sqlite3.iterdump() depends on the row factory returning resulting rows
as tuples; it will fail with custom row factories like for example a
dict factory.
With this commit, we explicitly reset the row factory of the cursor used
by iterdump(), so we always get predictable results. This does not
affect the row factory of the parent connection.

Add optional 'filter' parameter to iterdump() that allows a "LIKE"
pattern for filtering database objects to dump.

sqlite3.Connection.iterdump now ensures that foreign key support is
disabled before dumping the database schema, if there is any foreign key
violation.

Refactor the CLI so we can easily invoke it and mock command-line
arguments. Adapt the CLI tests so we no longer have to launch a
separate process.
Disable the busy handler for all concurrency tests; we have full
control over the order of the SQLite C API calls, so we can safely
do this.
The sqlite3 test suite now completes ~8 times faster than before.

Modify managed_connect() helper to support in-memory databases. Use it
for the regression tests added in GH-27844.

* 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.
1. Rewrite ThreadTests with a _run_test() helper method that does the heavy lifting
2. Add test.support.threading_helper.reap_threads to _run_test()
3. Use _run_test() in all threading tests
4. Add test case for sqlite3.Connection.set_trace_callback
5. Add test case for sqlite3.Connection.create_collation
