Don't ignore errors raised by `PyErr_WarnFormat` in `warn_about_fork_with_threads`
Instead, ignore the warnings in all test code that forks. (That's a lot of functions.)
In `test_support`, make `ignore_warnings` a context manager (as well as decorator),
and add a `message` argument to it.
Also add a `ignore_fork_in_thread_deprecation_warnings` helper for the deadlock-in-fork
warning.
Add test annotations required to run the test suite on iOS (PEP 730).
The majority of the change involve annotating tests that use subprocess,
but are skipped on Emscripten/WASI for other reasons, and including
iOS/tvOS/watchOS under the same umbrella as macOS/darwin checks.
`is_apple` and `is_apple_mobile` test helpers have been added to
identify *any* Apple platform, and "any Apple platform except macOS",
respectively.
Add write_all() helper function to test_pty to raise an exception on
short write: if os.writes() does not write all bytes. It should not
happen for a PTY.
In 2003, test_pty got a hardcoded timeout of 10 seconds to prevent
hanging on AIX & HPUX "if run after test_openpty":
commit 7d8145268e. Since 2003, test_pty
was no longer reported to hang on AIX. But today, the test can fail
simply because a CI is busy running other tests in parallel.
The timeout of 10 seconds is no longer needed, just remove it.
Moreover, regrtest now has multiple built-in generic timeout
mecanisms.
Utilize new functions termios.tcgetwinsize() and termios.tcsetwinsize in test_pty.py.

On non-Linux POSIX platforms, like FreeBSD or macOS,
the FD used to read a forked PTY may signal its exit not
by raising an error but by sending empty data to the read
syscall. This case wasn't handled, leading to hanging
`pty.spawn` calls.

When stdin is a TTY, the test added in commit c13d89955d
is expected to fail. However, when it failed, it did not close
its file descriptors. This is flagged by the refleak tests (but
only when stdin is a TTY, which doesn't seem to be the case on CI).
test_builtin.PtyTests now registers an handler for SIGHUP signal.
Closing the PTY file descriptor can emit a SIGHUP signal: just ignore
it.
run_child() now also closes the PTY file descriptor before waiting
for the process completition, otherwise the test hangs on AIX.
Add os.waitstatus_to_exitcode() function to convert a wait status to an
exitcode.
Suggest waitstatus_to_exitcode() usage in the documentation when
appropriate.
Use waitstatus_to_exitcode() in:
* multiprocessing, os, subprocess and _bootsubprocess modules;
* test.support.wait_process();
* setup.py: run_command();
* and many tests.
Fix test_pty: if the process is the session leader, closing the
master file descriptor raises a SIGHUP signal: simply ignore SIGHUP
when running the tests.
* bpo-31158: Fix nondeterministic read in test_pty
* Reuse existing readline implementation from io.
Thx to @pitrou
* Updated comment
Ideally, this commit is fixuped into the previous commit. Since there is
already a comment on github, I won't rebase.
* bpo-31479: Always reset the signal alarm in tests
Use "try: ... finally: signal.signal(0)" pattern to make sure that
tests don't "leak" a pending fatal signal alarm.
* Move two more alarm() calls into the try block
Fix also typo: replace signal.signal(0) with signal.alarm(0)
* Move another signal.alarm() into the try block
I have compared output between pre- and post-patch runs of these tests
to make sure there's nothing missing and nothing broken, on both
Windows and Linux. The only differences I found were actually tests
that were previously *not* run.
