Generate the bsinc tables using constexpr methods
...
All the methods used should be compliant with C++14 constexpr rules. However,
the number of scales and phases cause GenerateBSincCoeffs to reach the allowed
step limit, preventing full compile-time generation. It's not a terribly big
deal, it'll generate them very quickly when loading, but it does prevent using
shared read-only memory pages.

Dynamically allocate voice channel data
...
Rather than allocating for a full 8 channels for each voice, when the vast
majority will only need 1 or 2. The voice channel data is relatively big since
it needs to hold HRTF coefficients and history, and this will allow increasing
the maximum number of buffer channels without an obscene memory increase.

Use an array of ALvoice pointers for the active voices
...
This allows growing the array atomically with the mixer since the ALvoice
objects themselves don't move, and a new larger array of them can be swapped in
without blocking the mixer.

Currently only first-order B-Format is possible for a buffer/source, but this
will begin to allow for higher orders with an appropriate extension.
