This macro will allow to share options between AVClasses without
having to redefine the option name (as is currently done) and will
also allow to share the AVClasses itself (which is possible now
that AVClass.child_class_next is gone).

Fixes trac issue #7473.
Removes encoder delay (skip samples) and writes remaining frame samples after EOF to get correct sample count.
Output is now accurate vs players that use Microsoft's codecs (Windows Media Format Runtime).
Tested vs encode>decode WMAv2 with MS's codecs and most sample rate/bit rate/channel/mode combinations in ASF/XWMA.
WMAv1 appears to use the same delay, from FFmpeg samples.

When a device is derived from a source device, there are at least 2
devices, and usually the derived device is the expected device, so let's
pick the last device if user doesn't specify the filter device with
filter_hw_device option
After applying this patch, the command below can work:
$> ffmpeg -init_hw_device vaapi=va:/dev/dri/renderD128 -init_hw_device
qsv=hw@va -f lavfi -i yuvtestsrc -vf
format=nv12,hwupload=extra_hw_frames=64 -c:v h264_qsv -y out.h264

This bug flew under the radar because, in practice, these values are
0-initialized for the first invocation. But for subsequent invocations
(with different h/v values), reading from the uninitialized parts of
`out` is undefined behavior.
Avoid this by simply adjusting the iteration range of the following
loops. Has the added benefit of being a minor speedup.

If we do not clear the enc_ctrl, we will reuse previous frames' data like FrameType.

When encoding yuva420 (alpha) frames, the vpx encoder uses a second
vpx_codec_ctx to encode the alpha stream. However, codec options were
only being applied to the primary encoder. This patch updates
codecctl_int and codecctl_intp to also apply codec options to the alpha
codec context when encoding frames with alpha.
This is necessary to take advantage of libvpx speed optimizations
such as 'row-mt' and 'cpu-used' when encoding videos with alpha.
Without this patch, the speed optimizations are only applied to the
primary stream encoding, and the overall encoding is just as slow
as it would be without the options specified.

It is a special BSF that is only available via the av_bsf_list-API;
it is not part of the list generated from the declarations in
bitstream_filters.c and therefore needn't have external linkage.
