28db7fce02 slow but accurate integer dct from IJG (should be ok with the LGPL as the old DCT is the fast integer DCT from IJG)

ce980a9576 new ratecontrol code
sadly there are no (unsigned) int left in AVCodecContext so this breaks shared libavcodec libs :(

0147f19856 beos/mov/adpcm patch by François Revol <revol at free dot fr>
* Some BeOS fixes:
- errno stuff
- nanosleep() replacement
- added a doc/README.beos

* mov reader still has problems with most videos (skips many chunks),
- It should now read .mov files with zlib-compressed moov headers (aka cmov)
- added SVQ1 support.
- removed mapping 'raw ' and 'yuv2' to h263, was my mistake.
- added IMA4 support. (tested)
- fixed frame rate (it reported 0 fps or something before)
- extended file probing ('wide' and 'free' atoms)
- improved .mov/.mp4 detection (or so I think)

* adpcm
* added zlib support, with header file and lib check

e0a3d744a0 - repeat_pict meaning changed, now it signals the extra delay for the
decoded frame.
- extra_delay = (repeat_pict / 2) * (1/fps)

dbc598bb79 - Commented out PIX_FMT_ANY by now. It seems that not all codecs are setting
the PIX_FMT_ so they get PIX_FMT_ANY instead of PIX_FMT_YUV420P which
obviuosly annoys ffmpeg.
