* bpo-45512: Raise sqlite3.Connection.__init__ is called with bad isolation level
* Also explicitly test allowed isolation levels
* Use subTest for better error messages if something goes wrong
* Update Lib/test/test_sqlite3/test_dbapi.py

* Move _PyObject_CallNoArgs() to pycore_call.h (internal C API).
* _ssl, _sqlite and _testcapi extensions now call the public
PyObject_CallNoArgs() function, rather than _PyObject_CallNoArgs().
* _lsprof extension is now built with Py_BUILD_CORE_MODULE macro
defined to get access to internal _PyObject_CallNoArgs().
Fix typo in the private _PyObject_CallNoArg() function name: rename
it to _PyObject_CallNoArgs() to be consistent with the public
function PyObject_CallNoArgs().
* Constructors of subclasses of some buitin classes (e.g. tuple, list,
frozenset) no longer accept arbitrary keyword arguments.
* Subclass of set can now define a __new__() method with additional
keyword parameters without overriding also __init__().
- all callbacks are now named xxx_callback
- normalise callable naming in set_*() functions
- normalise context argument naming in callbacks
The sqlite code is being "touched" in bpo-42064 (and related issues);
this style change makes it easier to work with and review.
- acquire the GIL at the very start[1]
- release the GIL at the very end
[1] The trace callback performs a sanity check before acquiring the GIL

* MemoryError is now raised instead of sqlite3.Warning when
memory is not enough for encoding a statement to UTF-8
in Connection.__call__() and Cursor.execute().
* UnicodEncodeError is now raised instead of sqlite3.Warning when
the statement contains surrogate characters
in Connection.__call__() and Cursor.execute().
* TypeError is now raised instead of ValueError for non-string
script argument in Cursor.executescript().
* ValueError is now raised for script containing the null
character instead of truncating it in Cursor.executescript().
* Correctly handle exceptions raised when getting boolean value
of the result of the progress handler.
* Add many tests covering different corner cases.

MemoryError raised in user-defined functions will now preserve
its type. OverflowError will now be converted to DataError.
Previously both were converted to OperationalError.
Prepare for module state:
- Add "get state by defining class" and "get state by module def" stubs
- Add AC defining class when needed
- Add state pointer to connection context
- Pass state as argument to utility functions

This implies that SQLite now takes care of destroying the callback
context (the PyObject callable it has been passed), so we can strip the
collation dict from the connection object.
