bpo-33128 Fix duplicated call to importlib._install_external_importers (GH-6273)
External importers were being added in both phases of the import
system initialisation.
They're only supposed to be added in the second phase, after the
import machinery has been appropriately configured.

bpo-33329: Fix multiprocessing regression on newer glibcs (GH-6575) (GH-6579)
Starting with glibc 2.27.9000-xxx, sigaddset() can return EINVAL for some
reserved signal numbers between 1 and NSIG. The `range(1, NSIG)` idiom
is commonly used to select all signals for blocking with `pthread_sigmask`.
So we ignore the sigaddset() return value until we expose sigfillset()
to provide a better idiom.

bpo-33312: Fix clang ubsan out of bounds warnings in dict. (GH-6537) (GH-6543)
Fix clang ubsan (undefined behavior sanitizer) warnings in dictobject.c by
adjusting how the internal struct _dictkeysobject shared keys structure is
declared.
This remains ABI compatible. We get rid of the union at the end of the
struct being used for conveinence to avoid typecasting in favor of char[]
variable length array at the end of a struct. This is known to clang to be
used for variable sized objects and will not cause an undefined behavior
problem. Similarly, char arrays do not have strict aliasing undefined
behavior when cast.
PEP-007 does not currently list variable length arrays (VLAs) as allowed
in our subset of C99. If this turns out to be a problem, the fix to this is
to change the char `dk_indices[]` into `dk_indices[1]` and restore the
three size computation subtractions this change removes:
`- Py_MEMBER_SIZE(PyDictKeysObject, dk_indices)`

bpo-33185: Fix regression in pydoc CLI sys.path handling (GH-6419)
The pydoc CLI assumed -m pydoc would add the empty string
to sys.path, and hence got confused when it switched to
adding the full initial working directory instead.
This refactors the pydoc CLI path manipulation to be
more testable, and ensures it won't accidentally
remove the standard library directory containing
pydoc itself from sys.path.

bpo-32726: macOS 10.6+ installer now builds Tcl/TK 8.6 (GH-6308)
Build and link with private copy of Tcl/Tk 8.6 for the macOS 10.6+
installer. The 10.9+ installer variant already does this. This means that
the Python 3.7 provided by the python.org macOS installers no longer need or
use any external versions of Tcl/Tk, either system-provided or user-
installed, such as ActiveTcl.
bpo-32726: Do not force IDLE.app to launch in 32-bit mode. (GH-6280)
Forcing the macOS IDLE.app gui process to launch in 32-mode was
a necessary hack for old versions of Tk (Aqua Carbon as in Tk 8.4
and early versions of 8.5); it is not needed for current versions
of Tk. Since 32-bit launching will no longer be supported on
future releases of macOS, allow IDLE.app to launch in 64-bit mode.

bpo-32873: Treat type variables and special typing forms as immutable by copy and pickle (GH-6216)
This also fixes python/typingGH-512
This also fixes python/typingGH-511
As was discussed in both issues, some typing forms deserve to be treated
as immutable by copy and pickle modules, so that:
* copy(X) is X
* deepcopy(X) is X
* loads(dumps(X)) is X GH- pickled by reference
This PR adds such behaviour to:
* Type variables
* Special forms like Union, Any, ClassVar
* Unsubscripted generic aliases to containers like List, Mapping, Iterable
This not only resolves inconsistencies mentioned in the issues, but also
improves backwards compatibility with previous versions of Python
(including 3.6).
Note that this requires some dances with __module__ for type variables
(similar to NamedTuple) because the class TypeVar itself is define in typing,
while type variables should get module where they were defined.
