Ability to specify allowed ciphersuites based on the protocol version.

The ciphersuites parameter in the ssl_session structure changed from
'int *' to 'int *[4]'.

The new function ssl_set_ciphersuite_for_version() sets specific entries
inside this array. ssl_set_ciphersuite() sets all entries to the same
value.
