	* CipherSuite.cs: Avoid creating a CryptoStream and a MemoryStream in
	EncryptRecord (removing the need to do a keysetup each time). Add
	helper methods to write inside byte buffers. Decrypt the data in
	place (without allocating new memory) as the result will always be
	smaller than the original. Avoid TlsStream in CreatePremasterSecret
	method. All HMAC access are done with the Negotiating parameters.
	* ClientRecordProtocol.cs: Set HandshakeState to None if we receive
	a HelloRequest during an existing session. Remove overidden method
	ProcessChangeCipherSpec. Skip memory allocation if possible.
	* Context.cs: Add new SecurityParameters for current, negotiating,
	read and write (actually only two different instance exists). Change
	readSequenceNumber and writeSequenceNumber to ulong to match specs.
	Remove all properties that are moved/replaced with SecurityParameters.
	Added methods to Start and End a switch of the security parameters.
	* RecordProtocol.cs: Add code to ProcessChangeCipherSpec (not abstract
	anymore). Remove ReadShort and it's use. Deal with null alerts in
	SendAlert method (internal error). Change code to deal with
	SendChangeCipherSpec inside an existing (encrypted) session. Update
	Cipher to use the correct one (mostly Read.Cipher or Negotiating.Cipher
	for ProcessCipherSpecV2Buffer method).
	* SecurityParameters.cs: New. Deal with all parameters that changes
	between negotiations.
	* ServerRecordProtocol.cs: Remove method ProcessChangeCipherSpec.
	* SslCipherSuite.cs: Don't use TlsStream when computing MAC. Set the
	MAC keys to the Negotiating security parameters.
	* SslClientStream.cs: Change calls from Cipher to Negotiating.Cipher.
	* SslServerStream.cs: Change calls from Cipher to Negotiating.Cipher.
	Remove debugging dead code (DateTime).
	* SslStreamBase.cs: Change calls from Cipher to Current.Cipher. Reuse
	existing memory buffer.
	* TlsCipherSuite.cs: Don't use TlsStream when computing MAC. Set the
	MAC keys to the Negotiating security parameters.
	* TlsClientSettings.cs: Comment code cause compiler warnings.
	* TlsStream.cs: Avoid/reduce memory allocations when reading or
	writing small integer values to the stream.

In Mono.Security.Protocol.Tls.Handshake.Client:
2006-09-11  Sebastien Pouliot  <sebastien@ximian.com>

	* TlsClientFinished.cs: Use Write.Cipher instead of Cipher. Remove
	usage of TlsStream in ProcessAsSsl3.
	* TlsClientKeyExchange.cs: Use Negotiating.Cipher instead of Cipher.
	Refactor to avoid code duplication between SSL3 and TLS.
	* TlsServerCertificate.cs: Use Negotiating.Cipher instead of Cipher.
	* TlsServerFinished.cs: Use Current.Cipher instead of Cipher. Use
	Compare to test client and server digests equality. Remove usage of
	TlsStream in ProcessAsSsl3.
	* TlsServerHello.cs: Use Negotiating.Cipher instead of Cipher. Remove
	usage of TlsStream to reduce memory allocations. Remove method
	CompareSessionId and use the new base class Compare method instead.

	* HandshakeMessage.cs: EncodeMessage is called very often so we avoid
	many allocations by not creating a TlsStream and by not calling
	WriteInt24 (IPAddress.HostToNetworkOrder and BitConverter.GetBytes).
	We also cache the encoded result to avoid computing/allocating the
	encoded message twice (in most cases) for the handshake. Added a
	Compare static method to compare byte arrays (easier to step out when
	debugging).

In Mono.Security.Protocol.Tls.Handshake.Server:
2006-09-11  Sebastien Pouliot  <sebastien@ximian.com>

	* TlsClientCertificate.cs: Use Negotiating.Cipher instead of Cipher.
	Fix reading the message length if it's zero (in that case it's not
	present two times).
	* TlsClientFinished.cs: Use Current.Cipher instead of Cipher. Use
	Compare to test client and server digests equality.
	* TlsClientHello.cs: Use Negotiating.Cipher instead of Cipher.
	* TlsClientKeyExchange.cs: Use Negotiating.Cipher instead of Cipher.
	* TlsServerFinished.cs: Use Current.Cipher instead of Cipher.
	* TlsServerHello.cs: Use Negotiating.Cipher instead of Cipher.
