e794efaba6 Allow for more O2 sensors
The Divesoft Liberty has four O2 sensors. So far, we had a hard coded
limit of three sensors and crashed with a failed assert when we
encoutered more than three. This allows for up to
MAX_O2_SENSORS which is currently 6. The voting logic is adapted
accordingly: We sort the values and we keep deleting the values that
differ more than 20% by value from the closest. This follows what
Shearwater implements on their computers.

In some of the import/export functions the value is still hard
coded to 6 thanks to explicit field names.

429230ced1 saving: fix resource leak found by coverity
fp_get_data() returns a copy of a string that must be freed.
Fix this in save-git.c. The analogous function in save-xml.c
has already been fixed. However, change the code to be more
idiomatic: since we own the pointer, make it "char *" instead
of "const char *". Then we don't have to cast on free().

Ultimately, we really should change string manipulation code
to C++.

9c253ee6c5 core: introduce divelog structure
The parser API was very annoying, as a number of tables
to-be-filled were passed in as pointers. The goal of this
commit is to collect all these tables in a single struct.
This should make it (more or less) clear what is actually
written into the divelog files.

Moreover, it should now be rather easy to search for
instances, where the global logfile is accessed (and it
turns out that there are many!).

The divelog struct does not contain the tables as substructs,
but only collects pointers. The idea is that the "divelog.h"
file can be included without all the other files describing
the numerous tables.

To make it easier to use from C++ parts of the code, the
struct implements a constructor and a destructor. Sadly,
we can't use smart pointers, since the pointers are accessed
from C code. Therfore the constructor and destructor are
quite complex.

The whole commit is large, but was mostly an automatic
conversion.

One oddity of note: the divelog structure also contains
the "autogroup" flag, since that is saved in the divelog.
This actually fixes a bug: Before, when importing dives
from a different log, the autogroup flag was overwritten.
This was probably not intended and does not happen anymore.

2f4b415e91 Saves default sea water salinity in log

dee13bf410 git access: save to local repository before doing remote access
.. at least if the local repository exists and can be opened.

If the local repo cannot be directly opened, we will still try to sync
with the remote first, but this way the *common* git save situation is
that we save locally before we then try to sync with the remote.

That means that if we have network problems, the save will happen before
we possibly hang due to really really slow networking.

7e632173e0 Collect and convert git repo data to 'struct git_info'
We have this nasty habit of randomly passing down all the different
things that we use to look up the local and remote git repository, and
the information associated with it.

Start collecting the data into a 'struct git_info' instead, so that it
is easier to manage, and easier and more logical to just look up
different parts of the puzzle.

This is a fairly mechanical conversion, but has moved all the basic
information collection to the 'is_git_repository()' function.  That
function no longer actually opens the repository (so the 'dry_run'
argument is gone, and instead a successful 'is_git_repository()' is
followed by 'opn_git_repository()' if you actually want the old
non-dry_run semantics.

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)

3bfd448b59 filter: implement saving of filter presets to git repositories
On the mailing list it was decided that users might want to
move their filter presets across computers via the cloud.
Notably, in the future one might access statistics on mobile and
these might by controlled by filter presets.

The git save routines use the same string formatting as the
XML save routines. The string formatting is found in
core/filterconstraint.cpp. Thus, duplication of code and
inconsistencies should be minimized.

Each filter preset is saved into a file in the "02-Filterpresets"
folder in the root of the git repository.

Each file consists of one "name" line, zero or one "fulltext" line
and zero or more "constraint" lines.

The modes, types and the actual payload is controlled via attributes.
Thus, a preset file might look like this:

name "test"
fulltext mode="substring" query="clown"
constraint type="location" stringmode="starstwith" data="mafia"
constraint type="sac" rangemode="range" negate data="5000,10000"

7c9f46acd2 Core: remove MAX_CYLINDERS restriction
Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.

Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.

One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit
architecture, so passing on the stack is probably not even significantly
slower than passing as reference.

1) Delete single-use dive site.
2) Save (dive site deleted)

Therefore, as a quick-fix, keep the referenced dive site around.
Note that this also means that empty dive sites must not be
deleted, as it might refer to a dive in the undo system. Instead
only clear references to empty dive sites in the global dive
table. Factor this functionality out, as it was common to the

64e6e435f8 Core: remove "when" field of struct dive_trip
The when field gives the time of the first dive. Instead of keeping
this field in sync, replace it by a function that determines the time
of the first dive.

26f6d95305 Core: Do not crash on save dives with no dive site (git storage)
And fix a crash very similar to the previous commit. When trying to
save (to git) with an empty dive site, ssrf crashes.

Again, add a simple guard to prevent this.
