f0726f471f Use float formats in examples/alstreamcb 
libsndfile apparently has issues reading floating-point wave files as 16-bit
samples (produces silence). Even on other file formats, reading float samples
as integer samples has no over/underflow protection, so this is better for
those formats too.

c993ade9bf Support B-Format amb file IRs in alconvolve 
Be aware this requires proper header data (a WAVE_FORMAT_EXTENSIBLE format with
the proper integer or float B-Format sub-format GUID). A normal 4-channel wave
file will not be recognized, since it's indistinguishable from quadrophonic.

These would be better served with a proper debug API, rather than a general

8554e6cde2 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.

9959d661a0 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.
