 Hi guys,

 Tor has its own hand-rolled timing-safe memcmp() which is nice, but
 Operating Systems like OpenBSD, NetBSD, and possibly others soon are
 starting to ship with a timing safe memcmp().

 On OpenBSD, it's called timingsafe_memcmp().

 Below is a patch that checks for it, and uses it if the host platform has
 a timingsafe_memcmp().
