Add experimental support for 24-bit, dual-ear HRTFs
...
Currently makehrtf only handles 24-bit output, not dual-ear, and only when
given the --experimental switch. Files produced this way will not be guaranteed
future compatibility. When the mhr format is also updated with multi-distance
measurements, the experimental switch can go away.

Replace makehrtf's dither
...
This uses a custom RNG instead of relying on the system-dependent rand(). It
also removes the high-pass/noise-shaping, to flatten the noise floor.

Add a front-stablizer config option for surround sound modes
...
This improves a stereo (front-left + front-right) sound "image" by generating a
front-center channel signal. Done correctly, it helps reduce the comb effects
and phase errors associated with using only two speakers to simulate center
sounds.
Note that it shouldn't be used if the front-center channel is already included
in the positional audio mix (the dialog effect is okay). In general, it may
actually be better to exclude the front-center channel from the positional
audio mix and use this to generate front-center output.

Update default 5.1 and 6.1 coefficients to exclude front-center
...
Not all speaker kits have a front-center speaker capable of outputing full-
range content. It's best to err on the side of caution and not include front-
center for normal positional sound by default, leaving it instead for the
dedicated dialog effect.

be used for positional sounds, only the dedicated dialog effect.

Rename the OpenAL target if also building the router
...
This is rather ugly, but it's necessary to get a proper export configuration.
The issue was that the main OpenAL target library name is set to soft_oal when
the router is being built, which is incorrect for the exported config library.
Exporting the router would have the incorrect name of OpenAL::Router.
So this change has the router use the OpenAL target name when it's built, which
is good since it will have the standard OpenAL lib name for apps to link to and
get the OpenAL::OpenAL export name. The main library's target name is changed
in this case to avoid conflicts.
