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

8758f7e43c * for this moment bswap.h included ahead of HAVE_AV_CONFIG_H check
as its functionality is used even in those parts which are being
  compiled without this flag
  - generaly this would require more complicated cleanup patch
  - for now leaving for the main author

05f361f0c7 (commited by michael / arpi was crazy enough to give me his password)
fixed a bug in get_vlc() when using the ALT_BITSTREAM_READER (rv10 & mpeg12 decoders where not working)
some optimizations
 replaced a if() with a >>
 changed get_bits1() a bit so it hopefully is faster on p4
