* Removed DataTypeCode from ChannelDataEventArgs, as this is specific to extended data. * Large set of optimizations in receive and send of SSH messages: - removed several buffer copies - modified most of the SSH messages to allow the size of the message to be calculated in advance to eliminate need to resize buffer. - added Compress(byte[] data, int offset, int length) overload to Compressor to compress part of a given buffer thereby avoiding need for buffer copy. - added Encrypt(byte[] data, int offset, int length) overload to Cipher to encrypt part of a given buffer thereby avoiding need for buffer copy. * SshData: - SshData.GetBytes uses a SshDataStream which has a capacity that (in almost all cases) matches the size of the SSH message. - Added a Load(byte[] value, int offset) overload. - Added a LoadBytes(byte[] bytes, int offset) overload. - Added a Write(byte[] data) overload. - Added a Write(byte[] buffer, int offset, int count) overload. * Added SendData(byte[] data, int offset, int size) overload to Channel to allow sending part of a given buffer. This avoids a buffer copy in ScpClient, SftpClient, Shell, ChannelDirectTcpip, ChannelForwardedTcpip. Fixes issue #1516. All optimization changes above are only active when the TUNING conditional compilation symbol is defined. By default, this symbol is defined.
