cba63b6d43 Added fallback to CMDTYPE_STREAM_SURFACE_BITS
Since our samples were incorrect, add a fallback with a log warnings
to the old CMDTYPE_STREAM_SURFACE_BITS by default behaviour.

88ad9ca56b Fix sending/receiving surface bits command.
* Pass on proper command type to application
* On send let the server implementation decide to send
   2.2.9.2.1 Set Surface Bits Command (TS_SURFCMD_SET_SURF_BITS) or
   2.2.9.2.2 Stream Surface Bits Command (TS_SURFCMD_STREAM_SURF_BITS)
Thanks to @viniciusjarina for tracing the issue down.

8e55c44088 tpkt_ensure_stream_consumed now more verbose.
tpkt_ensure_stream_consumed now writes the function it was called
from to the log. This should help identify areas the check failed.

17e0d25104 dynvc/client: fix and improve channel closing code
- fixed and consolitate the duplicated code for sending the
  CLOSE_REQUEST_PDU to the server into dvcman_close_channel
- call dvcman_close_channel if a dynamic channel plugin fails
  to process the received channel data
- rdpegfx: don't try to remove a non-existing cache entry,
  return an error instead which now will close the channel, as
  expected by Microsoft's windows protocols test suite
