Subject: utils: implement settrans --pid-file
This switch makes settrans write the pid file of the active translator
it starts to a file. This makes the pid easily retrievable for test
suites.
* utils/settrans.c (options): Add --pid-file.
(main): Add variable pid_file.
(parse_opt): Handle --pid-file switch.
(open_node): Write pid file.
