Antonio Nino Diaz aa050a7bdb stdlib: Import timingsafe_bcmp() from FreeBSD ...

Some side-channel attacks involve an attacker inferring something from
the time taken for a memory compare operation to complete, for example
when comparing hashes during image authentication. To mitigate this,
timingsafe_bcmp() must be used for such operations instead of the
standard memcmp().

This function executes in constant time and so doesn't leak any timing
information to the caller.
