Always pass -1, or INFTIM where defined, to the poll() system call when
a negative timeout is passed to the poll.poll([timeout]) method in the
select module. Various OSes throw an error with arbitrary negative
values.

Pattern `[a-z]` with `IGNORECASE` flag can match to some non-ASCII characters.
Straightforward solution for this is using `IGNORECASE | ASCII` flag.
But users may subclass `Template` and override only `idpattern`. So we want to
avoid changing `Template.flags`.
So this commit uses local flag `-i` for `idpattern` and change `[a-z]` to `[a-zA-Z]`.

When regrtest in run inside IDLE, sys.stdout and sys.stderr are not
TextIOWrapper objects and have no file descriptor associated:
sys.stderr.fileno() raises io.UnsupportedOperation.
Disable faulthandler and don't replace sys.stdout in that case.

With the upgrade of buildbot.python.org from Buildbot 0.8.x to 0.9.x,
the xmlrpc interface has been removed. This test is now skipped until
it can be rewritten to query a suitable substitute.

Fix test_exception_errpipe_bad_data() and
test_exception_errpipe_normal() of test_subprocess: mock os.waitpid()
to avoid calling the real os.waitpid(0, 0) which is an unexpected
side effect of the test.

This was possible before. GH-1560 introduced a regression after 3.6.2 got
released where only sequences were accepted now. This commit addresses this
problem.

Class execution requires that __prepare__() methods return
a proper execution namespace. Check for that immediately
after calling __prepare__(), rather than passing it through
to the code execution machinery and potentially triggering
SystemError (in debug builds) or a cryptic TypeError
(in release builds).
Patch by Oren Milman.
(cherry picked from commit 5837d0418f)
Some objects (like test mocks) auto-generate new objects on
attribute access, which can lead to an infinite loop in
inspect.unwrap().
Ensuring references are retained to otherwise temporary objects
and capping the size of the memo dict turns this case into a
conventional exception instead..

Previously ensurepip would always report success, even if the
pip installation failed.

* Update version changed notice for backport
* bpo-31499, xml.etree: Fix xmlparser_gc_clear() crash
xml.etree: xmlparser_gc_clear() now sets self.parser to NULL to prevent a
crash in xmlparser_dealloc() if xmlparser_gc_clear() was called previously
by the garbage collector, because the parser was part of a reference cycle.

* bpo-31234: Join threads in tests (#3572)
Call thread.join() on threads to prevent the "dangling threads"
warning.

* bpo-31234: Join threads in test_hashlib (#3573)
* bpo-31234: Join threads in test_hashlib
Use thread.join() to wait until the parallel hash tasks complete
rather than using events. Calling thread.join() prevent "dangling
thread" warnings.

* Avoid calling "PyObject_GetAttrString()" (and potentially executing user code) with a live exception set.
* Ignore only AttributeError on attribute lookups in ElementTree.XMLParser() and propagate all other exceptions.

This makes the default behavior (without specifying `globalns` manually) more
predictable for users, finds the right globalns automatically.
Implementation for classes assumes has a `__module__` attribute and that module
is present in `sys.modules`. It does this recursively for all bases in the
MRO. For modules, the implementation just uses their `__dict__` directly.
This is backwards compatible, will just raise fewer exceptions in naive user
code.

Some of the proxied methods use internal Logger state which isn't proxied,
causing failures if an adapter is applied to another adapter.
This commit fixes the issue, adds a new test for the use case.

ProcessPoolShutdownTest.test_del_shutdown() now closes the call queue
and joins its thread, to prevent leaking a dangling thread.
(cherry picked from commit 3bcf157c11)
* test_thread.test_forkinthread() now waits until the thread completes.
* Check the status in the test method, not in the thread function
* Don't ignore RuntimeError anymore: since the commit
346cbd351e (bpo-16500,
os.register_at_fork(), os.fork() cannot fail anymore with
RuntimeError.
* Replace 0.01 literal with a new POLL_SLEEP constant
* test_forkinthread(): test if os.fork() exists rather than testing
the platform.
