished from other devices of the same model, so a
   nickname is meaningless. And without a nickname, there is no point in
   creating a device data structure, since all the data is in the dive
   itself and the device structure wouldn't add any value..

These rules mean that we no longer have ambiguous 'device' structures,
and we can never have duplicates that can confuse us.

This does mean that you can't give a nickname to a device that cannot be
uniquely identified with a serial number, but those are happily fairly
rare (and mostly older ones).  Dirk said he'd look at what it takes to
give more dive computers proper serial numbers, and I already did it for
the Garmin Descent family yesterday.

(Honesty in advertizing: right now you can't add a nickname to a dive
computer that doesn't already have one, because such a dive computer
will not have a device structure.  But that's a UI issue, and I'll sort
that out separately)

0e196310f9 cleanup: split out divecomputer functions from dive.c
Since dive.c is so huge, split out divecomputer-related functions
into divecomputer.[c|h], sample.[c|h] and extradata.[c|h].

This does not give huge compile time improvements, since
struct dive contains a struct divecomputer and therefore
dive.h has to include divecomputer.h. However, it make things
distinctly more clear.

a01ab81713 cleanup: fold core/divecomputer.cpp into core/device.c
core/device.h was declaring a number of functions that were related
to divecomputers (dcs): creating a fake dc for manually entered dives
and registering / accessing dc nicknames. On could argue whether
these should be lumped together, but it is what it is.

However, part of that was implemented in C++/Qt code in a separate
core/divecomputer.cpp file. Some function therein where only
accessible to C++ and declared in core/divecomputer.h.

All in all, a big mess. Let's simply combine the files and
conditionally compile the C++-only functions depending on
the __cplusplus define.

Yes, that means turning device.c into device.cpp. A brave soul
might turn the C++/Qt code into C code if they whish later on.

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.
