Don't do a find_type on the parsed function.
...
This is needed for C style declarations, but breaks QuakeC style. The fix
is to do the find_type once the return type has been filled in.

The big type-system rewrite. Horribly broken :)
...
While broken, it is good enough to compile modulo.r.
This gives qfcc C's type system with QC specifics bolted on top (rather
than trying to cram C's type system into QC's). Pointers and arrays now
use C syntax and semantics (though I think there's a lot of breakage in
there at the moment). Functions themselves are still dual mode: both QC
style and C style are available.
