sporadic crashes in multi-thread programs when several long deallocator
chains ran concurrently and involved subclasses of built-in container
types.
Because of this change, a couple extension modules compiled for 3.2.4
(those which use the trashcan mechanism, despite it being undocumented)
will not be loadable by 3.2.3 and earlier. However, extension modules
compiled for 3.2.3 and earlier will be loadable by 3.2.4.

The environment variable PYTHONHASHSEED and the new command line flag -R control this
behavior.

* PyUnicode_EncodeFSDefault(), PyUnicode_DecodeFSDefaultAndSize() and
PyUnicode_DecodeFSDefault() use the locale encoding instead of UTF-8 if
Py_FileSystemDefaultEncoding is NULL
* redecode_filenames() functions and _Py_code_object_list (issue #9630)
are no more needed: remove them
Redecode the filenames of:
- all modules: __file__ and __path__ attributes
- all code objects: co_filename attribute
- sys.path
- sys.meta_path
- sys.executable
- sys.path_importer_cache (keys)
Keep weak references to all code objects until initfsencoding() is called, to
be able to redecode co_filename attribute of all code objects.
(instances of int, float, complex, decimal.Decimal and
fractions.Fraction) that makes it easy to maintain the invariant that
hash(x) == hash(y) whenever x and y have equal value.

handle_system_exit() flushs files to warranty the output order
PyObject_Print() writes into the C object stderr, whereas PySys_WriteStderr()
writes into the Python object sys.stderr. Each object has its own buffer, so
call sys.stderr.flush() and fflush(stderr).

Use a more robust infinity check in _Py_HashDouble.
This fixes a test_decimal failure on FreeBSD 8.0. (modf apparently
doesn't follow C99 Annex F on FreeBSD.)

Issue #789290: make sure that hash(2**63) == hash(2.**63) on 64-bit
platforms. The previous code was fragile, depending on the twin
accidents that:
(1) in C, casting the double value 2.**63 to long returns the integer
value -2**63, and
(2) in Python, hash(-2**63) == hash(2**63).
There's already a test for this in test_hash.
