[qfcc] Ensure macros expand for #elif
...
It seems I wasn't quite paying attention to when I should be getting
that invalid directive error for #version and when I shouldn't.

[qfcc] Parse parameterless function-type macros
...
This allows `#define foo()` to work as expected.

[qfcc] Implement parsing side of ... macros
...
Expansion is not yet implemented (need __VA_OPT__ and __VA_ARGS__), but
this gets scheme compiling.

[qfcc] Grab undef id early
...
I'm unsure of the small string handling is a premature optimization, but
when most tokens are small...

[qfcc] Get vkgen compiling
...
Or at least mostly so. The __QFCC__ define isn't visible, and it seems
undef might not be working properly (ruamoko/lib/types.r doesn't
compile). Of course, there's still the issue of whether it's compiling
correctly.

[qfcc] Add a #notice directive
...
Haven't got things working properly and I'm already extending the
preprocessor :P. It proved handy for debugging :)

[qfcc] Treat all identifiers as undefined
...
If ID gets to the preprocessor parser in expressions, the ID is not
defined because if it was defined, it would have been expanded. Thus,
all IDs are 0.

[qfcc] Handle h-string and q-string only in #include
...
And #embed, though that's not implemented yet. Comparisons eating
multiple lines results in some rather interesting errors.

[qfcc] Implement #include and search paths

Other than some trouble with line comments and continuation lines, it
seems to work nicely.

[qfcc] Update line directive handling
...
In addition to cleaning up the old flex line rules, this improves
handling of the '# num "file" flags' from cpp to at least parse the
additional flags (support for the system header flag might come later,
but I doubt the extern-c flag will have much meaning).
QuakePascal has lost its line directive handling (no errors, but dead
rules) for now. Eventually the lexers will be merged.

[qfcc] Update pragma handling for the preprocessor
...
This removes the now redundant flex rules, though does spread
preprocess-only checks around a little more.

[qfcc] Record and expand macro arguments
...
Stringizing doesn't work correctly (stringizes only the first token, not
the whole argument), but things seems to work otherwise.

[qfcc] Implement function-type macro argument parsing
...
The arguments are not recorded yet, but argument parsing can consume the
whole file if the closing ) is missing (same as gcc).

[qfcc] Implement object-type macro expansion
...
Really, function-type macros expand too, but incorrectly as the
parameters are not parsed and thus not expanded, but this gets the basic
handling implemented, including # and ## processing.

[qfcc] Implement macro recording and defined()

So far, very consistent with gcc's cpp from my limited testing, though
some error handling may be a little different.

[qfcc] Implement basic conditional compilation
...
Just #if, #else and #endif for now. However, much of the preprocessor
parsing working minus the semantics (expressions do work, though).
