Currently the file overwrite check does not work for paths that
contain a colon.

Use avio_find_protocol to always execute the existence check if
the file protocol is going to be used.

Fix remaining part of ticket #3249.

I found the optimisation of 2 samples per iteration obscured the
underlying algorithm.  I had to write it out on paper and translate into
a mathematical sum to see that the two samples are unconnected.  I hope
that if anyone else is struggling to understand the code that this will
be useful.
