Hi,

Thanks to recent work by Kevin, it becomes possible to run HMP/QMP commands i=
n a
coroutine. The screendump command is a good target, as it requires to re-enter
the main-loop in ordre to flush the display, and write to file. Ideally, IO
would be done with a non-blocking fd, however it's not currently enabled. This
is left for a future work.

v2:
 - change summary to not falsly claim non-blocking write support
 - code styles fixes
 - rebased, add reviewed-by tags

Marc-Andr=C3=A9 Lureau (3):
  coroutine: let CoQueue wake up outside a coroutine
  console: modify ppm_save to take a pixman image ref
  console: make QMP/HMP screendump run in coroutine
