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.

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.

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.

type of tp_compare in a separate commit, for ease of reversion

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.
