Testing for a non-existing certificate file is already done in test_errors().
The wrongcert.pem test was originally testing behaviour with a mismatched
certificate.

Also add some more tests. Based on patch by Sye van der Veen.

functions: "s", "s*", "s#", "t#", "z", "z*", "z#", "w", "w*", "w#", "u",
"u#", "es", "et", "es#", "et#" and "c".

Augment htest to include all major IOBinding functions.

Issue #25907: Use {% trans %} tags in HTML templates to ease the translation of
the documentation. The tag comes from Jinja templating system, used by Sphinx.

Patch written by Julien Palard.

This was already done in the 3.5 branch; this just does the same in the 2.7
branch.

Issue #25843: When compiling code, don't merge constants if they are equal but
have a different types. For example, "f1, f2 = lambda: 1, lambda: 1.0" is now
correctly compiled to two different functions: f1() returns 1 (int) and f2()
returns 1.0 (int), even if 1 and 1.0 are equal.

Add a new _PyCode_ConstantKey() private function.

A single call to Pool.apply_async() will create only one process. To use all
of the pool's processes, it should be invoked multiple times:

    with Pool(processes=4) as pool:
        results = [pool.apply_async(func, ()) for i in range(4)]

This change helps to ignore text of PSF, BEOPEN.com and CNRI licenses when
translating the documentation. Patch written by Julien Palard who is
translating Python 3.5 doc to french. Text of other licenses already used
preformatted format.

Issue #24520: On FreeBSD, fpgetmask() was deprecated long time ago.
fedisableexcept() is now preferred.

non-UTF-8 encoding.

Initial patch for the backport by Alecsandru Patrascu.

Issue26017 - Suggest enclosing command args in double quotes when using characters which get interpreted by shell.

Re-encode CREDITS.txt to utf-8 and open it with 'utf-8'.

Issue26035 - Correct the argument names used in the docs of the traceback module. Make it consistent with module args.

Otherwise, GDB seems to affect the terminal's foreground process group,
interfering with test_ioctl, which does not expect the foreground process to
change during the test. This change also solves the problem of the tests
being stopped in the shell if test_gdb is run twice in parallel.

This is instead of svn.python.org, whose certificate recently expired, and
whose new certificate uses a different root certificate.

The certificate used at the pythontest server was modifed to set the "basic
constraints" CA flag. This flag seems to be required for test_get_ca_certs_
capath() to work.

Added the new self-signed certificate to capath with the following commands:

cp Lib/test/{selfsigned_pythontestdotnet.pem,capath/}
c_rehash -v Lib/test/capath/
c_rehash -v -old Lib/test/capath/
# Note the generated file names
cp Lib/test/capath/{selfsigned_pythontestdotnet.pem,0e4015b9.0}
mv Lib/test/capath/{selfsigned_pythontestdotnet.pem,ce7b8643.0}

When attempting to connect to port 444 on the new server, the resulting error
code is EHOSTUNREACH on Linux, and ETIMEDOUT on Windows.
