improve buf_cmp and buf_cmp_mask helpers

Rewrite buf_cmp to use memcpy for bulk of comparison.  Add static
helper to perform comparison of trailing byte, which uses another
static helper to perform a maksed comparison.  The masked comparison
helper is used by the buf_cmp_mask to simplify its loop.
Improve types to use void *, unsigned, and return bool.
