9719b055c5 fallbacksrc: Retry fallback stream on errors too 
It was retrying but then nonetheless handling the error as fatal.

1d4d3e4cb0 build: Update versions to be 0.9.0-alpha.1 
0.9.0 is the next release, so we can't name things that already.

Also the version in meson.build was 0.13.0, which is completely wrong.

abf872130a fallbackswitch: fix gap processing regression 
This was broken by the rewrite, receiving gaps on the main pad
should let the position progress, reset timeouts and keep the main
pad active.

This picks the simplest solution, transforming gap events into GAP
buffers and letting them go through chain(), this achieves the desired
effect.

fallbackswitch: Reset timeout_clock_id on timeout 
We shouldn't leave the used clock ID around. Otherwise, we might never
schedule a new timeout from an inactive pad if the active pad doesn't
get a buffer.

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 
The tests assume that buffers have no known duration and would deadlock
otherwise because timeouts are scheduled to the end of a buffer.

617a2ef49e fallbackswitch: Clip buffers against the segment 
Also clip raw audio/video buffers according to the caps if they have the
relevant information in the caps, and drop raw audio samples if they're
outside the segment too.

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.

3de317b3c9 fallbacksrc: Don't panic when shutting down the source and there are source pad blocks but no actual source pads

Sebastian Dröge
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.
