Revert back to using a band-splitter to increase the HF response
...
Unfortunately the shelf filter causes issues due to the shelf gain magnitude
creating a varying phase offset. The splitter also creates phase offsets, but
it's consistent regardless of gain.

Simplify the BFormatDec upsampler
...
Since the only difference applied is a scalar on the high-frequency response, a
B-Format-to-B-Format transcode can be accomplished with a high-shelf filter. A
similar thing can be done with AmbiUpsampler, but only when outputing to
periphonic B-Format.

Make sure the OpenSL capture buffer queue has the correct size
...
The ring buffer size may round up and have more queueable elements than OpenSL
was allocated with, leading to errors when queueing those extra elements. Now
OpenSL allocates the same number of elements that can be written to the ring
buffer.

Fix the ringbuffer write limit
...
Previously it just limited the returned write space, irrespective of how much
had already been written. The buffer could still be filled up by doing multiple
writes. Now the size is limited by adjusting the read pointer by the real vs
limited difference when calculating the writable space.

Rename ALCdevice_struct and ALCcontext_struct
...
A (possibly contentious?) change in the public headers. Those names were never
part of any specification, and I don't know why the struct names differed from
the actual type name. But with C++, which takes the original struct declaration
as the original name, it was affecting the type's internal symbols.
This shouldn't affect user code since ALCdevice_struct and ALCcontext_struct
were never part of the spec. If issues arise from this change, it should be
reported.
