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!

db6acfdd27 Update Shearwater sample time calculation
At least Shearwater Cloud seems to use multiple formats for sample time
recorded in the database. Sometimes the time is in seconds, sometimes in
milliseconds, and sometime it is something I have no idea about. Thus
switching to calculating the sample id myself and using sample interval
to calculate the actual sample time. Seems to be more reliable than
trying to guess what format Shearwater is using for this specific dive.

a7bed157b5 Grab the first gas on Shearwater import
The logic to retrieve gas changes from Shearwater cloud database is
detecting only when the O2/He chnages. This change will grab the initial
gas. (Problem was only shown when there was a gas changee in the log, so
cingle cylinder dives were working fine.)

794066b236 Cylinders: access cylinders with get_cylinder()
Instead of accessing the cylinder table directly, use the get_cylinder()
function. This gives less unwieldy expressions. But more importantly,
the function does bound checking. This is crucial for now as the code
hasn't be properly audited since the change to arbitrarily sized
cylinder tables. Accesses of invalid cylinder indexes may lead to
silent data-corruption that is sometimes not even noticed by
valgrind. Returning NULL instead of an invalid pointer will make
debugging much easier.

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.

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.

parameter to the parsing functions and the parser state. Currently,
all callers pass the global trip_table so there should be no change

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.

295c63211c Shearwater import: support for DC reported ceiling
This adds support for DC reported ceiling when importing the Shearwater
Desktop database. Both AI and non-AI versions are tested, but not all
possible paths. For non-AI the DC reported ceiling was from
firstStopDepth and for the AI version it was from the decoCeiling field.

I do not currently know when each of these fields are used, but at least
this works on my test data.
