Disallow control chars in http URLs in urllib2.urlopen. This
addresses a potential security problem for applications that do not
sanity check their URLs where http request headers could be injected.
Disable https related urllib tests on a build without ssl (GH-13032)
These tests require an SSL enabled build. Skip these tests when
python is built without SSL to fix test failures.
Use httplib.InvalidURL instead of ValueError as the new error case's
exception. (GH-13044)

Notes on backport to Python 2.7:
* test_urllib tests urllib.urlopen() which quotes the URL and so is
not vulerable to HTTP Header Injection.
* Add tests to test_urllib2 on urllib2.urlopen().
* Reject non-ASCII characters: range 0x80-0xff.
TLS 1.3 has a more efficient handshake protocol. The client can reject the server's credentials and close the connection before the server has even finished writing out all of its initial data. Depending on whether the server finishes writing the rest of its handshake before the it sees the connection is reset, the server will read an empty line or see a ECONNRESET OSError. Nothing is really wrong here with the server or client, so just suppress the error output in the OSError case to fix the test.
This fix isn't required in Python 3 because clients that reject the server's certificate will shut down the TLS layer before closing the TCP connection.
Modern Linux distros such as Debian Buster have default OpenSSL system
configurations that reject connections to servers with weak certificates
by default. This causes our test suite run with external networking
resources enabled to skip these tests when they encounter such a
failure.
Fixing the network servers is a separate issue.

Changes to test_ssl.py required as 2.7 has legacy protocol tests.
The test_httplib.py change is omitted from this backport as
self-signed.pythontest.net's certificate was updated and the
test_nntplib.py change is not applicable on 2.7.

* [2.7] bpo-36816: Update the self-signed.pythontest.net cert (GH-13192)
We updated the server, our testsuite must match.

The 2.7 tree also needed a certificate in the capath directory updated.
The filename for that was determined by `openssl x509 -in $cert.pem -subject_hash`.

bpo-28552, bpo-7774: Fix distutils.sysconfig if sys.executable is
None or an empty string: use os.getcwd() to initialize project_base.
Fix also the distutils build command: don't use sys.executable if
it's evaluated as false (None or empty string).
Fix reference leak hunting in regrtest: compute also deltas (of
reference count and file descriptor count) during warmup, to ensure
that everything is initialized before starting to hunt reference
leaks.
Other changes:
* Replace gc.collect() with support.gc_collect() in clear_caches()
* dash_R() is now more quiet with --quiet option (don't display
progress).
* Precompute the full range for "for it in range(repcount):" to
ensure that the iteration doesn't allocate anything new.
* dash_R() now is responsible to call warm_caches().
(cherry picked from commit 5aaac94eeb)
Remove the PyMem_FREE() call added in cb90c89. The buffer will be
freed when PyTokenizer_Free() is called on the tokenizer state.

The test test_customize_compiler() now mocks all sysconfig variables
and all environment variables used by customize_compiler().
(cherry picked from commit 72c7b372cf)
Fix CFLAGS in customize_compiler() of distutils.sysconfig: when the
CFLAGS environment variable is defined, don't override CFLAGS variable with
the OPT variable anymore.
