fallbackswitch: Recheck active_sinkpad after schedule_timeout
`schedule_timeout` can synchronously call `handle_timeout` and change the
active pad. We need to update `is_active` afterwards.

After calling `schedule_timeout` with `end_running_time`, we used to
assume there was no pad switch and reset `switched_pad` immediately. If
the pad actually got switched, this would make us miss a sticky events
update.

fallbackswitch: Move active_sinkpad out of State into its own Mutex
As described in issue #200, we hold the srcpad's stream lock in some
situations where we notify the `active-pad` property.

If there's a handler installed it will most likely attempt to read the
property, which had to take the `state` lock. Another thread could
already be holding this lock and attempting to obtain the srcpad's
stream lock. This resulted in a deadlock.

To avoid this, move the `active_sinkpad` field into its own Mutex, which
we never hold for long.

385a983e5f fallbackswitch: Fix racy manual switching test
The element has a small race condition where it might output two buffers
with the same running time during e.g. a manual switch. In practice this
is not a problem, so the test takes this race into account.

4aa00c9eca fallbackswitch: Don't configure a framerate in the test

In addition also set durations on raw audio/video buffers based on the
caps if no duration is set.

930cc41aaa fallbacksrc: Don't forward manual flush events to downstream
fallbackswitch might forward flush event if it's for the currently
active pad. But forwarded flush event will be problematic in various
reasons and that's not a behavior we expected.

d3d98c73ca fallbacksrc: Connect to notify::active-pad after requesting pads
Requesting the first pad will emit the property because the first pad is
then selected. That will cause the callback to be called, which tries to
take the same mutex that is already locked during element setup and
causes a deadlock.

bd2ff494c7 fallbackswitch: Replace with priorityswitch
fallbackswitch now supports multiple sink pads, and on a timeout of the
active pad, it will automatically switch to the next lowest priority pad
that has data available.

fallbackswitch sink pads follow the `sink_%u` template and have
`priority` as a pad property.

4a54001aed fallbacksrc: Flush source before restarting on errors
It might still be blocked downstream for a while, e.g. in the clocksync.

Flushing does not cause any problems as fallbackswitch is not going to
forward it and will only unblock everything up to there.
