5b50f4bf81 Decays corresponding to the psychoacoustic spreading function are now 
pre-computed (instead of computing tons of pow() uselessly all the time)

b7ed44ba0a minor tweak to pitch weighting function, disabled some code that doesn't 
do anything yet.

7351e286c8 Everything converted to use kiss-fft. Got rid of smallft and fftwrap. 
Code much leaner now.

6211c90def Split the radix functions into forward and backward versions, removed the 
"inverse" flag from the state so it can be shared between the forward and
inverse transforms.

711ad251df Changed ordering of real FFT freq data to something more aligned (it's not 
used anywhere yet).

012407760c Re-enabled intra-frame prediction, which seems to have exposed a few issues 
with the entropy coder.

2fecbdf084 Fixed the default int32 type which was wrong on amd64 (and added testcase). 
Also, added an Ogg encoder (doesn't work quite yet).

4c6bc884c8 "make check" now actually tried to encode and decode to see if things work 
(need to have test files installed otherwise it'll just pass by default)

the test code to tests/

to do error detection in the decoder.

7e3293f713 Fix the bug that was causing the last byte of the stream to be returned incorrectly, as well as undo jm's reversion, which can cause ec_dec_tell() to operate incorrectly at the end of the stream. 
A few other minor updates are included as well.

pkg-config file)

388f1d6cc8 Tweaks for slightly improving the handling of the last byte (still not 
perfect)

e5ec0f8da3 Reverted some of Timothy's changes to the range decoding that were causing decode random decode problems at the end of the stream (but only once in a while).

a76a0b23eb Further simplified the API by passing the rate directly to the 
encode function. Also, trying to properly flush the bit packer
(still some problems left).

649d5cc23b Update ec_dec_bits64() to correspond to the new ec_enc_bits64(). Not sure why this wasn't committed before.
