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.

The string is allocated with CFStringGetCString but was being
deallocated with free(), which would intermittently result in
a segmentation fault.  Use the correct function for freeing the
allocated CFString.

In case we are short of queued buffers, at first v4l2_buffer was enqueued to kernel so it's not owned by
user-space anymore. After that it's timestamp field was read, but it might be overwritten by driver at
that moment. It resulted in invalid timestamp sometimes.

The definitions are different: 3:3:2 vs 2:3:3.

The planes are unlikely to be contiguous, assuming they are results in
very broken output.  (Tested with NV12/NV16 on Rockchip.)

All DRM formats are defined in terms of little-endian words, so RGB formats
like XRGB actually have the elements in the opposite order order in memory
to the order they are in the name.

This does not affect YUYV and similar YUV 4:2:2 formats, which are in the
expected order.

DRM_FORMAT_R8 was added in libdrm 2.4.68.
DRM_FORMAT_R16 was added in libdrm 2.4.82.

QTKit has been deprecated in favor of AVFoundation for years, and we
have an avfoundation input device.

This code is disabled since 2012. V4L1 was dropped from the kernel more
than 10 years ago.

sndio is already autodetected, this commit makes sure
--disable-autodetect actually disable it unless --enable-sndio is
specified.

alsa libs are already autodetected, this commit makes sure
--disable-autodetect actually disable it unless --enable-alsa is
specified.
