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.
