Stefan Krah 1649c1b33a Issue #14181: Preserve backwards compatibility for getbufferprocs that a) do
not adhere to the new documentation and b) manage to clobber view->obj before
returning failure.

Stefan Krah 4e99a315b7 Issue #14181: Allow memoryview construction from an object that uses the
getbuffer redirection scheme.

Stefan Krah 9a2d99e28a - Issue #10181: New memoryview implementation fixes multiple ownership
and lifetime issues of dynamically allocated Py_buffer members (#9990)
  as well as crashes (#8305, #7433). Many new features have been added
  (See whatsnew/3.3), and the documentation has been updated extensively.
  The ndarray test object from _testbuffer.c implements all aspects of
  PEP-3118, so further development towards the complete implementation
  of the PEP can proceed in a test-driven manner.

  Thanks to Nick Coghlan, Antoine Pitrou and Pauli Virtanen for review
  and many ideas.

- Issue #12834: Fix incorrect results of memoryview.tobytes() for
  non-contiguous arrays.

- Issue #5231: Introduce memoryview.cast() method that allows changing
  format and shape without making a copy of the underlying memory.

Antoine Pitrou 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.

Neal Norwitz 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.

Neal Norwitz 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.
