Subject: [PATCH] ipc: put playback core to sleep while dequeuing commands

Happens to fix #1581 due to an unfortunate interaction with the way the
VO does not react to commands for a while if a video frame is queued.
Slightly improves other situations as well, if the client spams mpv with
commands during playback.

(cherry picked from commit 32b56c56bad78d8d3038361aef6f36ad9cabebb0)
