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.

Various tests fail when run under coverage. A primary culprit is refcount tests
which fail as the counts are thrown off by the coverage code. A new decorator
-- test.support.refcount_test -- is used to decorate tests which test refcounts
and to skip them when running under coverage. Other tests simply fail because
of changes in the system (e.g., __local__ suddenly appearing).
Thanks to Kristian Vlaardingerbroek for helping to diagnose the test failures.

recursion depth gets triggered.
Closes issue #10985. Code review by Georg Brandl.
* Expose the build flags to Python as sys.abiflags
* Shared library libpythonX.Y<abiflags>.so
* python-config --abiflags
* Make two distutils tests that failed with --enable-shared (even before this
patch) succeed.
* Fix a few small style issues.
environment variable to set the filesystem encoding at Python startup.
sys.setfilesystemencoding() creates inconsistencies because it is unable to
reencode all filenames in all objects.
_Py_char2wchar() (mbctowcs) decodes b'\xff' to '\xff' on FreeBSD, Solaris and
Mac OS X, even if the locale is C (and the locale encoding is ASCII). Patch
test_undecodable_code() to support this output and document the two different
kinds of outputs.
The test is still failing on "x86 FreeBSD 7.2 3.x" and "sparc solaris10 gcc
3.x" buildbots. It looks like the locale encoding is able to decode b'\xff'. I
suppose that it is an encoding like 'iso-8859-1'.
Use C locale to set, I hope, the locale encoding to 'ascii'. Display also the
encoding so if the test fails, at least I will learn the locale encoding
choosen for the C locale.
There are buildbot failures on "x86 FreeBSD 3.x" and "sparc solaris10 gcc 3.x".
I suppose that _Py_char2wchar() doesn't fail even if the locale encoding is
unable to decode the byte string, because _Py_char2wchar() has a special mode
for platform without mbrtowc() (ISO C99) function.
Let's check my theory by avoid error on the Python print() instruction.
