This change utilizes pytest-xdist to perform a multiproc test
run and reworks aurweb.db's code. We no longer use a global
engine, session or Session, but we now use a memo of engines
and sessions as they are requested, based on the PYTEST_CURRENT_TEST
environment variable, which is available during testing.
Additionally, this change strips several SQLite components
out of the Python code-base.
SQLite is still compatible with PHP and sharness tests, but
not with our FastAPI implementation.
More changes:
------------
- Remove use of aurweb.db.session global in other code.
- Use new aurweb.db.name() dynamic db name function in env.py.
- Added 'addopts' to pytest.ini which utilizes multiprocessing.
- Highly recommended to leave this be or modify `-n auto` to
`-n {cpu_threads}` where cpu_threads is at least 2.

instance without interrupting user code.
- Use aurweb.db.get_session() in session API methods
- Add docstrings to session API methods
- Refactor aurweb.db.delete
- Normalize aurweb.db.delete to an alias of session.delete
- Refresh instances in places we depend on their non-PK columns
being up to date.

Django uses a reference graph to determine the order
in table deletions that occur. Do the same here.
This commit also adds in the `REGEXP` sqlite function,
exactly how Django uses it in its reference graphing.

This is needed to avoid redundant objects in SQLAlchemy's
IdentityMap, since we pass a direct .execute to delete
the tables passed in. Additionally, remove our engine.connect()
call in favor of relying on the already-established Session.
