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.

2b1db9da82 core: load and save fingerprints to XML
We always use the global fingerprint table - maybe this should just not
be a parameter of the accessor functions?

The syntax is very simple - the raw data is encoded as a hex string, the
rest of the components are hex numbers.

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.

a261466594 parser: add device_table to parser state
If we want to avoid the parsers to directly modify global data,
we have to provide a device_table to parse into. This adds such
a state and the corresponding function parameters. However,
for now this is unused.

Adding new parameters is very painful and this commit shows that
we urgently need a "struct divelog" collecting all those tables!

a7bbb6c1cc filter: remove filter_preset_table_t
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.

41cf83583d filter: load filter presets from XML files
This is a bit painful: since we don't want to modify the filter
presets when the user imports (as opposed to opens) a log,
we have to provide a table where the parser stores the presets.
Calling the parser is getting quite unwieldy, since many tables
are passed. We probably should introduce a structure representing
a full log-book at one point, which collects all the things that
are saved to the log.

Apart from that, this is simply the counterpart to saving to XML.
The interpretation of the string data is performed by core
functions, not the parser itself to avoid code duplication with
the git parser.

7f1def8602 cleanup: use taxonomy_set_category() function
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.

4f3b26f9b6 Implement Seac SeacSync databaser parser.
Dives for the seac action computer are imported by the seacsync
program into two tables in an sqlite3 database.

The dive information is read from the headers_dive table.
The dive_data table is then queried for each dive to get samples.

The seac action computer is the only current supported computer
by the seacsync program. It only supports two gas mixes, so the
parser will toggle between two cylinders whenever it detects a
change in the active O2 mix.

Dive start time is stored in UTC with a timezone offset.
A helper function to read this was added to qthelper.

Default cases have been added to some switch statements
to assist in future development for other dive types and
salinity.

Example database has been added to ./dives/TestDiveSeacSync.db

989d6a3f96 media: use table instead of linked list for media
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.

8df3705152 Cleanup: return cylinder from cylinder_start() in parser
Most callers of this function accessed the newly generated cylinder
immediately after calling this function. Thus, for convenience,
return the added cylinder. This avoids a number of verbose expressions.

On the flip side, cylinder_start() now has to be cast to
function returning void in a the "nesting" function table.

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.

a5e7f4253a Core: dynamically resize weight table
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
weightsystems. Thus, ownership of the description string is
taken when adding a weightsystem. An extra function adds
a cloned weightsystem at the end of the table.

138f27f65d Parser: make parser (mostly) reentrant
Introduce a parser_state structure, which describes (most) of the
global parser state. Create such a structure in the entry routines
to the parser and pass it down to the individual functions. The
parser state is initialized and freed with the init_parser_state()
and free_parser_state() functions.

The main benefits are:
1) Isolation of parser state.
2) Keeping the global name space tidy.
3) Prevent memory leaks which could happen in truncated files by
   freeing all the parser state after parse.

A somewhat controversial point might be that the individual
parsing functions are split in those that need parser-state and
those that don't. This means that there are now two versions of
the MATCH macro, viz. one for the former and one for the latter.

Instead of having people treat latitude and longitude as separate
things, just add a 'location_t' data structure that contains both.

Almost all cases want to always act on them together.

This is really just prep-work for adding a few more locations that we
track: I want to add a entry/exit location to each dive (independent of
the dive site) because of how the Garmin Descent gives us the
information (and hopefully, some day, other dive computers too).

2de8e70ab0 Parser: move match() into core/parse-xml.c
The match() function compares a pattern with a name with
a twist: The name may either end in '\0' or '.'. If pattern
and name match, a parsing function is called on a buffer and
a destination value. The result of the parsing is not checked.

This seems awfully XML-specific and therefore move the function
from the general parse.c to the specialized parse-xml.c unit
and make it of local linkage.
