This includes using the C++ version of membuffer. There appears
to not have been a leak, because the buffer is freed in
flush_buffer(), but usage was somewhat inconsistent and hard to
follow.
Also, convert some string handling to std::string to avoid free()

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.

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++.

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.

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.

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)

Users might want to move their presets with there log-file. Therefore,
save the presets to the log. The alternative would be to save them
to the preferences. However, on the mailinglist it was decided that
moving the presets to a mobile device is a wanted feature.
The XML saving code has a rather reasonable interface, therefore
this turned out to be pretty easy to implement.
The filter presets are saved into a
<filterpresets>
...
</filterpresets>
block
Each individual preset is saved into a
<filterpreset name='...'>
...
</filterpreset>
Block with a unique name attribute.
Each preset contains zero or one fulltext and zero or more constraint entries.
The type and mode(s) are controlled by attributes, the "payload" is saved in
the block. Note that all the formatting is done by functions in core/filterconstraint.c
and not the parser itself.
A preset in the XML file might look like this:
<filterpreset name='test1'>
<fulltext mode='startswith'>Train</fulltext>
<constraint type='planned'>0,0</constraint>
<constraint type='sac' range_mode='range' negate='1'>5000,10000</constraint>

Instead of accessing the cylinder table directly, use the get_cylinder()

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.

It turns out that the dive site saving was subtly but horribly buggy.
To save the value of the dive site, it did
show_utf8_blanked(b, t->value, " value='", "'/>\n", 1, anonymize);
which looks sane on the face of it, but the problem is that it puts the
final closing xml marker in the 'append this at the end' case.
That means that if the value is empty, the value won't be saved, but
neither will the closing tag. Resulting in an xml line that looks like
this:
<geo cat='3' origin='0' <geo cat='5' origin='0' value='Other name'/>
where the first geo tag was saved without the ending marker.
That then makes all the xml nesting entirely wrong, and the whole file
fails to save.
Now, the code around it does check that 't->value' is not NULL, but it
doesn't check for a value that is empty or all spaces (which also will
make 'show_utf8()' just skip it.
Fix it by saving the end marker separately:
show_utf8_blanked(b, t->value, " value='", "'", 1, anonymize);
put_format(b, "/>\n");
so that the xml is valid even if the goe marker value wasn'r.
