743f07062a 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.

b5c8aa745e vf_yadif: unset cur_buf on the input link. 
The buffer is stored internally, so this prevents it from being unreffed
automatically.

3124886554 lavfi: place x86 inline assembly under HAVE_INLINE_ASM. 
This allows compiling this code using compilers that do not understand

7155763b78 vf_drawtext: don't give up its own reference to the input buffer. 
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.

b7558ac293 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().
