Misc. minor fixes and adjustments

Daniel-Cortez commented 4 years ago

What this PR does / why we need it:

Fixes build errors on Linux and OS X (see https://github.com/pawn-lang/compiler/pull/601#issuecomment-720541010) caused by mixed declarations of array sc_tokens (extern char *sc_tokens[] vs. extern const char *sc_tokens[]) by moving the array to scvars.c and replacing all of its definitions in several source files by a single definition in sc.h.
Removes the unused uPREDEF flag. After the addition of flag flagPREDEF (which is a direct successor to uPREDEF), uPREDEF is only checked in delete_symbols(), but never set.
Removes function finddepend(). After the addition of the symbol::child field in 73d4934d61d0825c32faa461e9e9e7bbc99cbf38, finddepend() became redundant.
Makes operator __pragma use a more reliable method of detecting packed strings. The previous method didn't allow to detect empty packed strings, because internally !"" is the same as "".
Other fixes and adjustments that don't deserve a separate PR.

I merged a load, but couldn't merge this one. There were a load of merge conflicts, which while I'm sure I could have solved individually, I can't be sure wouldn't have broken all the work. Like some new places introduced where some of these changes should be but aren't.

No problem, I'll update it. EDIT: Done.
