asf_read_seek() inside the asf demuxer already does the
right thing, it tries the index and if that fails it uses
binary search. If binary search is called from outside of asfdec.c
it will fail because the asf code cannot clean up after itself.
Therefore introduce AVFMT_NOBINSEARCH that prevents the seek
code to fallback to binary search and AVFMT_NOGENSEARCH that
prevents the seek code to fallback to generic search.
In the main loop, stream_number is incremented after checking the stream type,
so the search usually will not find the wanted stream.
This patch eliminates the useless stream_number variable and introduces a new
one, called real_stream_index to store the real stream index of the current
stream, no matter if we are looping through all the streams or only the streams
of a program.

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

If the format probe hits end of file, do not add the error code

Originally committed as revision 22571 to svn://svn.ffmpeg.org/ffmpeg/trunk
av_probe_input_buffer() so that it can be reused. Here are a few
differences to the original way things were probed:
- maximum probe buffer size can be specified as a parameter.
- offset within the stream to probe from can be specified as a parameter.
- instead of seeking back to the start each time a probe fails, stream
data is appended to the reallocated buffer. This lowers the amount
of data read from the stream (there is no repetition) and results in
fewer closed and reopened streams (when seeking fails).
New attempt after r22296, which was revert in r22315 due to a FATE
failure.

not reliable when backwards compatible signaling is used.

av_probe_input_buffer() so that it can be reused. Here are a few
differences to the original way things were probed:
- maximum probe buffer size can be specified as a parameter.
- offset within the stream to probe from can be specified as a parameter.
- instead of seeking back to the start each time a probe fails, stream
data is appended to the reallocated buffer. This lowers the amount
of data read from the stream (there is no repetition) and results in
fewer closed and reopened streams (when seeking fails).

and clone its code to ffserver_guess_format() in ffserver.c.
guess_stream_format() is hackish since it relies on some undocumented
properties of the name of the muxers (wich is currently only relevant
for the ASF muxer), and has no use outside ffserver.c.

These values should not matter at all in principle because they
do not correspond to the time of display of any frame but it seems
ffmpeg becomes confused by them if they are far off and its not
strictly correct to set them to guessed values.

This changes add_to_pktbuf() to maintain a pointer to the last entry
in the list, avoiding a linear walk-through on each call. Before this
change, add_to_pktbuf() could take a significant amount of time (10%
of total decoding time), even with input files of several minutes.
After the change, the time spent in this function is barely measurable
with oprofile.
