sndio: Support more than 2 channels

5cffe7e50a sndio: Support more than 2 channels 
So far the sndio backend only supports Mono and Stereo, but sndio
supports up to 16 channels (64 in their current git code).
This adds support for all the openal-soft formats (DevFmt*).
I tested this on Linux with 5.1 surround speakers.

200c164d78 Improve HRTF delay handling 
Ensures source-level HRTF, the dry mix, and direct output all align properly,
and simplifies adding the delay in the direct mix output.

825206bfa2 Apply the ambisonic HF scaling in real-time with HRTF 
Rather than applying the HF scale to the IRs necessitating them to be truncated
along with increasing the IR size, it can be applied to the input signal for
the same results. Consequently, the IR size can be notably shortened while
avoiding the extra truncation. In its place, the delayed reversed all-pass
technique can still be used on the input for maintaining phase when applying
the bandsplit/hfscalar filter to the input signal.

463591663c Check that aligned_alloc is available with cmake 
Some compilers support C++17 even on targets that lack required functions.
Projects that want to force C++17 will then run into a problem with
std::aligned_alloc not existing on those targets, so it needs to be explicitly
checked for. The alternative is to simply never use it even when it would be
available.

36aebbb6ae Include the existing direct signal in the UHJ delay 
So any direct_channels sources and normal panned sources remain aligned, and
the reported latency is accurate.

48fbad9836 Slightly improve the Hann windows 
There's no need to include the 0 terms on the ends since they'll never
contribute a sample. So extend the width to have the 0 terms just outside the
window where it wouldn't contribute anyway.
