d6a4c0b111 * some modifications to allow gcc to compile same code for -fPIC 
- introduced MOVQ_WONE, MOVQ_WTWO
* unrolled put_pixels_clamped_mmx
* added .baling where the jump address would be compiled on odd address
* added some testing code to disable all these routines (for time measurement)

80e103d04c PATCH by Rik Snel <rsnel@cube.dyndns.org> 
this patch enhances the jpeg header writer. It can be asked to omit
quantisation and huffman tables and it can write different horizontal and
vertical sampling factors. (the last thing is useless for libavcodec
itself (because libavcodec only handles YUV420P at ecoder level), but the
values are initialized so that operation of libavcodec is not impaired)

fixed a bug in get_vlc() when using the ALT_BITSTREAM_READER (rv10 & mpeg12 decoders where not working)

 replaced a if() with a >>
 changed get_bits1() a bit so it hopefully is faster on p4
