Many users won't realise the implications the OpenSSL 1.0.2
minimum version requirement has when it comes to Ubuntu
14.04 and Debian 8, so expand on that in the platform support
section.

Also explicitly note the non-ASCII-based locale requirement for
full Unicode text handling support on non-Windows systems.

Increase the timeout from 1 min to 5 min.

Replace also time.time() with time.monotonic() for timeouts.
(cherry picked from commit 3ad8dec)

Co-authored-by: Pablo Galindo <Pablogsal@gmail.com>

The test failed on AMD64 Debian root 3.x buildbot because the busy
loop of 100 ms only increased time.thread_time() by 19.9 ms which is
smaller than 20 ms. Modify the test to tolerate a delta of at least
15 ms instead of 20 ms.

* bpo-34130: Fix test_signal.test_socket() (pythonGH-8326)

test_signal.test_socket(): On Windows, sometimes even if the C signal handler
succeed to write the signal number into the write end of the socketpair, the
test fails with a BlockingIOError on the non-blocking read.recv(1) because the
read end of the socketpair didn't receive the byte yet.

Fix the race condition on Windows by setting the read end as blocking.

(cherry picked from commit 99bb6df)

* bpo-34130: Fix test_signal.test_warn_on_full_buffer() (pythonGH-8327)

On Windows, sometimes test_signal.test_warn_on_full_buffer() fails to
fill the socketpair buffer. In that case, the C signal handler
succeed to write into the socket, it doesn't log the expected send
error, and so the test fail.

On Windows, the test now uses a timeout of 50 ms to fill the
socketpair buffer to fix this race condition.

Other changes:

* Begin with large chunk size to fill the buffer to speed up the
  test.
* Add error messages to assertion errors to more easily identify
  which assertion failed.
* Don't set the read end of the socketpair as non-blocking.

The test tries to fill the receiver's socket buffer and expects an
error. But the RDS protocol doesn't require that. Moreover, the Linux
implementation of RDS expects that the producer of the messages
reduces its rate, it's not the role of the receiver to trigger an
error.

The test fails on Fedora 28 by design, so remove it.

Py_Initialize() and Py_Main() cannot enable the C locale coercion
(PEP 538) anymore: it is always disabled. It can now only be enabled
by the Python program ("python3).

test_embed: get_filesystem_encoding() doesn't have to set PYTHONUTF8
nor PYTHONCOERCECLOCALE, these variables are already set in the
parent.
