Miscellaneous cleanup, still with the same suspects...

- in mdloadskin() and gloadtile_hi(), use new function check_nonpow2()
  (bit-twiddling) instead of loop
- Replace a couple of missed literals with CACHEAD_* enum labels

Factor out commonly occuring hictinting[]-accessing code into three functions.

Note: in polymer.c, this was buggy (but harmless) because .r is a char:
  if ((uint32_t)hictinting[MAXPALOOKUPS-1].r & 0xFFFFFF00) != 0xFFFFFF00)

Replace various GL rendering related literal flags with enum labels.

- pthtyp pth->flags bits
- Flags of the <dameth> argument of various functions
- hictinting[].f / gloadtile_hi() and daskinloader() <effect> arg bits
- hicreplctyp hicr->flags bits
- texcacheheader cachead.flags bits

Polymost: in NPOT wall ypanning "correction", behave like Polymer in one corner case.

Specifically, the handling of one-way walls ([1] in Mapster32) was slightly
different.
