    x86_64: Support 8 byte inlined port rights to avoid message resizing.
    
    If a port is inlined in a message, the user has to use
    mach_port_name_inlined_t to define each port. Out of line memory
    continues to use mach_port_name_t since that memory has to be copied to
    the kernel anyway.
    
    Both copyinmsg and copyoutmsg can be reduced to nothing (if we ignore
    USER32) as a follow up but kept this patch simple for ease of review.

    Reorder mach_msg_type_t fields to ensure msgt_name and msgt_size are byte 
aligned
    
    msgt_unused appears right after msgt_size since msgt_size can be reduced
    to only 8 bits in the future, so we leave the door opened to make
    msgt_unused 13 bits long.
