The voice register functions return the same voice structure
upon multiple registration. It causes us two problems:
If we delete a voice without deregistering it, it leaves
a dangling pointer inside the library.
If we delete or unregister a voice at uninit, it may still
be in use by another instance of the filter.
The second problem is solved by keeping an usage counter inside
asrc_flite. This is not thread-safe, but neither is flite itself.
Since the recent changes, movie and amovie are able to deal with more
than one type of stream, so they should be categorized as "multimedia
sources" rather than audio/video sources.

These filters are designed for storing and transmitting video sequences
with alpha using higher-efficiency codecs such as x264 which don't
natively support an alpha channel. 'alphaextract' takes an input stream
with an alpha channel and returns a video containing just the alpha
component as a grayscale value; 'alphamerge' takes an RGB or YUV stream
and adds an alpha channel recovered from a second grayscale stream.

Directly forwarding the input buffer to the next filter means that
drawtext no longer owns any references to it and thus shouldn't refer to
it in any way.
This one is tricky. Consider a graph with two sink links, A and B.
request_oldest() requests on A, and A returns EOF. This EOF causes
a filter to flush pending frames to B; they are unrequested.
Then request_oldest() moves on to B, and B returns EOF.
movie currently forwards EOF (or begins looping) immediately upon
reaching the last packet in the input stream, which can leave frames in
the decoder. This change first tries to read any remaining packets from
the decoder before forwarding EOF.

Use the init_opaque callback for the purpose.
Fix regression introduced in a5e8c41c28. In particular, fix lavfi
device in case a conversion to the supported (packed) formats is needed.
This will be used by filters which require an opaque field to be passed
in input. Should be required only for filters which imply a programmatic
use.
This is possibly a temporary solution, to be removed when we'll have a
clearer and better agreememnt of how/if to pass binary data for
initializing a filter.

Input on/off state can change in request_samples(), which can result in
a state where only the first input is active. get_available_samples()
will then return 0, and request_frame() will fail with EAGAIN even
though there is data on the single active input.
Take this into account and check the number of active inputs again after
calling request_samples().

Add request_frame() which checks the black duration when the end of the
stream is signalled. Allow to detect black video segments at the end of
the stream.
Note that the reported last black video segment duration is not very
accurate, since we still miss the duration information in the video
buffer.
Address trac ticket #1470.
It's redundant, since the input buffer is passed as a parameter to the
filter_samples() callback, and can lead to stale pointers remaining on
the link.
