Convert the alpha value to 0->255 when setting and to 0->256 when using as
a scaling factor. This makes sure we can reach the full opacity value of 0xff in
all cases.
Link to properties. Correct titles for examples. Document a few trivial cases. Keep lists in section file and docs/plugins/Makefile.am alphabetically ordered.

* gst/alpha/gstalpha.c: (gst_alpha_class_init), (gst_alpha_init),
(gst_alpha_set_property), (gst_alpha_get_property),
(gst_alpha_chroma_key_ayuv), (gst_alpha_chromakey_row_i420):
Try to skip pixels or areas that are too dark or too bright for us to do
meaningfull color detection.
Added properties to control the sensitivity to light and darkness.
Added some small cleanups. Fixes#512345.
Original commit message from CVS:
* gst/alpha/Makefile.am:
* gst/alpha/gstalpha.c:
Re-write the 'alpha' plugin to be BaseTransform based, simplifying
some stuff, and making buffer-alloc and resizing work automatically.
No longer crashes on odd frame widths and heights, although there
seems to be a disagreement with ffmpegcolorspace about what size
an AYUV frame with odd height should be.

Make the various properties of 'alpha' controllable. This allows doing
niceties like fade-in/fade-out.

Detect RGBA/BGRA correctly on little endian systems.
Original commit message from CVS:
* gst/alpha/gstalphacolor.c: (gst_alpha_color_base_init),
(gst_alpha_color_transform_caps), (gst_alpha_color_set_caps):
Double-check that RGB input caps are really RGBA caps (apparently
the core doesn't always catch it if those caps aren't a subset of
our template caps, also see #421543). Fixes#429319 in a way.
Also, don't leak the pad template in the transform_caps function.
