ef3100e963 machinectl: extend the "shell" syntax to take user@container names
In order to make "machinectl shell" more similar to ssh, allow the
following syntax to connect to a container under a specific username:

        machinectl shell lennart@fedora

Also beefs up related man page documentation.

91913f584a machinectl: make machine name parameters for "shell" and "login" optional

4289c3a725 machined: beef up PolicyKit actions
Introduce separate actions for creating login or shell sessions for
the local host or a local container. By default allow local unprivileged
clients to create new login sessions (which is safe, since getty will
ask for username and authentication).

Also, imply login privs from shell privs, as well as shell and login
privs from manage privs.

b04c25f9ef systemctl: properly handle empty control group paths in "status"
When showing the status of the "-.slice" slice root unit (whose reported
cgroup path is ""), we suppressed the cgroup tree so far, because
skipped it for all unit with an empty cgroup path. Let's fix that, and
properly handle the empty cgroup path.

fee6d013d8 machinectl: don't show ".host" pseudo-machine in list by default
Let's hide all machines whose name begins with "." by default, thus
hiding the ".host" pseudo-machine, unless --all is specified. This
takes inspiration from the ".host" image handling in "machinectl
list-images" which also hides all images whose name starts with ".".

fbe550738d machined: introduce pseudo-machine ".host" refererring to the host system
Some of the operations machined/machinectl implement are also very
useful when applied to the host system (such as machinectl login,
machinectl shell or machinectl status), hence introduce a pseudo-machine
by the name of ".host" in machined that refers to the host system, and
may be used top execute operations on the host system with.

This copies the pseudo-image ".host" machined already implements for
image related commands.

(This commit also adds a PK privilege for opening a PTY in a container,
which was previously not accessible for non-root.)

b9a8d25081 machined: validate machine names at more places
When enumerating machines from /run, and when accepting machine names
for operations, be more strict and always validate.

Note that these checks are strictly speaking unnecessary, since
enumeration happens only on the trusted /run...

25300b5a1f util: make machine_name_is_valid() a macro and move it to hostname-util.h
As it turns out machine_name_is_valid() does the exact same thing as
hostname_is_valid() these days, as it just invoked that and checked the
name length was < 64. However, hostname_is_valid() checks the length
against HOST_NAME_MAX anyway (which is 64 on Linux), hence any
additional check is redundant.

We hence replace machine_name_is_valid() by a macro that simply maps it
to hostname_is_valid() but sets the allow_trailing_dot parameter to
false. We also move this this call to hostname-util.h, to the same place
as the hostname_is_valid() declaration.

077c8c366b machined: always look for leader PID first
When looking for the machine belonging to a PID, always look for the
leader first, only then fall back to a cgroup check. We keep direct
track of the leader PID, but only indirectly of the cgroup, hence prefer
the PID.

49af9e1368 machined: add new OpenShell() bus call
This new bus call opens an interactive shell in a container. It works
like the existing OpenLogin() call, but does not involve getty, and
instead opens an arbitrary command line.

This is similar to "systemd-run -t -M" but is controlled by a specific
PolicyKit privilege.

023a4f6701 core: optionally create LOGIN_PROCESS or USER_PROCESS utmp entries
When generating utmp/wtmp entries, optionally add both LOGIN_PROCESS and
INIT_PROCESS entries or even all three of LOGIN_PROCESS, INIT_PROCESS
and USER_PROCESS entries, instead of just a single INIT_PROCESS entry.

With this change systemd may be used to not only invoke a getty directly
in a SysV-compliant way but alternatively also a login(1) implementation
or even forego getty and login entirely, and invoke arbitrary shells in
a way that they appear in who(1) or w(1).

This is preparation for a later commit that adds a "machinectl shell"
operation to invoke a shell in a container, in a way that is compatible
with who(1) and w(1).

1105ea51a8 sd-bus: don't list activators as proper peers
If a connection passed KDBUS_HELLO_ACTIVATOR, it cannot do I/O on the
bus. Hence, we should not treat it as proper peer. To actually query it,
you have to explicitly ask for activators.

This makes kdbus in-line with what dbus-daemon does.

f2196cf2e2 Revert "sd-bus: include queried path in GetManagedObjects"
This reverts commit 92d16a53e3. As it turns
out, this is not how ObjectManager is supposed to work. It is just a
special behavior of BlueZ, but no-one else implements it this way.

Revert the patch as discussed on github, and as such revert to the
previous behavior (as described in the spec).

9a9c7dc2cb sd-device: fix enumeration of devices without subsystem
Prior to commit c32eb440ba, libudev's
function udev_enumerate_scan_devices() had behaved differently. If
parent match was added with udev_enumerate_add_match_parent(),
udev_enumerate_scan_devices() did not return error if some child devices
had no subsystem symlink in sysfs. An example of such devices is USB
endpoints /sys/bus/usb/devices/*/ep_*. If there was a parent match
against USB device, old implementation of udev_enumerate_scan_devices()
did not treat ep_* device directories without subsystem symlink as error
and just ignored them, but new implementation returns -ENOENT (also
ignoring these devices) though correctly enumerates all other matching
devices.

To compare, you could look at 96df036fe3,
in src/libudev/libudev-enumerate.c, function parent_add_child():

    if (!match_subsystem(enumerate, udev_device_get_subsystem(dev)))
            goto nomatch;

udev_device_get_subsystem() was returning NULL, match_subsystem() was
returning false, and USB endpoint device was ignored.

New parent_add_child() from src/libsystemd/sd-device/device-enumerator.c
checks return value of sd_device_get_subsystem() and fails if subsystem
was not found. Absence of subsystem symlink should not be really treated
as error because all enumerations of children of USB devices will fail
with -ENOENT. This new behavior also breaks system-config-printer.

So restore old behavior and treat absence of subsystem symlink as no
match.

f52e61da04 resolved: only maintain one question RR key per transaction
Let's simplify things and only maintain a single RR key per transaction
object, instead of a full DnsQuestion. Unicast DNS and LLMNR don't
support multiple questions per packet anway, and Multicast DNS suggests
coalescing questions beyond a single dns query, across the whole system.

78c6a153c4 resolved: rework synthesizing logic
With this change we'll now also generate synthesized RRs for the local
LLMNR hostname (first label of system hostname), the local mDNS hostname
(first label of system hostname suffixed with .local), the "gateway"
hostname and all the reverse PTRs. This hence takes over part of what
nss-myhostname already implemented.

Local hostnames resolve to the set of local IP addresses. Since the
addresses are possibly on different interfaces it is necessary to change
the internal DnsAnswer object to track per-RR interface indexes, and to
change the bus API to always return the interface per-address rather than
per-reply. This change also patches  the existing clients for resolved
accordingly (nss-resolve + systemd-resolve-host).

This also changes the routing logic for queries slightly: we now ensure
that the local hostname is never resolved via LLMNR, thus making it
trustable on the local system.

This moves is_gateway() from nss-myhostname into the basic APIs, and

is_gateway_hostname() to make it more expressive.

Sharing this function in src/basic/ allows us to reuse the function for
routing name requests in resolved (in a later commit).
