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.
