[interface] Provide the ability to shut down multiple interfaces
Shutting down (and optionally restarting) multiple interfaces is
fraught with problems if there are loops in the interface connectivity
(e.g. the HTTP content-decoded and transfer-decoded interfaces, which
will generally loop back to each other). Various workarounds
currently exist across the codebase, generally involving preceding
calls to intf_nullify() to avoid problems due to known loops.
Provide intfs_shutdown() and intfs_restart() to allow all of an
object's interfaces to be shut down (or restarted) in a single call,
without having to worry about potential external loops.
