Combine the reverb effects
...
Updating and processing still differs depending on whether standard or EAX
reverb is used or not. The only functional difference should be that the
allocated buffer (and subsequent offsets) take into account the modulation
and echo times.

Scale reverb output based on the number of channels

A scale of sqrt(2/numchannels) is used so the perceived volume matches as if it
was stereo output, which seems to match other implementations.

Be context-agnostic in the effect Create functions
...
This allows the effect Update functions to handle the playback frequency being
changed. By default the effects assume a maximum frequency of 192khz, however,
it can go higher at the cost of the sample buffers being cleared and the risk
of an abort() if reallocation fails
