This particular bug fix for PyBuffer_ToContiguous() (which would automatically
fix memoryview.tobytes() in 2.7 and 3.2) is easy to backport.

For non-trivial buffers it's likely though that other problems
will show up in versions 2.7 and 3.2.


Backporting the *complete* rewrite would be relatively easy, too.
But that would change the layout of the MemoryView object etc.

Fixing all of #10181 without the drastic changes would be very time
consuming (if at all possible).
