[Spice-devel] [PATCH spice-server v2] Move channel registration to constructed vfunc

[Jonathon Jongsma]

For the Display Channel and the Cursor channel, move the call to
reds_register_channel() to the _constructed() vfunc rather than calling
it explicitly from RedWorker. This matches what other channels do.
---
Changes in v2:
 - remove cursor channel registration in stream device

Note that I didn't implement a couple other suggestions from Frediano's first review. Reference
earlier email reply for justification.
