[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] Collect all arg tokens for stringification
...
Now all the tokens in the arg go into the one string.

[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 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).

[qfcc] Create a preprocessor token type
...
This will be used for unifying preprocessing and parsing, the idea being
that the tokens will be recorded for later expansion via macros, without
the need to retokenize.
