  completely refactor accessctl (again)

  This time it's using an actual access control list system, rather than whatever
  it was doing before. The new system uses a Filter type, rather than Condition,
  to decide which acl element should have its action (allow or deny) applied. This
  makes testing way easier, since all the different matching conditions are now
  individual filters, and so are tested individually.
