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.

Use linear interpolation for reverb modulation
...
The core LateReverb_* functions are explicitly written out now, since the
tapping and blending done by the Faded version is a bit more complex and it's
not so easy to ensure proper optimizing on the Unfaded version.

Don't offset the chorus/flanger delay and LFO

The delay being added to the scaled LFO will ensure a proper positive result
regardless.

Use a single delay line for chorus feedback on a fixed tap
...
The outputs themselves use a variale-delay tap, but using a separate fixed-
delay tap on the feedback helps improve the perceived "wobble" with sustained
notes. This also applies to the flanger effect.

Allow storing multiple buffers in a ALbufferlistitem
...
This will be to allow buffer layering, multiple buffers of the same format and
sample rate that are mixed together prior to resampling, filtering, and
panning. This will allow composing sounds from individual components that can
be swapped around on different invocations (e.g. layer SoundA and SoundB on one
instance and SoundA and SoundC on a different instance for a slightly different
sound, then just SoundA for a third instance, and so on). The longest buffer
within the list item determines the length of the list item.
More work needs to be done to fully support it, namely the ability to specity
multiple buffers to layer for static and streaming sources. Also the behavior
of loop points for layered static sources should be worked out. Should also
consider allowing each layer to have a sample offset.
