Replace the sinc4 resampler with cubic
...
Turns out the C version of the cubic resampler is just slightly faster than
even the SSE3 version of the FIR4 resampler. This is likely due to not using a
64KB random-access lookup table along with unaligned loads, both offseting the
gains from SSE.

Avoid the modulated output tap for late reverb
...
And fix the output filtering. The modulation code is still there since it's
(probably) technically correct, but the interaction with the feedback loop and
filtering on the output caused improper behavior which needs to be sorted out.

Avoid dereferencing a NULL pointer

Even though it's taking the address of a member, it's still technically a

Improve the alffplay queue for FFmpeg's send/receive API
...
The packet handling thread now calls avcodec_send_packet to give compressed
data to libavcodec, while the audio/video threads call avcodec_receive_frame to
handle decoded frames. The packet thread still maintains local queues for each
stream to avoid starving an A/V thread when the other doesn't want another
frame yet.
