bpo-44859: Improve error handling in sqlite3 and and raise more accurate exceptions. (GH-27654) 
* 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.

bpo-44839: Raise more specific errors in sqlite3 (GH-27613) 
MemoryError raised in user-defined functions will now preserve
its type. OverflowError will now be converted to DataError.
Previously both were converted to OperationalError.

bpo-42213: Remove redundant cyclic GC hack in sqlite3 (GH-26517) 
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

bpo-42213: Check connection in sqlite3.Connection.__enter__ (GH-26512) 
Try to harden connection close:

- add tests that exercise stuff against a closed database
- add wrapper for sqlite3_close_v2()
- check connection on __enter__
- explicitly free pending statements before close()
- sqlite3_close_v2() always returns SQLITE_OK
