bpo-25720: Fix the method for checking pad state of curses WINDOW (GH-4164) (#4213)
Modify the code to use ncurses is_pad() instead of checking WINDOW
_flags field. If your platform does not provide the is_pad(), the
existing way that checks the field will be enabled.
Note: This change does not drop support for platforms where do not
have both WINDOW _flags field and is_pad().

test_curses now saves/restores signals. On FreeBSD, the curses module
sets handlers of some signals, but don't restore old handlers when
the module is deinitialized.
GCC says:
../cpython/Python/marshal.c: In function ‘PyMarshal_WriteLongToFile’:
../cpython/Python/marshal.c:70:35: warning: ‘wf.ptr’ may be used uninitialized in this function [-Wmaybe-uninitialized]

This isn't a real problem because if the file pointer is not NULL, the
string-related fields are never touched. But, it doesn't hurt to set the unused
fields to NULL.

TLS 1.3 introduces a new, distinct set of cipher suites. The TLS 1.3
cipher suites don't overlap with cipher suites from TLS 1.2 and earlier.
Since Python sets its own set of permitted ciphers, TLS 1.3 handshake
will fail as soon as OpenSSL 1.1.1 is released. Let's enable the common
AES-GCM and ChaCha20 suites.
Additionally the flag OP_NO_TLSv1_3 is added. It defaults to 0 (no op) with
OpenSSL prior to 1.1.1. This allows applications to opt-out from TLS 1.3
now.

bpo-27448: Work around a gc.disable race condition in subprocess. (#1932)
* bpo-27448: Work around a gc.disable race condition in subprocess.
This works around a gc.isenabled/gc.disable race condition in the 2.7
subprocess module by using a lock for the critical section. It'll
prevent multiple simultaneous subprocess launches from winding up with
gc remaining disabled but it can't fix the ultimate problem: gc enable
and disable is a global setting and a hack.
Users are *strongly encouraged* to use subprocess32 from PyPI instead
of the 2.7 standard library subprocess module. Mixing threads with
subprocess is a recipie for disaster otherwise even with "fixes" to
ameliorate common issues like this.
The ssl and hashlib modules now call OPENSSL_add_all_algorithms_noconf() on

Concerns to address:
The initial commit for NPN support into OpenSSL [1], had the
OPENSSL_NPN_* variables defined inside the OPENSSL_NO_NEXTPROTONEG
guard. The question is if that ever made it into a release.
