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

e1707f52d5 BeOS patches by "shatty" <shatty at myrealbox.com> 
1. errno's are negative on beos, so negating them gives positive values.
2. the -shared flag is -nostart on beos.
3. building the shared lib on beos requires -fomit-frame-pointer
4. beos doesn't have oss support

8155233413 fixed layer1/2 overflow if very loud sound - fixed broken free format decoding to pass all mpeg audio standard decoding tests (please avoid patching the parser without having all test streams available - contact me if necessary)

fca0f0e59f * removed MANGLE from macros for setting constants 
* using MOVQ_WONE/MOVQ_BFE as two instruction instead of static memory value access
  as its always faster
* PAVGB_MMX macro is using now mm6 -> mm7 is unmodified
* replaced original pixels_xy2_mmx with new faster and equal implementation
* replaced usage of mm7 for other then ZERO contstant in _rnd & _avg file with mm6

ff9657069a * using unrolled loops seems to help to MMX Celerons 
* calculating average in parallel to use two MMX units
* disabled xy2 put code - it's producing rouding errors

6aa6ea8e11 * reenabled original xy2 put routine - rounding error is really bad with 
the new code
* added PAVGP macros for parallel processing to safe few more cycles on
  celerons
