commit ca5b01f538c122dc1f0e989f5703c75b8cf8ca3a
Author: Kalle Olavi Niemitalo <address@hidden>

    rpctrace: Print beyond '\0' in MACH_MSG_TYPE_CHAR.
    
    This will now display the 'argv: data_t' argument of file_exec
    as e.g. "who\0am\0i\0" rather than just "who".  In contrast,
    the 'file_name: string_t' argument of dir_lookup will still be
    truncated at the first null character.
    
    The previous implementation might crash if an out-of-line
    char array exactly fills a page and does not contain any
    null characters.
    
    * utils/rpctrace.c (print_data): On MACH_MSG_TYPE_STRING and
    MACH_MSG_TYPE_CHAR, check for end of buffer before checking for a null
    character.  On MACH_MSG_TYPE_CHAR only, continue printing past null
    characters.
