- The passed max_length is also applied to the "comm" name, if comm_fallback is
  set.

- The right thing happens if max_length == 1 is specified

- when the cmdline "foobar" is abbreviated to 6 characters the result is not
  "foobar" instead of "foo...".

- trailing whitespace are removed before the ... suffix is appended. The 7
  character abbreviation of "foo barz" is hence "foo..." instead of "foo ...".

- leading whitespace are suppressed from the cmdline

systemctl: prolong timeout of "systemctl daemon-reload"

Reloading or reexecuting PID 1 means the unit generators are rerun, which are
timed out at 90s. Make sure the method call asking for the reload is timed out
at twice that, so that the generators have 90s and the reload operation has 90s
too.

This reworks the daemon_reload() call in systemctl, and makes it exclusively
about reloading/reexecing. Previously it was used for other trivial method
calls too, which didn't really help readability. As the code paths are now
sufficiently different, split out the old code into a new function
trivial_method().

This call also does a similar change as

nspawn: introduce --notify-ready=[no|yes] (#3474)

This the patch implements a notificaiton mechanism from the init process
in the container to systemd-nspawn.
The switch --notify-ready=yes configures systemd-nspawn to wait the "READY=1"
message from the init process in the container to send its own to systemd.
--notify-ready=no is equivalent to the previous behavior before this patch,
systemd-nspawn notifies systemd with a "READY=1" message when the container is
created. This notificaiton mechanism uses socket file with path relative to the contanier
"/run/systemd/nspawn/notify". The default values it --notify-ready=no.
It is also possible to configure this mechanism from the .nspawn files using
NotifyReady. This parameter takes the same options of the command line switch.

Before this patch, systemd-nspawn notifies "ready" after the inner child was created,
regardless the status of the service running inside it. Now, with --notify-ready=yes,
systemd-nspawn notifies when the service is ready. This is really useful when
there are dependencies between different contaniers.

Fixes https://github.com/systemd/systemd/issues/1369
Based on the work from https://github.com/systemd/systemd/pull/3022

Testing:
Boot a OS inside a container with systemd-nspawn.
Note: modify the commands accordingly with your filesystem.

1. Create a filesystem where you can boot an OS.
2. sudo systemd-nspawn -D ${HOME}/distros/fedora-23/ sh
2.1. Create the unit file /etc/systemd/system/sleep.service inside the container
     (You can use the example below)
2.2. systemdctl enable sleep
2.3 exit
3. sudo systemd-run --service-type=notify --unit=notify-test
   ${HOME}/systemd/systemd-nspawn --notify-ready=yes
   -D ${HOME}/distros/fedora-23/ -b
4. In a different shell run "systemctl status notify-test"

When using --notify-ready=yes the service status is "activating" for 20 seconds
before being set to "active (running)". Instead, using --notify-ready=no
the service status is marked "active (running)" quickly, without waiting for
the 20 seconds.

This patch was also test with --private-users=yes, you can test it just adding it
at the end of the command at point 3.

- sd-ndisc now exposes an sd_ndisc_router object that encapsulates a full RA
  message, and has direct, friendly acessor functions for the singleton RA
  properties, as well as an iterative interface to iterate through known and
  unsupported options. The router object may either be retrieved from the wire,
  or generated from raw data. In many ways the sd-ndisc API now matches the
  sd-lldp API, except that no implicit database of seen data is kept. (Note
  that sd-ndisc actually had a half-written, but unused implementaiton of such
  a store, which is removed now.)

- sd-ndisc will now collect the reception timestamps of RA, which is useful to
  make sd_ndisc_router fully descriptive of what it covers.

Fixes: #1079
