ae429de8f6 video: GST_EXPORT -> GST_VIDEO_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

f4f3894836 video-scaler: Enforce same taps on Y and UV scalers for merged formats
Make sure we have the same number of taps for the Y and UV scalers so
that the scalers can be merged correctly.

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.

f29b966c79 video-converter: add fast-path scaler for some packed YUV formats
Add fast path scaling for YUY2 and other packed YUV formats. Add a new
method to merge the scalers of the Y and UV components into one scaler.
Add faster horizontal 2tap scaler.

ca2bd1cc6b video-scaler: rename resampler to video-resampler
Prefix the resampler with video-. It we would like to reuse the
resampler for audio later, we can copy/move it and deprecate this
one.

daf20d5e09 video-scaler: remove color range argument
We just need to clip to the format limits, if there is extra headroom in
the range we can use that without problems.

199fab4b06 video-scaler: add video scaler helper object
Add a video scaler object build on top of the resampler. It has
implementation to deal with interlaced video as well as horizontal and
vertical scaling functions.
