a3da634db6 video-format: improve unpack i420
unpack_i420 does not need extra code to handle odd widths, the orc code
already handles it fine.

35f6259b24 decodebin: Analyze source pad before setting to PAUSED for 'simple demuxers'
Before we were setting them to PAUSED and (much) later connecting to
their source pad caps notify signal.

There was a race where that demuxer was pushing a caps and later a buffer
on its source pad when we were not even connected to its source pad caps notify
signal leading to decodebin missing the information and not keeping on
building the pipeline on CAPS event thus the demuxer was posting an ERROR
(not linked) message on the bus. This need to be done for 'simple
demuxers' because those have one ALWAYS source pad, not like usual demuxers
that have several dynamic source pads.

A "simple demuxer" is a demuxer that has one and only one ALWAYS source
pad.

68edf0ebd6 decodebin2: Take STREAM_LOCK before sending sticky events.
There was a race where:

1) we would put the element to PAUSED
2) It would get data sent to it from upstream
3) It would thus send caps
3) caps_notify_cb would continue autoplugging
4) caps would flow downstream, the last pad would get exposed
5) we were still not done sending the sticky events

Taking the stream lock on the new element's sinkpad and only
releasing it when sticky events have all been sent prevents
the caps from reaching the source pad of the element before
we're all set.

7b7270ecff video-resampler: add option to limits taps
Add an option to limit the number of taps to use in automatic mode. The
problem is that for lanczos, we might use more taps than what we can
handle with the current precision.
Rework the other options a little to make it nicer to set defaults.

cefc518494 videorate: Operate in a zero-latency mode if drop-only is set to TRUE
There's no reason why we would have to wait for the next buffer to decide
whether to output the current one or not. We just have to check if the
current one is earlier than our expected next time, which is the previous
frame timestamp plus the expected frame duration.
