Use types.GenericAlias in inspect.formatannotation to correctly add
type arguments of builtin types to the string representation of
Signatures.

Objects that support garbage collection ("container" objects) should
call PyObject_GC_UnTrack() from their destructors before clearing any
fields which may point to other "container" objects.
(original patch by eryksun)
Correctly hand various failure modes when resizing an mmap on Windows:
* Resizing a pagefile-backed mmap now creates a new mmap and copies data
* Attempting to resize when another mapping is held on the same file raises an OSError
* Attempting to resize a nametagged mmap raises an OSError if another mapping is held with the same nametag
* record which modules are build as shared extensions
* put object files in same directory as source files
* remove dependency on deleted _math.c

Adds _ctypes, _decimal, _multiprocessing, _posixshmem, _scproxy, _sqlite3,
and _uuid.
Use Makefile variables to build OpenSSL and TCL/TK modules.
Drop ``-lm`` from math lines. Extensions are always linked against libm.

``setup.py`` and ``makesetup`` now track build dependencies on all Python
header files and module specific header files.

The :mod:`math` and :mod:`cmath` implementation now require a C99 compatible
``libm`` and no longer ship with workarounds for missing acosh, asinh,
expm1, and log1p functions.
The changeset also removes ``_math.c`` and moves the last remaining
workaround into ``_math.h``. This simplifies static builds with
``Modules/Setup`` and resolves symbol conflicts.

Keep track of whether unsafe_tuple_compare() calls are resolved by the very
first tuple elements, and adjust strategy accordingly. This can significantly
cut the number of calls made to the full-blown PyObject_RichCompareBool(),
and especially when duplicates are rare.

The recently added PyConfig.stdlib_dir was being set with ".." entries. When __file__ was added for from modules this caused a problem on out-of-tree builds. This PR fixes that by normalizing "stdlib_dir" when it is calculated in getpath.c.

* ``HAVE_EXPAT_CONFIG_H`` is not used by our code and not used by
system-wide expat header files
* ``USE_PYEXPAT_CAPI`` is no longer used by our code
* ``XML_POOR_ENTROPY`` should be defined in expat_config.h

setup.py no longer defines Py_BUILD_CORE_MODULE. Instead every
module defines the macro before #include "Python.h" unless
Py_BUILD_CORE_BUILTIN is already defined.
Py_BUILD_CORE_BUILTIN is defined for every module that is built by
Modules/Setup.
The PR also simplifies Modules/Setup. Makefile and makesetup
already define Py_BUILD_CORE_BUILTIN and include Modules/internal
for us.

This is a cross-platform check that the symbols are actually
exported in the ABI, not e.g. hidden in a macro.
Caveat: PyModule_Create2 & PyModule_FromDefAndSpec2 are skipped.
These aren't exported on some of our buildbots. This is a bug
(bpo-44133). This test now makes sure all the others don't regress.
MAP_BOT_LENGTH was incorrectly used to compute MAP_TOP_MASK instead of
MAP_TOP_LENGTH. On 64-bit machines, the error causes the tree to hold
46-bits of virtual addresses, rather than the intended 48-bits.
Freelists for object structs can now be disabled. A new ``configure``
option ``--without-freelists`` can be used to disable all freelists
except empty tuple singleton. Internal Py*_MAXFREELIST macros can now
be defined as 0 without causing compiler warnings and segfaults.
