Restrict functionality when ACLs are misconfigured.
This patch has two main purposes:
1) Improve warning messages when ACLs are configured improperly.
2) Prevent misconfigured ACLs from allowing potentially unwanted
traffic.
To acomplish point (2) in most cases, whatever configuration object that
the ACL belonged to was not allowed to load.
The one exception is res_pjsip_acl. In that case, ACLs are their own
configuration object. Furthermore, the module loading code has no
indication that a ACL configuration had a failure. So the tactic taken
here is to create an ACL that just blocks everything.
