Some pty tests persistently hung on the AIX CI buildbots. Fix that by
adding a helper script that properly sets up the pty before spawning
the script under test.
On investigation I discovered that the test runner hung when it tried
to close the slave pty's file descriptor, probably due to a bug in
AIX's pty implementation. I could reproduce it with a short C program.
The test runner also leaked file descriptors to the child process.
I couldn't convince python's `subprocess.Popen()` to do what I wanted
it to do so I opted to move the logic to a helper script that can do
fork/setsid/etc. without having to worry about stomping on state in
tools/test.py.
In the process I also uncovered some bugs in the pty module of the
python distro that ships with macOS 10.14, leading me to reimplement
a sizable chunk of the functionality of that module.
And last but not least, of course there are differences between ptys
on different platforms and the helper script has to paper over that.
Of course.
Really, this commit took me longer to put together than I care to admit.
Caveat emptor: this commit takes the hacky ^D feeding to the slave out
of tools/test.py and puts it in the *.in input files. You can also feed
other control characters to tests, like ^C or ^Z, simply by inserting
them into the corresponding input file. I think that's nice.

The test is believed to no longer be unreliable on AIX. Remove the flaky
designation from the appropriate status file.

It's not wholly clear what commit introduced the regression but between
v8.4.0 and v8.5.0 the 'resize' event stopped getting emitted when the
tty was resized.
The SIGWINCH event listener apparently was being installed before the
support code for `process.on('SIGWINCH', ...)` was. Fix that by moving
said support code to real early in the bootstrap process.
This commit also seems to fix a Windows-only "write EINVAL" error for
reasons even less well-understood...

The tests in pseudo-tty takes the form of child node writing some data
and exiting, while parent python consume them through pseudo tty
implementations, and validate the result.
While there is no synchronization between child and parent, this works
for most platforms, except AIX, where the child exits even before the
parent could setup the read loop, under race conditions
Fixing the race condition is ideally done through sending ACK messages
to and forth, but involves massive changes and have side effect. The
workaround is to address them in AIX alone, by adding a reasonable
delay.

open for a while but the frequency of the failures
seems to be such that we should mark it as flaky

pseudo-tty/no_interleaved_stdio has hung a few times
in the last couple of days on AIX. We believe
it is not a Node.js issue but an issue with python
on AIX. Its being investigated under:

Excluding this additional test until we can
resolve the python issue.

We had marked it as flaky but in some failures it hangs
and does not seem to timeout, and or is reported as
an error.
Also add prefix to status file as it was missing.
Also fix name of status file in testcfg.py. It
was pointing to message.status instead of
pseudo-tty.status.
