29fba79cd5 Avoid 5.1Rear as its own channel configuration 
It messes with 5.1 sources using direct channels, and the surround channels are
supposed to map to the side labels. Individual backends can deal with the
channel order/label differences, as they already do to a degree.

d38c8419c7 Update the 5.1+center decoder and use it by default 
The itu5.1-nocenter preset is the same as the previous default, so it can still
be used for people that prefer it. But this new one purportedly has better
panning and positioning responses in listening tests, which initial impressions
concur with.

5b2489c3e8 Convert AmbDecConf to DecoderConfig for loading 
This keeps AmbDecConf uses confined to multi-channel panning initialization,
and avoids spreading conversions and maps all over.

b54bb388a3 Create a base the ALCdevice and ALCcontext structs 
A base that contains the API-agnostic data, with ALCdevice and ALCcontext being
for AL-specific data.

7387148006 Use the root mean square for the HRTF B-Format HF scale 
For the second-order decoder. Since the delays are adjusted to avoid most high
frequency phase cancelation, the energy-based scaling with the number of
channels used creates a significant HF increase. Using the RMS-based scaling
seems to create a more level response, though it's not perfect either. More
testing and measurements may be needed.

8a86ec8ac5 Add a crossover frequency field for the device 
Used when upsampling low-order ambisonic signals to higher order. Rather than a
hardcoded 400hz, it ensures a consistent crossover point when an ambdec
configuration is used. It can also allow for an alsoft config option.

52d58a4023 Store the wet buffers in the context 
This is rather ugly, but we need the wet buffers to remain allocated after its
effect slot is deleted, because a voice can still use it for its final fade-out
mix.
