decklink: Add a clock epoch that is used as offset whenever restarting the clock
...
Otherwise we're going to return times starting at 0 again after shutting down
an element for a specific input/output and then using it again later.

decklinkvideosrc: fix mode autodetection
...
The autodetection mode was broken because a race condition in the input mode
setting. The mode could be reverted back when it was replaced in
the streaming thread by the old mode in the middle of mode changed callback.

decklink: Reset the clock calibration when unsetting the master clock
...
Otherwise the old calibration will stick around for the next time we use it,
potentially giving us completely wrong times.

decklinkvideosrc: Apply the diff between element and pipeline "base" time in all cases
...
Even if both clocks have the same rate, we need to apply this diff. Only when
it's the same clock we don't, as it's our clock then.

decklinkvideosrc: Add the diff between the pipeline base time and when we start to play
...
Add the diff between the external time when we went to playing and
the external time when the pipeline went to playing. Otherwise we
will always start outputting from 0 instead of the current running
time.

decklinkvideo{src,sink}: Sample the internal clock immediately after starting the device
...
Otherwise we might stay at 0.0s for too long because we will take the first
timestamp we ever see as 0.0... which will be after we started the device.

decklink{audio,video}src: Take the capture times from the pipeline clock
...
Not from the decklink clock. Both will return exactly the same time once the
decklink clock got slaved to the pipeline clock and received the first
observation, but until then it will return bogus values. But as both return
exactly the same values, we can as well use the pipeline clock directly.

decklink{audio,video}sink: Only start scheduled playback once both sources are ready and we are in PLAYING
...
Otherwise we might start the scheduled playback before the audio or video streams are
actually enabled, and then error out later because they are enabled to late.
We enable the streams when getting the caps, which might be *after* we were
set to PLAYING state.

decklinkvideosrc: Post LATENCY message when the mode changes

Different modes have different framerates, and thus different latencies. We
might need to reconfigure the latency of the pipeline.
