    libports: use protected payloads to optimize the object lookup
    
    * NEWS: Mention protected payloads.
    * libports/Makefile (SRCS): Add `port-deref-deferred.c'.
    * libports/create-internal.c (_ports_create_port_internal): Set the
    protected payload to the objects address.
    * libports/import-port.c (ports_import_port): Likewise.
    * libports/reallocate-from-external.c (ports_reallocate_from_external):
    Likewise.
    * libports/reallocate-port.c (ports_reallocate_port): Likewise.
    * libports/transfer-right.c (ports_transfer_right): Likewise.
    * libports/manage-multithread.c (ports_manage_port_operations_multithread):
    Use the protected payload for the object lookup if provided.  Add
    thread pool management calls.

    Likewise.
    * libports/destroy-right.c (ports_destroy_right): Defer the

    * libports/ports.h (struct port_bucket): New field `threadpool'.
