Currently, "pip3 install --upgrade pip" unconditionally installs a
"pip" alias even for Python 3.  If a user has an existing Python 3.x
installed from a python.org macOS installer and then subsequently
manually updates to a new version of pip, there may now be a stray
"pip" alias in the Python 3.x framework bin directory which can cause
confusion if the user has both a Python 2.7 and 3.x installed;
if the Python 3.x fw bin directory appears early on $PATH, "pip"
might invoke the pip3 for the Python 3.x rather than the pip for
Python 2.7.  To try to mitigate this, the macOS installer script
for the ensurepip option will unconditionally remove "pip" from
the 3.x framework bin directory being updated / installed.  (The
ambiguity can be avoided by using "pythonx.y -m pip".)

Previously emitted cover files only when --missing option was used.

ast.c: fstring_fix_node_location() downcasts a pointer difference to
a C int. Replace int with Py_ssize_t to fix the compiler warning.

long_long() was used with three function types:
PyCFunction, getter and unaryfunction.

Use the _PyTime_t type and round away from zero (ROUND_UP,
_PyTime_ROUND_TIMEOUT) the sleep duration, when converting a Python
object to seconds and then to milliseconds. Raise an OverflowError in
case of overflow.

Previously the (int)double conversion rounded towards zero
(ROUND_DOWN).

In text and entry boxes, this affects selection by double-click,
movement left/right by control-left/right, and deletion left/right
by control-BACKSPACE/DEL.

They where silenced before.

METH_NOARGS functions need only a single argument but they are cast
into a PyCFunction, which takes two arguments.  This triggers an
invalid function cast warning in gcc8 due to the argument mismatch.
Fix this by adding a dummy unused argument.

The wording here seems wrong, as per https://bugs.python.org/msg315792

Cast pointer difference from ssize_t to int: a frame is very unlikely
larger than 2 GB.

Fix test_embed.test_pre_initialization_sys_options() when building with --enable-shared

Previously, the predicate parameter was mentioned, but what it was to be
called with was not documented and required either trial-and-error or
looking into the source to find that it is called with the `value`, or
second item, of the full members list. This change addresses what the
predicate will receive, as well as does some light formatting to make
this clear.

Added tests to ensure that all defined opcodes are supported.

Patch by Neeraj Badlani.

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-33251: ConfigParser.items no longer returns items present in vars.

Documentation for `ConfigParser.items()` states:
'Items present in vars no longer appear in the result.'

This fix aligns behaviour to that specified in the documentation.
