In the past XvMC forced simple_idct since
it was using FF_IDCT_PERM_NONE.
However now we have SIMD variants of simple_idct that
are using FF_IDCT_PERM_TRANSPOSE and if they are selected
XvMC would get coefficients in the wrong order.
The patch creates new FF_IDCT_NONE that
is used only for this kind of hardware decoding
and that fallbacks to the old C only simple idct.

Can be tested via the following command:
./ffmpeg -i foo.ts -f decklink -vcodec v210 'DeckLink Duo (1)'
Note that the 8-bit support works as it did before, and setting
the pix_fmt isn't required for 10-bit mode. The code defaults to
operating in 8-bit mode when no vcodec is specified, for backward
compatibility.

Add support for enumerating the sources/sinks via the ffmpeg
command line options, as opposed to having to create a real pipeline
and use the "-list_devices" option which does exit() after dumping
out the options.
Note that this patch preserves the existing "-list_devices" option,
but now shares common code for the actual enumeration.

This reverts commit c2d155e11e.
GCC 6 incorrectly passes the configure test and then logs many warnings
of the form:
src/libavformat/dump.c: At top level:
cc1: warning: unrecognized command line option ‘-Wno-bool-operation’
The initialisation should be common. For libmfx, it was previously
happening in the derivation function and this moves it out. For VAAPI,
it fixes some failures when deriving from a DRM device because this
initialisation did not run.
