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.

Replace the UUID reference of struct dive by a pointer to dive_site.
This commit is rather large in lines, but nevertheless quite simple
since most of the UUID->pointer work was done in previous commits.

This changes more of the dive-site interface to return pointers
instead of UUIDs. Currently, most call sites directly extract
UUIDs afterwards. Ultimately, the UUIDs will be generally replaced
by pointers, which will then simplify these callers.

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.

This variable was only used in the divinglog_dive() function. There,
it was initialized right at the beginning and therefore there seems
to be no point in conserving its value across function-calls.
Make the variable local and remove the global version.

In a previous commit, the get_gasmix_* functions were changed to
return by value. For consistency, also pass gasmix by value.
Note that on common 64-bit platforms struct gasmix is the size
of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the
same space on the stack. On 32-bit platforms, the stack use
is probably doubled, but in return a dereference is avoided.
Supporting arbitrary gas-mixes (H2, Ar, ...) will be such an
invasive change that going back to pointers is probably the
least of our worries.
This commit is a step in const-ifying input parameters (passing
by value is the ultimate way of signaling that the input parameter
will not be changed [unless there are references to said parameter]).
