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.

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.

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.

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.
Found by Coverity. Fixes CIDs 350124, 350113, 350106, 350099, 350091

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.

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.

The starTimestamp is 4 hours apart on 2 different DCs within the sample
log. DiveDate on the dive_logs table seems to be correct, but must be
converted from human readable format.

Seems that Shearwater cloud stores sample rate into the database and
it is not constant within the log.

This works to some extent to part of a sample log I received. However,
still quite a bit more work is needed.

I encountered this while implementing Shearwater Cloud import, but it
makes sense to increase the size for dive id for Shearwater Desktop as
well.

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 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.
