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.

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.

decklink: Make sure our clock never returns NONE, always advances and does not jump when going from PAUSED to PLAYING
...
It basically behaves the same as the audio clocks.

decklinkvideo{sink,src}: Make elements more similar to the audio elements by enabling the video input/output only when getting the actual caps
...
This will also make it easier later to support caps changes and support
selecting the mode based on the caps if that should ever be implemented.

decklinkvideosink: Stop scheduled playback shortly in PAUSED->PLAYING if it was running already
...
This fixes handling of flushing seeks, where we will get a PAUSED->PLAYING
state transition after the previous one without actually going to PAUSED
first.

decklinkvideosink: Don't schedule too late frames in prepare()
...
Otherwise we will overflow the internal buffer of the hardware
with useless frames and run into an error. This is necessary until
this bug in basesink is fixed:

decklinkvideosink: Keep track of the time when we went to PLAYING for the external clock too
...
Otherwise we're adding an offset of the time the pipeline was in PLAYING
already to the running time when converting it to our internal clock.

decklinkvideosink: Get our own "start time" instead of the one of the pipeline
...
decklinkvideosink might be added later to the pipeline, or its state might
be handled separately from the pipeline. In which case the running time when
we (last) went into PLAYING state will be different from the pipeline's.
However we need our own start time to tell the Decklink API, which running
time should be displayed at the moment we go to PLAYING and start scheduled
rendering.
