bpo-1635741: Add PyModule_AddObjectRef() function (GH-23122)
Added PyModule_AddObjectRef() function: similar to
PyModule_AddObjectRef() but don't steal a reference to the value on
success.

/* The API version is maintained (independently from the Python version)
so we can detect mismatches between the interpreter and dynamically
loaded modules. These are diagnosed by an error message but
the module is still loaded (because the mismatch can only be tested
after loading the module). The error message is intended to
explain the core dump a few seconds later.
The symbol PYTHON_API_STRING defines the same value as a string
literal. *** PLEASE MAKE SURE THE DEFINITIONS MATCH. ***

version change:
22-Feb-2006 MvL 1013 PEP 353 - long indices for sequence lengths
19-Aug-2002 GvR 1012 Changes to string object struct for
interning changes, saving 3 bytes.
17-Jul-2001 GvR 1011 Descr-branch, just to be on the safe side
25-Jan-2001 FLD 1010 Parameters added to PyCode_New() and
PyFrame_New(); Python 2.1a2
14-Mar-2000 GvR 1009 Unicode API added
3-Jan-1999 GvR 1007 Decided to change back! (Don't reuse 1008!)
3-Dec-1998 GvR 1008 Python 1.5.2b1
18-Jan-1997 GvR 1007 string interning and other speedups
11-Oct-1996 GvR renamed Py_Ellipses to Py_Ellipsis :-(
30-Jul-1996 GvR Slice and ellipses syntax added
23-Jul-1996 GvR For 1.4 -- better safe than sorry this time :-)
7-Nov-1995 GvR Keyword arguments (should've been done at 1.3 :-( )
10-Jan-1995 GvR Renamed globals to new naming scheme
9-Jan-1995 GvR Initial version (incompatible with older API)
