LZ4 compression is now available at the Spicevmc channel

Enterprise / Virtualization / SPICE - snir sheriber [redhat.com] - 13 June 2016 17:12 UTC

Compressed message type is CompressedData which contains compression type (1 byte) followed by the uncompressed data size (4 bytes - exists only if data was compressed) followed by the compressed data

If SPICE_USBREDIR_CAP_DATA_COMPRESS_LZ4 capability is available && data_size > COMPRESS_THRESHOLD && !AF_LOCAL data will be sent compressed otherwise data will be sent uncompressed (also if compression has failed)

Update the required protocol to 0.12.12
