I've uploaded a new patch that should address the remaining issues:

   o In the documentation _testbuffer has been replaced by
     m.cast() + the now multi-dimensional m.tolist().

   o I restored the state of the limited API. If we want
     to include Py_buffer again, I think this should be done
     in a separate patch.

   o Flags of the memoryview object are private.


Additionally, because NumPy allows non-aligned array accesses,
I changed the packing functions to use memcpy for multi-byte types.

On x86/amd64 gcc is smart enough to produce almost exactly the same
asm output as before, with a slowdown of 0-1%, depending on the
benchmark.

On other platforms the situation might be worse, but I don't have
access to real hardware where alignment actually matters.
