obstack: avoid potentially-nonportable function casts * lib/obstack.c (CALL_CHUNKFUN, CALL_FREEFUN): Remove, replacing with ... (call_chunkfun, call_freefun): New static functions. All uses changed. Avoid potentially-nonportable casts. (chunkfun_type, freefun_type): Remove typedefs; no longer used. (_obstack_begin_worker): Omit last two args, since they rely on potentially-nonportable casts. All callers changed. * lib/obstack.h (_OBSTACK_CAST): New macro. Use it everywhere the old API used a potentially-nonportable cast. The new API doesn't cast. (struct obstack): Use unions rather than requiring potentially-nonportable casts. (obstack_chunkfun, obstack_freefun): Return void.
