Merge OpenSSL 0.9.8m into head.
This also "reverts" some FreeBSD local changes so we should now
be back to using entirely stock OpenSSL. The local changes were
simple $FreeBSD$ lines additions, which were required in the CVS
days, and the patch for FreeBSD-SA-09:15.ssl which has been
superseded with OpenSSL 0.9.8m's RFC5746 'TLS renegotiation
extension' support.
MFC after: 3 weeks
