This changes how NTSC VANC is extracted from the buffer. In NTSC the vanc data
is interleaved between luma and chroma, and not just the luma as in high
definition resolutions.

In my testing this allows a decklink card encoding valid NTSC closed
captions to pass the caption data to the x264 encoder.

Updated with reviews from Devin Heitmueller and Marton Balint.

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.

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.
