Issue #14181 : Preserve backwards compatibility for getbufferprocs that a) do

- 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.

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.
