de8c5b1824 Combine the chorus and flanger processing functions 
Given that they're nearly identical, it should be relatively simple to use the
same effect state to process either of them, similar to the reverbs. The big
differences seem to be the delay range (much shorter with flanger) and the
defaults.

56e9cb69d3 Ensure the chorus delay and depth leave enough padding for resampling 
Also use cubic resampling for the modulated tap. Applies to flanger too.

dabb99de8d Don't offset the chorus/flanger delay and LFO 
The delay being added to the scaled LFO will ensure a proper positive result
regardless.

661bd054aa Use a single delay line for chorus feedback on a fixed tap 
The outputs themselves use a variale-delay tap, but using a separate fixed-
delay tap on the feedback helps improve the perceived "wobble" with sustained
notes. This also applies to the flanger effect.

d281b25723 Use a separate LFO offset in the chorus effect 
Given that the LFO range is not a power-of-two, it won't correctly wrap on
overflow.

653f0a1405 Fix handling chorus and flanger LFO displacement offset 
The phase offset is modulo-wrapped rather than masked, so it's best to avoid
negative offsets.

2b14c1d623 Properly handle the chorus and flanger LFOs 
The effects' specified delay is the average delay time, meaning the delay
offset should move between -n and +n relative to the delay, where n <= delay.

ef0d4f8210 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.

a6c70992b0 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.
