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.

allowed as the API is still considered non-stable.

"random".

This is useful for testing the slice support, but it is not supposed
to be used for other purposes and this interface may change in the
future, thus it is not documented.

The randomization algorithm adopted is the standard Numerical Recipes
