2pass ratecontrol
fixed hq with 2pass
inceased build num (a few more vars for the rc stuff)
hopefully no new bugs

do MC on encoding only once if possible
bugs? ;)

sure it works ok. Also it's slow, so use it only when you _really_ need to
measure quality.
- Fix libavcodec Makefile to enable profiling.

DCT/Quantization is done after we have calculated all the MV of the picture.
- This is the preamble for a better bit rate control.

- RTP callback system implemented for H.263/H.263+.
- Bug fix on DC coefficients of H.263.
- H.263 decoder now returns PTS on picture number.

this includes the range for quantized dct coefficients in dct_quantize() (-1023...1023)

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)

mmx & mmx2 quantizer
c dct permutation bugfix
dont copy input on intra only encodings if it can be avoided
dont draw edges on intra only stuff
