Victor's changes to our encoder give reasonable performance on arm (<10% 
of cpu on an arm9 400mhz I think). It uses 64-bit integer math and we 
expect there is room for even more optimization using a lossier 32-bit 
version (the 32-bit stuff is stubbed out but disabled for now since it's 
incomplete)

In addition to switching to integer ops, Victor unrolled loops and 
reworked some of the tables so less stuff has to be computed at runtime.

Real-world testing and dev work remain, so if someone has one of these 
Nokias already, please pipe up so we can give the encoder a workout.
