This allows collecting statistics on probing scores and the amount of data
probing needed for various files and formats.
For example it can be used to find out which formats tend to need more
data for probing or which files are probed with less certain/lower scores

The intent of the original check was to increase has_b_frames when
it was incorrectly set to 0. Later codecs allowed larger values

previously only codec_ids could be forced, which did not allow
forcing a specific implementation like libopenjpeg vs jpeg2000.

lavf: Make probe_codec return an error code
Conflicts:
libavformat/utils.c
A failure to reallocate should not free the array as it is used
to probe the codec. And failure to reallocate if the following
probe succeeds isnt a fatal error for probe_codec(). Thus this
is only partially merged to ensure probing still is attempted
with the data available.

The caller does not expect this, and in case of adding new streams would then
not even be able to deallocate them anymore.
This reverts a hunk from "avformat: Use av_reallocp_array() where suitable"

The check added in df33a58e53 does not work
at all, rather it broke the summing of bitrates completely.
The comparission was wrong way around.
This commit replaces it by a simpler and hopefully clearer check

This causes a race condition with VLC. Its plausible that other
applications also would have races with it and its just fixing a memleak when
the user application forgets to free the codec. It causes more
problems than it solves in its current form, thus the revert.
Better solutions are welcome

The sample from ticket #2691 currently does not trigger "Consider increasing
the value for analzeduration and probesize" because the audio streams are
only added after calling estimate_timings(). Attached patch moves the message

This is part of normal operation with some formats. A warning should
indicate that something is wrong, and the documentation for AV_LOG_WARNING
says: "Something somehow does not look correct."
Since this message is most likely useful for debugging only, raise the
log level accordingly.

If the demuxer implements read_seek2() and not read_seek(),
call avformat_seek_file() from av_seek_frame().
Allow to properly seek in formats that only implement the
new API from applications that use the old one.
Tested with mplayer and a concat script.
