gh-89479: Export _Py_GetSpecializationStats() internal function (#92011) 
When Python is built with "./configure --enable-pystats" (if the
Py_STATS macro is defined), the _Py_GetSpecializationStats() function
must be exported, since it's used by the _opcode extension which is
built as a shared library.

gh-89373: _Py_Dealloc() checks tp_dealloc exception (#32357)

bpo-43998: Default to TLS 1.2 and increase cipher suite security (GH-25778) 
The ssl module now has more secure default settings. Ciphers without forward
secrecy or SHA-1 MAC are disabled by default. Security level 2 prohibits
weak RSA, DH, and ECC keys with less than 112 bits of security.
:class:`~ssl.SSLContext` defaults to minimum protocol version TLS 1.2.
Settings are based on Hynek Schlawack's research.
