Remove static_cast because protocol_negotiated() returns
NextProto.

We should remove the protocol_negotiated() method.

Nit: this method should be defined right after GetSSLCertRequestInfo
to match the declaration order in the .h file.

Done.
Done.
 
GetSSLCertRequetInfo is pure virtual but I moved this new method to the
appropriate place in the file.
