add stream report messages

Browse Source 
If the server & client support SPICE_DISPLAY_CAP_STREAM_REPORT,
the server first sends SPICE_MSG_DISPLAY_STREAM_ACTIVATE_REPORT. Then,
the client periodically sends SPICE_MSGC_DISPLAY_STREAM_REPORT
messages that supply the server details about the current quality of
the video streaming on the client side. The server analyses the
report and adjust the stream parameters accordingly.
