As per issue2629, most 23.976fps matroska H.264 files are incorrectly
detected as 24fps, as the matroska timestamps usually have only
millisecond precision.
Fix that by doubling the amount of timestamps inspected for frame rate
for streams that have coarse time base. This also fixes 29.970 detection
in matroska.

When symbol versioning is enabled, moving symbols from one library to
another breaks binary compatibility. This adds wrappers with the old
version tag for the av_*packet functions recently moved to lavc.

this patch restores binary compatibility for the av_*_packet symbols that have
been moved from libavformat to libavcodec. This patch works for gnu toolchains
only; support for ARM RCVT will be handed in for a later point release as soon
as the patch is ready and approved by the ARM maintainer(s).

set to probe_max_size in the last iteration.
Also make the function return an error if we get to the max probe
length and still cannot figure out what the format is.

AVERROR_NOFMT if the format is unknown / cannot be recognized.
It is returned AVERROR_INVALIDDATA, in the sense that the data is
invalid within what the specific libav* binary supports.
That was the last remaining use of AVERROR_NOFMT, which is going to be
dropped at the next libavutil major bump.

If the format probe hits end of file, do not add the error code
to the buffer position. This is obviously wrong, and with a
small input file would cause a negative buffer overflow.
Fixes issue 1818.

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.
