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.
