* 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.

* Str.c: Use asprintf() instead of rolling our own printf string
length detection.
* cookie.c: Pass the char pointer in the string struct to printf %s
instead of the string struct itself.
Print time_t using %lld instead of %ld to allow for 64-bit time_t.
* main.c: Print a long int using the correct format specifier.
* map.c: Print size_t using the correct format specifier.
