ssl: Handle really big handshake packages
If a handshake message is really big it could happen that the ssl
process would hang due to failing of requesting more data from the
socket. This has been fixed.
Also added option to limit max handshake size. It has a default
value that should be big enough to handle normal usage and small
enough to mitigate DoS attacks.
