Summary:
Shares of the same role (e.g. viewer) at different levels could interact for a resource (e.g. a doc) shared with everyone@, potentially blocking the listing of that resource. This diff removes the interaction.
The permission of a user on a resource is calculated by finding all acl rules that link that resource to a group to which the user belongs, or to a group that has a subgroup to which the user belongs, etc, and then bitwise-or-ing the permissions on the acl rules. A later wrinkle was to allow public sharing via special users. A still later wrinkle was to avoid listing resources if they were only shared with the special everyone@ user, while allowing access to them if user has their full link. That wrinkle had a bug, where if e.g. a doc were shared with everyone@ as a viewer, and the org the doc was in was shared with someone@ as a viewer, and the doc inherited the org permissions via a workspace, then that doc would end up not being listed.
The fix is straightforward enough, but needs different code for postgres and sqlite, and is a bit verbose because we unwrap subgroups to a few levels rather than doing recursion (which looks cleaner but was slower in benchmarks).
Test Plan: added test that fails without this fix

Summary:
Currently if I share a doc with a friend, and then soft-delete a doc
in the same workspace, that friend will see the workspace in their
trash (empty, but there).
This adds a test for the issue and resolves it by filtering out
docs at the sql level that used to be filtered out by javascript.
Test Plan: added test; existing tests pass

Summary: This moves enough server material into core to run a home server. The data engine is not yet incorporated (though in manual testing it works when ported).
