The s_get() function leaks the result variable on low memory.
Partially backport commit 19b52545
to fix it.

Fix linuxaudiodev.linux_audio_device() error handling:
close the internal file descriptor if it fails to open the device.

Use test_support.TEST_HTTP_URL (pythontest.net) instead of http://www.example.com/.

Fix off-by-one bug in cPickle that caused it to use uninitialised memory on truncated pickles read from FILE*s.

Fix two unlikely reference leaks in _hashopenssl. The leaks only occur in
out-of-memory cases. Thanks to Charalampos Stratakis.

Did you know an API documented as printing the pending traceback would sometimes exit the process?

You do now.

The standard math library (libm) may follow IEEE-754 recommendation to
include an implementation of sinPi(), i.e. sinPi(x):=sin(pi*x).
And this triggers a name clash, found by FreeBSD developer
Steve Kargl, who worked on putting sinpi into libm used on FreeBSD
(it has to be named "sinpi", not "sinPi", cf. e.g.
https://en.cppreference.com/w/c/experimental/fpext4).

Per POSIX, `nice(3)` requires `unistd.h` and `exit(3)` requires `stdlib.h`.

Fixing the test will prevent false positives with pedantic compilers like clang.

multissltests: fix _build_src(), add 'cwd' variable.

Backport of TLS 1.3 related fixes from 3.7.

Misc fixes and workarounds for compatibility with OpenSSL 1.1.1 from git
master and TLS 1.3 support. With OpenSSL 1.1.1, Python negotiates TLS 1.3 by
default. Some test cases only apply to TLS 1.2.

OpenSSL 1.1.1 has added a new option OP_ENABLE_MIDDLEBOX_COMPAT for TLS
1.3. The feature is enabled by default for maximum compatibility with
broken middle boxes. Users should be able to disable the hack and CPython's test suite needs
it to verify default options

Partial backport from cb5b68abCo-authored-by: Christian Heimes <christian@python.org>

The options OP_NO_COMPRESSION, OP_CIPHER_SERVER_PREFERENCE,
OP_SINGLE_DH_USE, OP_SINGLE_ECDH_USE, OP_NO_SSLv2 (except
for PROTOCOL_SSLv2), and OP_NO_SSLv3 (except for PROTOCOL_SSLv3)
are set by default. The initial cipher suite list contains only
HIGH ciphers, no NULL ciphers and MD5 ciphers (except for PROTOCOL_SSLv2).

(cherry picked from commit 358cfd42)

Change TLS 1.3 cipher suite settings for compatibility with OpenSSL
1.1.1-pre6 and newer. OpenSSL 1.1.1 will have TLS 1.3 cipers enabled by
default.

Also update multissltests to test with latest OpenSSL.
