Get functions attempting to generate code.
...
However, the statements are only printed as expressions.

Get basic function creation working.
...
Even more FIXMEs, but the pascal parser can now create functions. The
function records even get emitted.

Rewrite much to use symbols and symtabs. Gut emit.c. Massive breakage.
...
That which isn't rewritten is horribly broken. However, this does include a
nice mechanism for building QC structs for emitting data.
emit.c has been gutted in the spirit of "throw one away".
There is much work to be done to get even variables emitted, let alone
code. Things should be a little more fun from here on.

Rework the lexer and parser to use symbols instead of defs.
...
Currently parses the test program just fine, but code generation is very
very broken.

Add a "void return" instruction.

I got fed up with always having to explicty return something.

Already extending QuakePascal, and many basics aren't there yet :P

Make QuakePascal programs runnable.
...
Generate a mini-main function (".main", to avoid namespace pollution) that
calls the function named by "program", and make qwaq check for ".main" as
well as "main". If both are present, ".main" will take priority.

Clean out some unnecessary types from the progs engine and clean up the mess.

This is a nasty commit, sorry, but 99% of the commit is interdependent.

The first stages of Quake-Pascal.
...
At present, this parses a subset of the pascal language with a few type
extensions. There is already work on the type system.
