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.

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.

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.

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.
