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.

On OS X 10.7 and 10.6 with Xcode 4.2, building Distutils-based packages with
C extension modules may fail because Apple has removed gcc-4.2, the version
used to build python.org 64-bit/32-bit Pythons.  If the user does not
explicitly override the default C compiler by setting the CC environment
variable, Distutils will now attempt to compile extension modules with clang
if gcc-4.2 is required but not found. Also as a convenience, if the user
does explicitly set CC, substitute its value as the default compiler in the
Distutils LDSHARED configuration variable for OS X. (Note, the python.org
32-bit-only Pythons use gcc-4.0 and the 10.4u SDK, neither of which are
available in Xcode 4.  This change does not attempt to override settings to
support their use with Xcode 4.)

unreliable since tests or user programs could modify the interpreter
environment after Distutils set it.  Instead, have Distutils set the
deployment target only in the environment of each build subprocess.  It is
still possible to globally override the default by setting
MACOSX_DEPLOYMENT_TARGET before launching the interpreter; its value must be
greater or equal to the default value, the value with which the interpreter
was built.  Also, implement the same handling in packaging.
