On Linux, skip tests using multiprocessing if the current user cannot
create a file in /dev/shm/ directory. Add the
skip_if_broken_multiprocessing_synchronize() function to the
test.support module.

Fix test_copyreg when numpy is installed: test.pickletester now

filters installed by numpy.
Add the save_restore_warnings_filters() function to the

ensurepip optionally installs or upgrades 'pip' and 'setuptools' using
the version of those modules bundled with Python. The internal PIP
installation routine by default temporarily uses its cache, if it
exists. This is undesirable as Python builds and installations may be
independent of the user running the build, whilst PIP cache location
is dependent on the user's environment and outside of the build
environment.
At the same time, there's no value in using the cache while installing
bundled modules.
This change disables PIP caching when used in ensurepip.

In Python 3.7 the behavior of parse_multipart changed requiring CONTENT-LENGTH
header, this fix remove this header as required and fix FieldStorage
read_lines_to_outerboundary, by not using limit when it's negative,
since by default it's -1 if not content-length and keeps substracting what
was read from the file object.
Also added a test case for this problem.

The doccumentation at https://docs.python.org/3.10/library/weakref.html cautions that the `WeakKeyDictionary` and `WeakValueDictionary` are susceptible to the problem of dictionary mutation during iteration.
These notes present the user with a problem that has no easy solution.
I dug into the implementation and found that fortunately, Antoine Pitrou already addressed this challenge (10 years ago!) by introducing an `_IterationGuard` context manager to the implementation, which delays mutation while an iteration is in progress.
I asked for confirmation and @pitrou agreed that these notes could be removed:

test_repl.test_close_stdin() now calls
support.suppress_msvcrt_asserts() to fix the test on Windows.
* Move suppress_msvcrt_asserts() from test.libregrtest.setup to
test.support. Make its verbose parameter optional: verbose=False by
default.
* SuppressCrashReport now uses SetErrorMode() of the msvcrt module,
rather than using ctypes.
* Remove also an unused variable (deadline) in wait_process().

* bpo-40826: Fix GIL usage in PyOS_Readline() (GH-20579)
Fix GIL usage in PyOS_Readline(): lock the GIL to set an exception.
Pass tstate to my_fgets() and _PyOS_WindowsConsoleReadline(). Cleanup
these functions.
(cherry picked from commit c353764fd5)
* bpo-40826: Add _PyOS_InterruptOccurred(tstate) function (GH-20599)
my_fgets() now calls _PyOS_InterruptOccurred(tstate) to check for
pending signals, rather calling PyOS_InterruptOccurred().
my_fgets() is called with the GIL released, whereas
PyOS_InterruptOccurred() must be called with the GIL held.
test_repl: use text=True and avoid SuppressCrashReport in
test_multiline_string_parsing().
Fix my_fgets() on Windows: fgets(fp) does crash if fileno(fp) is closed.

Would be nice to backport to python 3.7+. I don't think it's worth the hassle to backport this all the way down to 3.10. But I'll let the maintainers decide.
This is hard to test because the test setup already includes this [environment variable](https://github.com/python/cpython/blob/master/Lib/test/pythoninfo.pyGH-L292)
Let me know if something doesn't match the PR guidelines. This is my first PR in the python source code.

* bpo-39040: Fix parsing of email headers with encoded-words inside a quoted string.
It is fairly common to find malformed mime headers (especially content-disposition
headers) where the parameter values, instead of being encoded to RFC
standards, are "encoded" by doing RFC 2047 "encoded word" encoding, and
then enclosing the whole thing in quotes. The processing of these malformed
headers was incorrectly leaving the spaces between encoded words in the decoded
text (whitespace between adjacent encoded words is supposed to be stripped on
decoding). This changeset fixes the encoded word processing inside quoted strings
(bare-quoted-string) to do correct RFC 2047 decoding by stripping that
whitespace.

ctypes now raises an ArgumentError when a callback
is invoked with more than 1024 arguments.
The ctypes module allocates arguments on the stack in
ctypes_callproc() using alloca(), which is problematic
when large numbers of arguments are passed. Instead
of a stack overflow, this commit raises an ArgumentError
if more than 1024 parameters are passed.
