cleanup: C99 and vertex array comments

GPU_buffer no longer has a fallback to client vertex arrays, so remove
comments about it.

Changed a few internal structs/function interfaces to use bool where
appropriate.

Use for-loop scope and flexible declaration placement. PBVH does the
same thing but needs ~150 fewer lines to do it!

The change to BLI_ghashIterator_init is admittedly hackish but makes
GHASH_ITER_INDEX nicer to use.
