This makes working with complexly structured documents easy
and more reliable as the parser is not susceptible to
element re-ordering.
Also fixes a bug when the tokenizer would choke after reading
a number.
Previously, if a service A depended on a service B via Requires=, and A
was not running and B restarted this would trigger a start of A as well,
since the restart was propagated as restart independently of the state
of A.
This patch ensures that a restart of B would be propagated as a
try-restart to A, thus not changing its state if it isn't up.

This reverts the primary effect of be7d9ff730.
After all Requisite= should be close to Requires=, without the one
exception that it doesn't pull in dependencies on start. However,
reverse deps on stop/restart should be treated the same way as for
Restart=, and this is already documented in the man page, hence stick to
it.

No distro ships that old systemd versions anyway, hence let's drop
support for live-upgrades for them. Offline updates are still supported.
And live-upgrades will only lose the job queue, hence basically still
work...
Change device_found_node() to also create a .device unit if a device is not
known by udev; this is the case for "tentative" devices picked up by mountinfo
(DEVICE_FOUND_MOUNT). With that we can record the "found" attribute on the
unit.
Change device_setup_unit() to also accept a NULL udev_device, and don't
add the extra udev information in that case.
Previously device_found_node() would not create a .device unit, and
unit_add_node_link() would then create a "dead" stub one via
manager_load_unit(), so we lost the "found" attribute and unmounted everything
from that device.

The hostname(1) tool allows comments in /etc/hostname. Introduce a new
read_hostname_config() in hostname-util which reads a hostname configuration
file like /etc/hostname, strips out comments, whitespace, and cleans the
hostname. Use it in hostname-setup.c and hostnamed and remove duplicated code.
Update hostname manpage. Add tests.

All functions should either log the errors they run into, or only return
them in which case the caller should log them.
Make sure this rule is followed, so that each error is logged precisely
once, and neither never, nor more than once.
This method should greatly improve offset based lookup, by simply jumping
from one boot to the next boot. It starts at the journal head to get the
a boot ID, makes a _BOOT_ID match and then comes from the opposite
journal direction (tail) to get to the end that boot. After flushing the matches
and advancing the journal from that exact position, we arrive at the start
of next boot. Rinse and repeat.
This is faster than the old method of aggregating the full boot listing just
so we can jump to a specific boot, which can be a real pain on big journals
just for a mere "-b -1" case.
As an additional benefit --list-boots should improve slightly too, because
it does less seeking.
Note that there can be a change in boot order with this lookup method
because it will use the order of boots in the journal, not the realtime stamp
stored in them. That's arguably better, though.
Another deficiency is that it will get confused with boots interleaving in the
journal, therefore, it will refuse operation in --merge, --file and --directory mode.

We were returning rather than continuing in some cases. The intention
was always to fully process all pending events before returning
from the SIGCHLD handler. Restore this behaviour.
When systemd-nspawn gets exec*()ed, it inherits the followings file
descriptors:
- 0, 1, 2: stdin, stdout, stderr
- SD_LISTEN_FDS_START, ... SD_LISTEN_FDS_START+LISTEN_FDS: file
descriptors passed by the system manager (useful for socket
activation). They are passed to the child process (process leader).
- extra lock fd: rkt passes a locked directory as an extra fd, so the
directory remains locked as long as the container is alive.
systemd-nspawn used to close all open fds except 0, 1, 2 and the
SD_LISTEN_FDS_START..SD_LISTEN_FDS_START+LISTEN_FDS. This patch delays
the close just before the exec so the nspawn process (parent) keeps the
extra fds open.
This patch supersedes the previous attempt ("cloexec extraneous fds"):
