Simon L. B. Nielsen 6a599222bb 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superseded with OpenSSL 0.9.8m's RFC5746 'TLS renegotiation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.
