6eadccc99d 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.

8a735d0ba9 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.

e5431bbef7 Print an error if the input channel isn't in the device 
Rather than the other way around, if a device channel isn't in the channel map.

de51ba088e 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.

to be concerned.

0135ddc2e5 Scale the source volume by +3dB for a full spread 
This effectively turns a full spread source into an ambient response,
preventing such sources from being unexpectedly quiet.

5f7268c0cc Add a 5.1 preset that excludes the front-center speaker 
On some speaker setups, the front-center speaker is not designed for full-range
content and should be used exclusively for dialog. Consequently it should not
be used for positional sounds, only the dedicated dialog effect.

f313f9c117 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.
