Add overflow detection
Origin: http://marc.info/?l=openbsd-ports&m=142090828929750&w=2 * main.c: Call exit(1) when out of memory to avoid dereferencing null pointers when gc's malloc fails. * alloc.h: Replacements for w3m's allocation macros which add overflow detection and concentrate the macros in one file. * indep.h, libwc/charset.c, libwc/status.c, matrix.c: Use the overflow-detecting allocation macros from alloc.h.
