lavfi: better channel layout negotiation
...
Allow substitution of channel pairs in the input for nearby channel pairs in
the output in order to get a closer match. Also weigh LFE channel mismatch
differently to favor matching the same layout without LFE over one less
channel with LFE.

af_amix: avoid spurious EAGAIN.
...
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().
