[Spice-devel] [PATCH spice-server 08/10] red_channel: add spice_channel_client_error

[Yonit Halperin]

spice_channel_client_error prints warning and shutdowns the
channel_client that hit the error.
This macro is useful for errors that are specific for one session
and that are unrecoverable only with respect to this session.
Prefer disconnecting a client over aborting when possible.
