Call ALfilterState_processC directly
...
It's the only implementation currently, so there's no point to having it stored
as a function pointer in the filter struct. Even if there were SIMD versions,
it'd be a global selection, not per-instance.

Provide (mostly) lockless updates for effect slots
...
Similar to the listener, separate containers are provided atomically for the
mixer thread to apply updates without needing to block, and a free-list is used
to reuse container objects.
A couple things to note. First, the lock is still used when the effect state's
deviceUpdate method is called to prevent asynchronous calls to reset the device
from interfering. This can be fixed by using the list lock in ALc.c instead.
Secondly, old effect states aren't immediately deleted when the effect type
changes (the actual type, not just its properties). This is because the mixer
thread is intended to be real-time safe, and so can't be freeing anything. They
are cleared away when updates reuse the container they were kept in, and they
don't incur any extra processing cost, but there may be cases where the memory
is kept around until the effect slot is deleted.

More directly map coefficients for ambisonic mixing buffers
...
Instead of looping over all the coefficients for each channel with multiplies,
when we know only one will have a non-0 factor for ambisonic mixing buffers,
just index the one with a non-0 factor.

Although it is more correct for preserving the apparent volume, the ambisonics-

comparison.
