6e6cc830c4 Issue #9757: memoryview objects get a release() method to release the 
underlying buffer (previously this was only done when deallocating the
memoryview), and gain support for the context management protocol.

c3b39245a7 Issue #4580: slicing of memoryviews when itemsize != 1 is wrong. 
Also fix len() to return number of items rather than length in bytes.

I'm sorry it was not possible for me to work on this without reindenting
a bit some stuff around. The indentation in memoryobject.c is a mess,
I'll open a separate bug for it.

   Added checks for integer overflows, contributed by Google. Some are
   only available if asserts are left in the code, in cases where they
   can't be triggered from Python code.

b35f128711 At least one of the buildbots was complaining about newview being used 
without being initialized.  Also make the code conform to the comment and
return the new object.  This code needs a test!

666bb419cb SF #1777057, fix memoryview('test') so it works in debug mode too. 
Also return a boolean for the readonly flag.

Other cleanup: make sure to set an exception when returning NULL and
reformat the getsets to be shorter by putting them all on one line.

faa54a3929 Code review of the new buffer protocol. Mostly add questions that should 
be answered with the comments removed.

There are many places that require checks when doing arithmetic for memory
sizes when allocating memory.  Otherwise, overflow is possible with
a subsequent crash.

Fix SF #1777057 which was a result of not initializing the new BufferError
properly.  Had to update the test for exceptions for BufferError too.
