Once we bailed out we calculate the exact iteration in which it would have happened if needed.

Use log(sqrt(mb->bailout)) instead of log(mb->bailout) because mb->bailout represent
the bailout radius squared, and then simplify the two sqrt().
This is also slightly faster.

The interrupt callback has to be passed in during opening (setting it
after opening isn't enough), since a blocking open couldn't be
interrupted otherwise.

Options are passed down to procotols and also need to be available
during open() in most cases.

Not used anywhere yet, support for passing options from avio_open() will
follow.

There are a few more cases of chained demuxers, but they
only use custom IO which don't do any blocking IO and thus
don't need the callback.

Change all uses of these function to pass the relevant
callback on.

This is a better io interrupt callback function, which has an
opaque parameter, which is given to the interrupt callback.

This allows callers to precisely cancel IO for one single
AVFormatContext, without interrupt other ones in the same
process.

Note, it's not needed in AVIOContext, at the moment.
