This makes 'status' behave like 'list-units':
systemctl status -> status of all units
systemctl -t error status -> status of error units
systemctl -t mount status -> etc.
It is not really necessary to have a hard requirement dependency on
systemd-journald.socket in almost every unit. The socket gets pulled
into boot via at least two ways:
sockets.target -> systemd-journald.socket
sysinit.target -> systemd-journald.service -> systemd-journald.socket
So just assume something pulled the socket in and drop the automatic
requirement dependencies on it.
"systemctl stop systemd-journald.socket" will now not take the whole
system down with it.
journald is supposed to work. Failure to connect to its socket implies
losing messages. It should be a very unusual event. Log the failure with
LOG_CRIT.
Just because this unit's stdout/stderr failed to connect to the journal
does not necessarily mean that we shouldn't try to log the failure using
a structured entry, so let's use log_struct_unit.
Almost every unit logs to the journal. If journald gets a permanent
failure, units would not be able to start (exit code 209/STDOUT).
Add a fallback to /dev/null to avoid making the system entirely
unusable in such a case.
write_to_journal() returns 0 if journal_fd is closed and nothing is
written. We need to make sure we'll try log_open_kmsg() then to make the
fallback work for "journal-or-kmsg".
Essentially transfer the 'README' file in src/bootchart to the man page
for easier reading by users.
Moved the 'History' section to the bottom, before the 'See Also' section.

systemd-nspawn will now print the PID of the child.
An example showing how to enter the container is added
to the man page.
Support for nsenter without an explicit command was
added in https://github.com/karelzak/util-linux/commit/5758069
(post v2.22.2). So this example requires both a new kernel
and the latest util-linux.
[zj: Reworded message s/to watch/to add watch on/ to make it clear
that it was the watch init action that failed, and not the
"process of watching". I think this way it'll be clearer to
people who don't know what inotify does.]
