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.

Fix a NULL pointer deref in ssl module. The cert parser did not handle CRL
distribution points with empty DP or URI correctly. A malicious or buggy
certificate can result into segfault.

Due to regressions found with using Tk 8.6.9.1, build the python.org
macOS installers with Tcl/Tk 8.6.8 as used in previous releases.

This addresses C extension build errors related to an undefined _hypot
symbol when building with the Microsoft Visual C++ Compiler for Python
2.7 [1] or MinGWPy [2]. It also addresses errors when building a C++
extension with MinGWPy and C++11 from cmath, 'error "::hypot' has not
been declared'

In _localemodule.c and selectmodule.c, remove dead code that would
cause double decrefs if run.

In addition, replace PyList_SetItem() with PyList_SET_ITEM() in cases
where a new list is populated and there is no possibility of an error.

In addition, check if the list changed size in the loop in array_array_fromlist().
