    trans/crash: core file name templates
    
    Add an option to specify a template used to construct core file names.
    This way core files can be collected at a predictable central
    location.
    
    * hurd/crash.defs (crash_dump_task): Return EEXIST if the core file
    has been written elsewhere.
    * trans/crash.c (corefile_template): New variable.
    (template_valid): New function.
    (template_make_file_name): Likewise.
    (S_crash_dump_task): Use the template to construct a name, open the
    file, and write the core dump there instead of the handle provided by
    the caller.
    (argp_option): New option.
    (doc): Document the format.
    (parse_opt): Handle new option
    (trivfs_append_args): Likewise.
