[Mono.Security]: Add a few more 'Mono.Security.Interface' APIs.

The following general-purpose enums and exception helpers were moved
here from Mono.Security.NewTls.Interface, which is going away.

* Alert, CipherAlgorithmType, CipherSuiteCode, ExchangeAlgorithmType,
  HashAlgorithmType, TlsConnectionInfo, TlsException, TlsProtocolCode,
  TlsProtocols.

* TlsConnectionInfo has been merged into MonoTlsConnectionInfo.

Note that you may not use 'using' statements for both 'Mono.Security.Interface'
and 'System.Security.Authentication' due to conflicting types.  Use a prefix such as
"using MSI = Mono.Security.Interface;" or "using SSA = System.Security.Authentication;"
if you need both namespaces.
