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.

b3756709ad Fixed incorrect assumption about the number of bytes returned by the 
entropy coder. All testcases pass again.

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

6238bc0ece Moved the content of libentcode into libcelt to reduce dependencies, 
especially now that we have a custom version of that code anyway. Moved
the test code to tests/

94d4ea9305 Bit of cleaning up in the byte dumping part. Making use of any remaining bit(s) 
to do error detection in the decoder.

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

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).

to multiple MDCTs per frame. Not complete yet.

4a897680e3 Working on some stability issues (appears to be solved by making the pitch 
projection less aggressive). Also, fixed a 64-bit overflow in the stereo mode
and added a "band rotation" function.

11f01729e6 Some cleaning up, a few less warnings and the decoder no longer does an 
infinitete loop in Laplace decoding when the data is corrupted.
