range_validbuf - range check buffer

#include <libowfat/rangecheck.h>

int range_validbuf(const void* buf,size_t len);

range_validbuf does some basic plausibility checks on the buffer buf[0..len-1].

If the buffer is implausible (buf is NULL or buf+len has an integer overflow), return 0.

Otherwise, return 1.
