* 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.
With this, all sqlite3 static globals have been moved to the global state.
There are a couple of global static strings left, but there should be no need for adding them to the state.

Both `executescript` methods contain the same docstring typo:
_"Executes a multiple SQL statements at once."_ => _"Executes multiple SQL statements at once."_

Call SQLite API's first, and return early in case of error. At the end,
allocate the object and initialise members. We now avoid unneeded
alloc/dealloc's in case the statement creation fails.
The sqlite3 module now fully implements the GC protocol, so there's no
need for this workaround anymore.
- Add and use managed resource helper for connections using TESTFN
- Sort test imports
- Split open-tests into their own test case
