@vstinner: with this PR, sqlite3 emits a ResourceWarning if close() was not called explicitly on a sqlite3.Connection object before it is deleted. I did not (yet) add a resource warning for the case where close fails (future enhancement).

As you can see from the test changes, we've been pretty lax with resource handling in the sqlite3 test suite 😆

UPDATE: Tests updated in gh-108017

LGTM. This change does what it says. There is room for enhancement, but it can be addressed separately (@erlend-aasland already creates issues to track remaining points).

Thanks for the review, Victor! I asked about #108015 (comment) on the core dev Discord. If it is an issue, we can fix it later.

I'll wait with merging until I've heard from @simonw and @felixxm, in case they've got opinions about this.

Note: I intend to add ResourceWarnings in case sqlite3_close*() fails as well, but I will do that in a follow-up PR. Currently, the sqlite3 module asserts that sqlite3_close*() did not fail, which is not optimal.

This change doesn't break anything important in Django 👍 (at the first glance). I've started fixing ResourceWarnings in our tests, check out django/django#17178.
