selinux: fix regression of systemctl subcommands when absolute unit file paths are specified
The commit
4938696301a914ec26bcfc60bb99a1e9624e3789 overlooked the
fact that unit files can be specified as unit file paths, not unit
file names, wrongly passing a unit file path to the 1st argument of
manager_load_unit() that handles it as a unit file name. As a result,
the following 4 systemctl subcommands:
enable
disable
reenable
link
mask
unmask
fail with the following error message:
# systemctl enable /usr/lib/systemd/system/kdump.service
Failed to execute operation: Unit name /usr/lib/systemd/system/kdump.service is not valid.
# systemctl disable /usr/lib/systemd/system/kdump.service

# systemctl unmask /usr/lib/systemd/system/kdump.service
Failed to execute operation: Unit name /usr/lib/systemd/system/kdump.service is not valid.
To fix the issue, first check whether a unit file is passed as a unit
file name or a unit file path, and then pass the unit file to the
appropreate argument of manager_load_unit().
By the way, even with this commit mask and unmask reject unit file
paths as follows and this is a correct behavior:
# systemctl mask /usr/lib/systemd/system/kdump.service
Failed to execute operation: Invalid argument
# systemctl unmask /usr/lib/systemd/system/kdump.service

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.

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.

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.

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 ".".

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.)

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...

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.

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

This new bus call opens an interactive shell in a container. It works

PolicyKit privilege.

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).
