0043db2967 doc/filters: move *setpts and *settb filters to the multimedia filters section
Since audio and video filters are explained together and share most code,
the multimedia filters section seems more fitting.

48d116400c lavfi: add framestep filter
This filter is inspired upon libmpcodecs/vf_framestep.c, by Daniele
Forghieri.

Only-keyframe output is not supported, since that feature can be achieved
through the more versatile select filter.

70d71b5801 af_asyncts: add first_pts option
This allows for padding/trimming at the start of stream. By default, no
assumption is made about the first frame's expected pts, so no padding or
trimming is done.

4ce87ecf2a asrc_flite: do not crash on multiple instances.
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.

32390d6767 lavfi: move movie and amovie to a "multimedia sources" section
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.

82ecae8a70 lavfi: add alphaextract and alphamerge filters
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.
