42959044ac lavfi/buffersrc: fix directly setting channel layout 
When setting the channel layout directly using AVBufferSrcParameters
the channel layout was correctly set however the init function still
expected the old string format to set the number of channels (when it
hadn't already been specified).

383057f8e7 lavfi: make ff_framequeue_skip_samples() more useful. 
Instead of just updating statistics and leaving the work to the
call site, have it actually do the work.

Also: skip the samples by updating the frame data pointers
instead of moving the samples. More efficient and avoid writing
into shared frames.

977fd88419 avfilter/formats: do not allow unknown layouts in ff_parse_channel_layout if nret is not set 
Current code returned the number of channels as channel layout in that case,
and if nret is not set then unknown layouts are typically not supported.

Also use the common parsing code. Use a temporary workaround to parse an
unknown channel layout such as '13c', after a 1 year grace period only '13C'
will work.

32c59a115d lavfi: do not call ff_filter_frame() with activate. 
avfilter_graph_request_oldest() does work that should be done by
either the filter or the application.

The principle of this function, calling ff_request_frame() from
outside the filter was always shaky. This version is less elegant
since it requires making special cases for each filter, but it
is more robust since it no longer calls ff_request_frame()
directly without notifying the filter.

Eventually, avfilter_graph_request_oldest() will be deprecated
for a function to just run the graph.
