Removes definitions for (U)LLONG_MAX and (S)SIZET_MAX (#1877)
LLONG_MAX and ULLONG_MAX are defined in limits.h in C99. SIZET_MAX
should be SIZE_MAX, which has been around forever. SSIZET_MAX should
be SSIZE_MAX, which is defined whereever ssize_t is found. I've kept
the definition for SSIZE_MAX (renamed from SSIZET_MAX) for platforms
where ssize_T is not present (e.g., Windows).
