    utils/rpctrace: fix output so that replies can be attributed to requests
    
    Currently, it is impossible to properly attribute response messages to
    requests.  Even though rpctrace is single-threaded, its tracee may
    not.  Or there might be more than one tracee.  In any such case it is
    not guaranteed that the reply message we just processed is for the
    request we just printed.  Fix this by printing ellipsis with the port
    name, so that reply messages can be properly attributed:
    
    task129(pid3312)->mach_port_allocate (3) ...134
    task129(pid3312)->mach_port_deallocate (pn{  1}) ...160
    134... = 0 pn{ 30}
    160... = 0
    
    * utils/rpctrace.c (last_reply_port): New variable.
    (print_ellipsis): New function.
    (print_request_header): Optionally print ellipsis and update
    last_reply_port.
    (print_reply_header): Likewise.

    utils/rpctrace: escape non-printable characters in strings
    
    * utils/rpctrace.c (escape_sequences): New char array mapping
    characters to their escape sequence.
    (print_data): Escape non-printable characters when printing strings.

    utils/rpctrace: handle MACH_MSG_TYPE_PORT_SEND rights in trace_and_forward
    
    This allows one to rpctrace processes doing select(2).
    
    * utils/rpctrace.c (trace_and_forward): Handle MACH_MSG_TYPE_PORT_SEND
    rights.

    utils/rpctrace: generalize tracing code
    
    Currently, rpctrace dies if a tracee uses select(2) because it asserts
    that reply_type is a MACH_MSG_TYPE_PORT_SEND_ONCE right.  Generalize
    the code surrounding the failing assertion.
    
    * utils/rpctrace.c (trace_and_forward): Generalize code by switching
    over reply_type.

    utils/rpctrace: generalize code in rewrite_right
    
    * utils/rpctrace.c (rewrite_right): Generalize the code so we can use
    rewrite_right to rewrite MACH_MSG_TYPE_PORT_SEND rights for non-rpc ports.
