GetBitContext.size is allways multiplied by 8 -> use size_in_bits to avoid useless *8 in a few inner loops

FOURCC removed, using ff_get_fourcc instead (should be big-endian safe), workarounded a restart interval bug (Spectralfan.mov) (rst support should be rewritten and moved from decode_sos)

alternative bitstream writer (disabled by default, uncomment #define ALT_BISTREAM_WRITER in common.h if u want to try it)

Originally committed as revision 295 to svn://svn.ffmpeg.org/ffmpeg/trunk

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)
