swscale: Introduce a helper to identify semi-planar formats
...
This cleans up the ever-more-unreadable list of semi-planar
exclusions for selecting the planar copy wrapper.

swscale: Add p016 output support and generalise yuv420p1x to p010
...
To make the best use of existing code, I generalised the wrapper
that currently does yuv420p10 to p010 to support any mixture of
input and output sizes between 10 and 16 bits. This had the side
effect of yielding a working code path for all yuv420p1x formats
to p01x.

swscale: use dithering in DITHER_COPY only if not set -sws_dither none
...
This patch uses dithering in DITHER_COPY macro only if
it was not used option '-sws_dither none'.
With option '-sws_dither none' it uses downshift.
For human eye dithering is OK, for video codecs not necessarily.
If user don't want to use dithering, we should respect that.

The rationale is that you have a packed format in form
<greyscale sample> <alpha sample> <greyscale sample> <alpha sample>
and shortening greyscale to 'G' might make one thing about Greenscale instead.
An alias pixel format and color space name are provided for compatibility.
