63003524cb *.localdomain != localhost
".localdomain" is not a reserved suffix (or prefix). I'm not aware of any
product expecting *.localdomain to resolve to localhost, however I am aware of
at least one product that defaults to ".localdomain" as its DNS suffix provided
via DHCP (pfSense). This leads to unexpected results when attempting to access
a host that's offline (or a host that's online, when nsswitch.conf is
[mis-]configured to have myhostname ahead of DNS).

Operate on:
localhost (and localhost.)
*.localhost (and *.localhost.)
localhost.localdomain (and localhost.localdomain.)
*.localhost.localdomain (and *.localhost.localdomain.)

We should not cover:
*.localdomain (nor *.localdomain.)
localdomain (nor localdomain.)

1ace2438c6 systemd-resolve: reword --help output
The output didn't specify if the default for --cname/--search/--legend and
other options was yes or no. Change the description to be explicit about that.

Also make the --help output and man page closer.

edb4843fbd man: show output in example systemd-resolve commands
I think example output allows the reader of the man page to
see what functionlity is provided without running the commands
themselves. Specific values in the examples are bound to get out
of date but this is not a problem.

stable for a while. It it a useful testing tool.

cf98937cc7 activate: allow multiple, possibly invalid, fd names
Previous code only allowed a single name to be passed, and duplicated
it over all descriptors. For the sake of testing, allow different
names and in arbitrary number. If just one is given, duplicate it
to match the number of sockets. This matches previuos behaviour.

Since this is a testing tool, it seems useful to allow passing invalid
names to test application behaviour with invalid names. Hence, only
warn. When warning, escape the name.

479050b363 core: drop Capabilities= setting
The setting is hardly useful (since its effect is generally reduced to zero due
to file system caps), and with the advent of ambient caps an actually useful
replacement exists, hence let's get rid of this.

I am pretty sure this was unused and our man page already recommended against
its use, hence this should be a safe thing to remove.

798c486fbc remove bus-proxyd
As kdbus won't land in the anticipated way, the bus-proxy is not needed in
its current form. It can be resurrected at any time thanks to the history,
but for now, let's remove it from the sources. If we'll have a similar tool
in the future, it will look quite differently anyway.

Note that stdio-bridge is still available. It was restored from a version
prior to f252ff17, and refactored to make use of the current APIs.

50f48ad37a cgroup: remove support for NetClass= directive
Support for net_cls.class_id through the NetClass= configuration directive
has been added in v227 in preparation for a per-unit packet filter mechanism.
However, it turns out the kernel people have decided to deprecate the net_cls
and net_prio controllers in v2. Tejun provides a comprehensive justification
for this in his commit, which has landed during the merge window for kernel
v4.5:

  https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=bd1060a1d671

As we're aiming for full support for the v2 cgroup hierarchy, we can no
longer support this feature. Userspace tool such as nftables are moving over
to setting rules that are specific to the full cgroup path of a task, which
obsoletes these controllers anyway.

This commit removes support for tweaking details in the net_cls controller,
but keeps the NetClass= directive around for legacy compatibility reasons.

eef0a274e6 activate: add a new switch --inetd to enable inetd-style socket activation
Previously, using --accept would enable inetd-style socket activation in addition to per-connection operation. This is
now split into two switches: --accept only switches between per-connection or single-instance operation. --inetd
switches between inetd-style or new-style fd passing.

This breaks the interface of the tool, but given that it is a debugging tool shipped in /usr/lib/systemd/ it's not
really a public interface.

This change allows testing new-style per-connection daemons.

6bf0f408e4 core: make the StartLimitXYZ= settings generic and apply to any kind of unit, not just services
This moves the StartLimitBurst=, StartLimitInterval=, StartLimitAction=, RebootArgument= from the [Service] section
into the [Unit] section of unit files, and thus support it in all unit types, not just in services.

This way we can enforce the start limit much earlier, in particular before testing the unit conditions, so that
repeated start-up failure due to failed conditions is also considered for the start limit logic.

For compatibility the four options may also be configured in the [Service] section still, but we only document them in
their new section [Unit].

This also renamed the socket unit failure code "service-failed-permanent" into "service-start-limit-hit" to express
more clearly what it is about, after all it's only triggered through the start limit being hit.

Finally, the code in busname_trigger_notify() and socket_trigger_notify() is altered to become more alike.

ce359e98f8 core: when a service's ExecStartPre= times out, skip ExecStop=
This makes sure we never run two control processes at the same time, we cannot keep track off.

This introduces a slight change of behaviour but cleans up the definition of ExecStop= and ExecStopPost=. The former is
now invoked only if the service managed to start-up correctly. The latter is called even if start-up failed half-way.
Thus, ExecStopPost= may be used as clean-up step for both successful and failed start-up attempts, but ExecStop='s
purpose is clearly defined as being responsible for shutting down the service and nothing else.

The precise behaviour of this was not documented yet. This commit adds the necessary docs.

7732f92bad nspawn: optionally run a stub init process as PID 1
This adds a new switch --as-pid2, which allows running commands as PID 2, while a stub init process is run as PID 1.
This is useful in order to run arbitrary commands in a container, as PID1's semantics are different from all other
processes regarding reaping of unknown children or signal handling.

393003e1de sd-event: permit a USEC_INFINITY timeout as an alternative to a disabling an event source
This should simplify handling of time events in clients and is in-line with the USEC_INFINITY macro we already have.
This way setting a timeout to 0 indicates "elapse immediately", and a timeout of USEC_INFINITY "elapse never".
