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.

So far, we added a non-global device table to the parser states.
Now, create device nodes in that table instead of in the global
table. Thus, on undo of dive-import, the new device nodes will
be removed.

In analogy to the xml-parser add a device-table to git's parser-state.
Currently this is unused. In upcoming commits the git parser will
then be changed to add device nodes in this table instead of the
global device table. The long-term goal being to detach the
parsers from global state and to make dive-import fully undoable.

We used a typedef "filter_preset_table_t" for the filter preset table,
because it is a "std::vector<filter_preset>". However, that is in
contrast to all the other global tables (dives, trips, sites) that we
have.
Therefore, turn this into a standard struct, which simply inherits
from "std::vector<filter_preset>". Note that while inheriting from
std::vector<> is generally not recommended, it is not a problem
here, because we don't modify it in any shape or form.

Instead of accessing the global device table directly, add a parameter
to all device-table accessing functions. This makes all places in
the code that access the global device table grep-able, which is
necessary to include the device-table code in the undo system.

This is mostly copy and paste of other git loading code. Sadly,

Instead of manipulating the taxonomy structures directly, use the
taxonomy_set_category() function. This improves encapsulation and
gives us the possibility to improve the taxonomy data structures.
This concerns three places:
1) git parser
2) XML parser
3) reverse geo-lookup
This improves the XML parser code slightly: The parser assumes that
the value-attribute comes last (after origin and category). While
it still does that, it now at least generates a warning if it encounters
a value-attribute without origin- or category-attribute.

This warning is unnecessarily scary - we had a problem with parsing
multiple strings on the same line, but it should be all solved, and
while it does mean that people may have old incorrect git save files
with empty strings, scaring users about it isn't going to help.
And with the warning removed, we can just remove the whole test for an
empty string, because the normal code sequence handles that case just
fine.

For consistency with equipment, use our table macros for pictures.
Generally tables (arrays) are preferred over linked lists, because
they allow random access.
This is mostly copy & paste of the equipment code.
Sadly, our table macros are quite messy and need some revamping.
Therefore, the resulting code is likewise somewhat messy.

No point in slurping in all of dive.h for translation units that only

Don't call the header "time.h", because we don't want to end up in a

This will be temporarilly used by the planner to mark consumption of
air at the surface. Do this by creating a new function add_cylinder,
which replaces add_to_cylinder_table() and takes care of always adding
a dummy cylinder at the end of the table. Make the original
add_to_cylinder_table() local, so that it cannot be accessed anymore.

I would have bet money that Android used to send stderr to the logcat
log, but apparently it doesn't (anymore?). So in order to be able to
have a chance to debug weird cloud storage issues on Android, let's do
some wholesale replacement of fprintf(stderr,...) with our own version
of the INFO macro that we long ago borrowed from libdivecomputer (and
rename it to ensure we don't have a conflict there).

The pop_cstring() function is used by the git parser to
duplicate a quoted string. On error, it returns an empty
string literal. Since the caller expects a copied string
and takes ownership of that string, it will ultimately
be freed.
Concrete example: a log with erroneous cylinder data was opened
getting such an empty string literal as description. On closing or
syncing with the cloud, the dive is freed, leading to a free
of the string literal -> crash.
Return a copy of the empty string instead.

Because of the multiple string confusion, we'd get the names wrong for
modechange events. If we then made other changes to the dive and saved
the end result back, they'd now be wrong in the git cloud storage too.
Fix it up manually by just noticing that there's a 'divemode' string on
the event line, which can only happen with modechange events.
Maybe we should report the fixup? This just silently fixes it (but only
for the git save format).

We had some fairly obscure rules for how strings were parsed, and it
actually caused bugs when the same line had multiple strings in it.
That normally doesn't happen, and the cases where it was _supposed_ to
happen had special cases for it (divecomputer ID lines, and tag lines).
But by mistake, we had introduced a case of that for the event line
handling in commit b9174332d ("Read and write divemode changes (xml and
git)"), and nobody realized that the divemode string addition meant that
"oops, now it's corrupting the event name". An event line could look
like this:
event 40:00 type=8 divemode="OC" name="modechange"
where we now had both that "OC" and "modechange" strings, and the code
to pick the name just picked the first string. So we'd end up
effectively mis-parsing the above line as
event 40:00 type=8 divemode="OC" name="OC"
which is obviously wrong.
The dive mode didn't really need to be a string in the first place
(there is nothing to quote, and no spaces in it), but hey, here we are.
We can't just magially fix the existing broken saves.
So make it more straightforward to handle strings in the git format line
parser. We still stash the different decoded strings together in one
special memory buffer, but now the parser helpers automatically untangle
it as they traverse the key value pairs.
This is still overly subtle code, and it doesn't fix the cases where
we've saved the wrong data back. That comes later.

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.

The git parser was using a number of global static variables. Remove
them by introducing a parser state, which is passed down to the
call hierarchy.
Advantages:
1) Removes global variables and makes the parser (mostly) reentrant.
2) More flexible - e.g. when parsing samples, the parser can now
access the dive to check if the cylinder number is valid.
3) Less weak typing through "void *".

Replace the fixed-size weightsystem table by a dynamically
relocated table. Reuse the table-macros used in other parts
of the code.
The table stores weightsystem entries, not pointers to

The parse_location() function was used in three places. In two
of them, the declaration was in the translation unit. Instead,
move the declaration into a header file, to avoid duplication
and the possibility of inconsistencies.
The "units.h" header was chosen as this is where location_t
is defined.
Moreover, make the string argument to parse_location() "const
char *", so that it can be used on non-owned buffers.

printGPSCoords() returned a newly allocated C-style string. Most
callers simply made a QString out of it and freed the C-style string.
This is paradoxical, as printGPSCoords internally works with QStrings
and converts them to C-style on return.
Therefore, let printGPSCoords() return a QString and create a
printGPSCoordsC() wrapper for the two C-callers.

The printGPSCoords() function returns a copied C-style string. Since
the owndership is transferred to the caller, the correct return type
is "char *" instead of "const char *".
Thus a number of casts when calling free can be removed.
Moreover a number of callers didn't free the string and thus were
leaking memory. Fix them. Ultimately we might want two versions
of the function: one for QString, one for C-style strings.

There were two versions of the insert_trip() function: one
would merge trips if a trip with the same date already existed,
the other wouldn't. The latter was introduced with the dive-list
undo work.
The problem is that the "date" of a trip (i.e. the first dive)
seems ill-defined as this is a volatile value. Moreover in
the context of making dive-import undoable this is a very
dangerous notion, as the caller needs control over when the dives
are added to a trip.
Therefore, unify these two functions and never merge trips.
The decision on merging dives now has to made by the caller.
This will be implemented in a future commit.
