4538729afe Move sine windows to a separate file 
These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.

26f548bb59 fft: remove inline wrappers for function pointers 
This removes the rather pointless wrappers (one not even inline)
for calling the fft_calc and related function pointers.

7ffe76e540 Merge libavcore into libavutil 
Done to keep ABI compatible. Otherwise this is just silly

737eb5976f Merge libavcore into libavutil 
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

7d485f165f Support for getting (i)MDCT output multiplied by a constant scaling factor. 
Scaling (i)MDCT output has no runtime overhead and can be used to improve
performance of audio codecs. All the changes are only needed in
'ff_mdct_init' function and slow down initialization a bit.

7a00bbad21 Implement avcodec_decode_video2(), _audio3() and _subtitle2() which takes an 
AVPacket argument rather than a const uint8_t *buf + int buf_size. This allows
passing of packet-specific flags from demuxer to decoder, such as the keyframe
flag, which appears necessary to playback corePNG P-frames.

"Google Summer of Code participation" on the mailinglist.

940d8f7614 As usual Real actually took something existing and rebranded it. 
Cook looks very much like G.722.1.

e7485bf378 Replace custom modified discrete cosine transform with ffmpeg's own. 
This does alter the decoded output, but not by much.
The new output is closer to that produced by Real's "official" decoder,
and the decoder runs slightly faster.

4ff5e6563e Don't output the first two frames, since they don't contain valid audio. 
This also eases comparison of decoded output with Real's binary decoder.
