0e3bfbd996 video-scale: combine adds when max_taps equals combine size 
When the amount of pixels/lines matches the amount we can combine,
combine the adds and multiplies and do the scale as a separate
operation.

721bbcad34 video-resampler: Fix lanczos parameters for variable taps 
when using variable taps and when we are limiting the number of taps,
recalculate the lanczos parameters to match the clamped value.

e5c6f59140 playsink: Reset mute property of the sink to playsink's value when setting up the audio chain 
Otherwise the following can happen:
1. set mute=true
2. play media1 (Ok)
3. play media without audio (audiochain removed)
4. play media2 (audiochain created, mute=*false*)

for both interlaced and progressive frames and switch between them

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.

Refactor GstVideoInfo init, make function to set default colorimetry.
Call fill_planes after we configure the GstVideoInfo with parameters
from the caps.
The size of the chroma planes for interlaced vertically subsampled
formats needs to be rounded up to 2, we have 2 fields with each
the same anount of chroma lines.
