faulthandler.enable(all_threads=True) dumps the tracebacks even if it is not
possible to get the state of the current thread
Create also the get_thread_state() subfunction to factorize the code.
* Write a new test to ensure that dump_tracebacks_later() still works if
it was already called and then cancelled before
* Don't use a variable to check the status of the thread, only rely on locks
* The thread only releases cancel_event if it was able to acquire it (if
the timer was interrupted)
* The main thread always hold this lock. It is only released when
faulthandler_thread() is interrupted until this thread exits, or at Python
exit.
The thread must not receive any signal. If the thread receives a signal,
sem_timedwait() is interrupted and returns EINTR, but in this case,
PyThread_acquire_lock_timed() retries sem_timedwait() and the main thread is
not aware of the signal. The problem is that some tests expect that the main
thread receives the signal, not faulthandler handler, which should be
invisible.
On Linux, the signal looks to be received by the main thread, whereas on
FreeBSD, it can be any thread.
* faulthandler_user() displays the tracebacks of all threads even if it is
unable to get the state of the current thread
* test_faulthandler: only release the GIL in test_gil_released() check
* create check_signum() subfunction
* faulthandler_cancel_dump_tracebacks_later() is responsible to set running
to zero (so we don't need the volatile keyword anymore)
* release locks if PyThread_start_new_thread() fails
assert(thread.running == 0) was wrong in a corner case
Always release the cancel join.
Fix also another corner case: _PyFaulthandler_Fini() called after setting
running variable to zero, but before releasing the join lock.
If the thread releases the join lock before the cancel lock, the thread may
sometimes still be alive at cancel_dump_tracebacks_later() exit. So the cancel
lock may be destroyed while the thread is still alive, whereas the thread will
try to release the cancel lock, which just crash.
Another minor fix: the thread doesn't release the cancel lock if it didn't
acquire it.

Fix formatting of values with embedded newlines when rfc2047 encoding
Before this patch if a value being encoded had an embedded newline,
the line following the newline would have no leading whitespace,
and the whitespace it did have was encoded into the word. Now
the existing whitespace gets turned into a blank, the way it does
in other header reformatting, and the _continuation_ws gets added
at the beginning of the encoded line.

#10960: fix 'stat' links, link to lstat from stat, general tidy of stat doc.
Original patch by Michal Nowikowski, with some additions and wording
fixes by me.
I changed the wording from 'Performs a stat system call' to 'Performs
the equivalent of a stat system call', since on Windows there are no
stat/lstat system calls involved. I also extended Michal's breakout
of the attributes into a list to the other paragraphs, and rearranged
the order of the paragraphs in the 'stat' docs to make it flow
better and put it in what I think is a more logical/useful order.

Also made similar changes to deque.reverse() though this wasn't

was more a matter of future-proofing.
zipimport uses ASCII encoding instead of cp497 to decode filenames, at
bootstrap, if the codec registry is not ready yet. It is still possible to have
non-ASCII filenames using the Unicode flag (UTF-8 encoding) for file entries in

Fix readinst() if file.read(n) returns a bytes object longer than n:
return -1 instead of the the buffer size to raise an exception.
Simplify also the function code.
function will now format any year when time.accept2dyear is false and
will accept years >= 1000 otherwise. The year range accepted by
time.mktime and time.strftime is still system dependent, but
time.mktime will now accept full range supported by the OS. Conversion
of 2-digit years to 4-digit is deprecated.
On Windows, set the binary mode on stdin, stdout, stderr and all
io.FileIO objects (to not translate newlines, \r\n <=> \n). The Python parser
translates newlines (\r\n => \n).

editline rl_initialize apparently discards any mappings done before it

readline, and then re-read the users .editrc (if any) afterward so they
can still override our defaults.
