Handles decoding of new VP9 profiles 1-3 with different color sampling
and bit-depths.

For high bitdepth (profiles 2 and 3) support, we currently need to link
with the highbitdepth branch of libvpx with --enable-experimental
and --enable-vp9-high config options on. But eventually this branch will
be merged into master, whereafter to enable high bitdepth
support you will need to link with libvpx with configure option
--enable-vp9-highbitdepth on.

bmp pipe needs the bmp parser which is not bug free and should thus not be favored
over the bmp image2 demuxer
that also means this change could be reverted in case bmp pipe is improved so it
handles all single bmp images correctly
