992101f82a videoencoder: Keep sticky events around when doing a soft reset 
The current code will first discard all frames, and then tries to copy
all sticky events from the (now discarded) frames. Let's change the order.

5d456c7adc video-frame: fix height/width assertions 
As commit 274984e8 states:
When doing CROP META it is expected that the width and/or height
in the GstVideoMeta is bigger or equal to the caps negotiated size.

3cd2eb5847 video-converter: fix border handling of YUY2 and friends 
Don't draw the border in groups of 4 pixels for YUY2 but instead in
groups of 2 with alternating U and V. This avoids a crash on odd width
borders.

0d333d8d44 video-converter: add table based matrix8 implementation 
Based on patch from Mozzhuhin Andrey <nopscmn at gmail.com>

Add a table based matrix8 multiplication implementation. The algorithm
does not do any clipping so we need to make sure we never call this on
input that might need to be clipped. In general, this algorithm is
2 times faster than the orc optimized one and would be chosen for all
RGB -> YUV conversions and some YUV->YUV and RGB->RGB conversions.

cdd86d025a video-scaler: add 2d scaler 
Make a convenience function that combines 2 scalers to perform a 2d
scale. This removes quite a bit of overhead in method calls when doing a
typical scale and it also can reuse a piece of unused memory in the
vertical scaler.
Use the 2d scaler in video-converter and remove the other scalers and
temp memory.
