f9c3227975 cleanup: remove system includes from dive.c
Let the various source files include the system headers they need
themselves.

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!

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.

d3d51b175d Cleanup: pass NULL pointer for error string pointer
Since we never did anything with the error string, why even ask for it.
And this way we don't have to deal with the memory returned, either.

6200909ba4 Cleanup: move tag functions into own translation unit
Make dive.h a bit slimmer. It's only a drop in the bucket - but at
least when modifying tag functions not the *whole* application is
rebuilt anymore.

37146c5742 Parser: parse into custom dive site table
To extend the undo system to dive sites, the importers and downloaders
must not parse directly into the global dive site table. Instead,
pass a dive_site_table argument to parse into.

For now, always pass the global dive_site_table so that this commit
should not cause any functional change.

7e33369dc8 Parser: add trip_table parameter to parsing functions
To allow parsing into arbitrary trip_tables, add the corresponding
parameter to the parsing functions and the parser state. Currently,
all callers pass the global trip_table so there should be no change
in functionality. These arguments will be replaced in subsequent commits.

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.

076419d757 DM5 import: support for larger sample size
Suunto has updated SampleBlob to use 30 byte blobs. This adds support
for the increased size. Note that this only parses the same fields we
have parsed before. (Currently I have no idea what the increased size is
used for.)

Note also that I do not currently have data with the new format so I
only tested this still works with old data.

06a2f36a62 Start to describe DM5 sampleBlob
Currently the best guess of sampleBlob format. Unfortunately there seems
to be some version of DM that stores the temperature in different
location that I have not been able to figure out yet. Note that some
version of DM does not utilize sampleBlob but specific blobs for each
value (temperature, pressure, ...).
