optimization & bugfix extracted from the 4k line diff between ffmpeg 0.4.7 and http://www.alicestreet.com/ffh263.html
the other parts of the diff where
1. spelling fixes (rejected as only a small part of it could be applied automatically)
2. cosmetics (reindention, function reordering, var renaming, ...) with bugs (rejected)
3. rtp related stuff (rejetced as it breaks several codecs)
4. some changes to the intra/inter decission & scene change detection (quality tests needed first)

  adaptively change middle position selection algo for seeking, this avoids some ugly worstcases of the interpolated variant
  avoid backward search for mpeg where possible, its 17 times slower then forward according to my benchmark

Originally committed as revision 2710 to svn://svn.ffmpeg.org/ffmpeg/trunk

store searched distance in index, so we dont waste time searching for keyframes where we already searched
asf seek fixes & use keyframe pos/timestamp cache

replic_size==0 fix, needed so that G.726 asf file, so ffmpeg can at least decode the video without segfaulting

Originally committed as revision 2706 to svn://svn.ffmpeg.org/ffmpeg/trunk

dont let the demuxer thread die before the video has actually been played as seeking would become impossible shortly before EOF

  memleaks
  infinite loops
  uninitalized variables
with some luck u can seek now a few times before it dies

Originally committed as revision 2702 to svn://svn.ffmpeg.org/ffmpeg/trunk

multiple stream seeking (yes i know seeking is still broken)
related cleanup

bug was introduced in version 1.75 (2003-12-30)
this may have lead to a small drop in quality of the 4mv mode, but should have only affected the mbd=0 case

Originally committed as revision 2698 to svn://svn.ffmpeg.org/ffmpeg/trunk

move (av_)find_stream_index() to utils.c as its usefull outside mpeg.c
assert checking enabled, to find bugs quicker, should obviously be disabled later
(av_)add_index_entry() inserts new entries so that the list stays ordered and updates entries if already in it
(av_)index_search_timestamp() cleanup (kill ugly goto) and shorter
