Fix invalid function cast warnings with gcc 8
for method conventions different from METH_NOARGS, METH_O and
METH_VARARGS excluding Argument Clinic generated code.

* Remove Setup.config
* Always define WITH_THREAD for compatibility.

There was few cases of using literal 0 instead of NULL in the context of
pointers.  While this was a legitimate C code, using NULL rather than 0 makes
the code clearer.

Dates and version information from the changelog:

* 2006-08-12 (3.3.7) added SQLITE_CREATE_VTABLE, SQLITE_DROP_VTABLE
* 2006-10-09 (3.3.8) added SQLITE_FUNCTION
* 2009-01-12 (3.6.8) added SQLITE_SAVEPOINT
* 2014-02-03 (3.8.3) added SQLITE_RECURSIVE

Patch by Dingyuan Wang.

Directly pass NULL rather than an empty string.

Issue #13773: sqlite3.connect() gets a new `uri` parameter to pass the filename as a URI, allowing to pass custom options.

Closes #13921.

Thanks to Konrad Schöbel and Jasper Schulz for helping with the mass-editing.
