    net/if_dl.h: make self-contained
    
    include <sys/_types.h> for u_char and u_short.
    
    to avoid including <sys/types.h>, remove the caddr_t cast from LLADDR.
    we are trying to get rid of caddr_t anyway, and since sdl_data is
    already an array of char, the cast is unnecessary.  this also makes
    LLADDR const-correct, i.e. passing a const sockaddr_dl will return a
    const pointer.
