3bd391d01f [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.

ffb2514e75 [qfcc] Implement #include and search paths
Other than some trouble with line comments and continuation lines, it
seems to work nicely.

f1f0a4a260 [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.

717be4a12d [qfcc] Update pragma handling for the preprocessor
This removes the now redundant flex rules, though does spread
preprocess-only checks around a little more.

dc598c58b5 [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.

e60f538664 [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).

3307ef77ec [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.

8341f48f9d [qfcc] Implement #undef
That was pleasantly easy :)

5cab587207 [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.

5794c68bda [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).
