units: move a number of units into the tarball

relicense to LGPLv2.1 (with exceptions) We finally got the OK from all contributors with non-trivial commits to relicense systemd from GPL2+ to LGPL2.1+. Some udev bits continue to be GPL2+ for now, but we are looking into relicensing them too, to allow free copy/paste of all code within systemd. The bits that used to be MIT continue to be MIT. The big benefit of the relicensing is that closed source code may now link against libsystemd-login.so and friends.

Stop syslog.socket when entering emergency mode (#3130) When enabling ForwardToSyslog=yes, the syslog.socket is active when entering emergency mode. Any log message then triggers the start of rsyslog.service (or other implementation) along with its dependencies such as local-fs.target and sysinit.target. As these might fail themselves (e. g. faulty /etc/fstab), this breaks the emergency mode. This causes syslog.socket to fail with "Failed to queue service startup job: Transition is destructive". Add Conflicts=syslog.socket to emergency.service to make sure the socket is stopped when emergency.service is started. Fixes #266

units: do not throw a warning in emergency mode if plymouth is not installed (#5528) Ideally, plymouth should only be referenced via dependencies, not ExecStartPre's. This at least avoids the confusing error message on minimal installations that do not carry plymouth.

emergency.service: Don't say "Welcome" when it's an emergency (#3569) Quoting @cgwalters: Just uploading this as an RFC. Now I know reading the code that systemd says `Welcome to $OS` as a generic thing, but my initial impression on seeing this was that it was almost sarcastic =) Let's say "You are in emergency mode" as a more neutral/less excited phrase. This patch is based on #3556, but makes the same change for rescue mode.

ExecStartPre=-/bin/echo -e 'You are in emergency mode. After logging in, type "journalctl -xb" to view\\nsystem logs, "systemctl reboot" to reboot, "systemctl default" or ^D to\\ntry again to boot into default mode.'
Use "new" --job-mode= option in more places --irreversible/--ignore-dependencies/--fail are deprececated since 4dc5b821ae737914499119e29811fc3346e3d97c. Also add shell completions for --jobs-mode.

service: introduce Type=idle and use it for gettys Type=idle is much like Type=simple, however between the fork() and the exec() in the child we wait until PID 1 informs us that no jobs are left. This is mostly a cosmetic fix to make gettys appear only after all boot output is finished and complete. Note that this does not impact the normal job logic as we do not delay the completion of any jobs. We just delay the invocation of the actual binary, and only for services that otherwise would be of Type=simple.

units: direct stdout/stderr of rescue shells to tty With output of services going to syslog by default now, the rescue shell units need to direct their output to tty explicitly. Specify stderr too, just in case.
