Stop a crash in 66-init when it is used without any arguments.  argc is never 0 so the "if (!argc) " statement won't print the usage.

It works now. Use notifpipe uniquely when the catch-all logger is not created. Do not use auto_string on chained stralloc

add -z option. Pass new variable to rc.init file: CONTAINER, CATCHLOG, RCINIT_CONTAINER. Handle booting inside a container

change arguments to follow s6-svscan change: arguments are now start,stop,reload,nuke,zombies. add -d and -t for scandir start time

change interface: owner argument is now an option and argument are create|remove. The up option is splitted to 66-scanctl. add -B to boot inside a container. Add -c to not define a logger. Revamp write_control() function. Create new directory (default /run/66/scandir/container/) in case of container boot

remove deprecated option at s6-svc and switch -B -C (which is renamed -c) to be consistent with 66-scandir program
