Remove AL_SOFT_map_buffer from alffplay and add AL_SOFT_callback_buffer
...
The former doesn't really help too much since buffers still need to be
(re)filled and (de)queued individually. A callback buffer, on the other hand,
allows for greater efficiency since it just needs to write into a ring buffer
that the mixer will directly read from.

Restructure codec send/receive calls
...
In particular, after an initial fill of the codec's internal buffer, each
receive_frame call is followed by one or more send_packet calls. For
asynchronous codecs, this has the effect of letting the codec work while the
handler thread is waiting for an AVFrame structure to become available or
waiting for more decoded data to be needed. For synchronous codecs, this
makes the send_packet calls use up time that would be spent waiting.

Rework packet handling in alffplay
...
Turns out avcodec_send_packet is what can invoke the decode for serialized
codecs, so don't call that in the parse handler thread. The packet queue is
used to get the compressed data from the parse handler to the audio/video
threads.
Additionally, don't serialize the video frame preparation with the decode
thread.

Partially handle ambisonics in alffplay
...
This is currently really only applicable to Opus-encoded files. It assumes
AmbiX (SN3D normalization, ACN ordering) and only comes into play when the
channel layout is blank. FFmpeg/libavcodec doesn't have a way to detect
B-Format input or what normalization and ordering it uses. Note in particular
.amb files do not play correctly (libavcodec seems to apply a default channel
layout for 4-channel wav-type files, regardless of its channel mask value).
