libports: lock-less reference counting for port_info objects
* libports/ports.h (struct port_info): Use the new type.
* libports/lookup-port.c: No need to lock _ports_lock anymore.
* libports/bucket-iterate.c: Likewise.
* libports/complete-deallocate.c: Check if someone reacquired a
reference through a hash table lookup.
* libports/create-internal.c: Use the new reference counting primitives.
* libports/get-right.c: Likewise.
* libports/import-port.c: Likewise.
* libports/port-deref-weak.c: Likewise.
* libports/port-deref.c: Likewise.
* libports/port-ref-weak.c: Likewise.
* libports/port-ref.c: Likewise.
* libports/reallocate-from-external.c: Likewise.
* libports/transfer-right.c: Likewise.
* utils/rpctrace.c: Likewise.
