Norman Feske 09461c51bd capture_session: capture stop/wakeup protocol
With this change, a client (i.e., display driver) can register
a wakeup signal handler to be notified on the arrival of new data to
capture. The signal is delivered only when the client has stopped
capturing. The client propagates this condition to the server using
the new 'capture_stopped' RPC call.

This change in principle enables a display driver to suspend its
periodic mode of operation after a few frames without capturing any
new data. As the first driver, the fb_sdl driver has been adapted to
the new protocol. This change not only eliminates the driver's CPU
load when idle, it also reduces the latency of sporadic output
because the response to such GUI updates is no longer bound by a
fixed periodic interval.

Issue #5344
