Clang applies the missing-prototypes warning on C++ files, whereas
gcc only applies it to C.  As a result, the decklink_common.cpp file
fails to build because of missing prototypes in DecklinkDispatch.cpp
(which is #included by decklink_common.cpp).

We don't want to change the actual Blackmagic SDK sources, so
suppress the warning just for that one #include.

When building with Clang, the following warning is shown:

warning: struct 'IDeckLinkVideoFrame' was previously declared as a
class [-Wmismatched-tags]

The function incorrectly casts IDeckLinkVideoFrame as a struct
instead of a class pointer.

The libavformat API is not suitable for exporting output devices as muxers.
Some practical problems are e.g. lack of timing/synchronization mechanisms
or interaction with output-specific features.

It should be sys/soundcard.h nowadays.

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.

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.
