04f0c40c74 fftools/ffmpeg_filter: add InputFilter private data 
Move InputFilter.frame_queue to it, which is not accessed outside of
ffmpeg_filter.

09dd9c5f41 fftools/ffmpeg_filter: add filtergraph private data 
Start by moving OutputStream.filtered_frame to it, which really belongs
to the filtergraph rather than the output stream.

38c937e8c4 fftools/ffmpeg: drop undocumented runtime debug-setting 
This feature is of highly questionable usefulness and - as the comment
in the code says - is not actually supported by the API.

0ed1eeb744 lavf/dv: use a more granular timebase for audio 
One that is fine enough to represent all DV audio sample rates. Audio
packet durations are now sample-accurate.

This largely undoes commit 76fbb0052d. To
avoid breaking the issue fixed by that commit, resync audio timestamps
against video if they get more than one frame apart. The sample from
issue #8762 still works correctly after this commit.

Slightly changes the results of the lavf-dv seektest, due to the audio
timebase being more granular.

c7a852b638 lavf/dv: do not set video timebase more than once 
Current code will call avpriv_set_pts_info() for each video frame,
possibly setting a different timebase if the stream framerate changes.
This violates API conventions, as the timebase is supposed to stay
constant after stream creation.

Change the demuxer to set a single timebase that is fine enough to
handle all supported DV framerates.

The seek tests change slightly because the new timebase is more
granular.
