Given that plymouth listens on an abstract namespace socket and if
CLONE_NEWNET is not used the abstract namespace is shared with the host
we might actually end up send plymouth data to the host.
This patch converts PID 1 to libsystemd-bus and thus drops the
dependency on libdbus. The only remaining code using libdbus is a test
case that validates our bus marshalling against libdbus' marshalling,
and this dependency can be turned off.
This patch also adds a couple of things to libsystem-bus, that are
necessary to make the port work:
- Synthesizing of "Disconnected" messages when bus connections are
severed.
- Support for attaching multiple vtables for the same interface on the
same path.
This patch also fixes the SetDefaultTarget() and GetDefaultTarget() bus
calls which used an inappropriate signature.
As a side effect we will now generate PropertiesChanged messages which
carry property contents, rather than just invalidation information.
When a service exits succesfully and has RemainAfterExit set, its hold
on the console (in m->n_on_console) wasn't released since the unit state
didn't change.
Since 31a7eb86 the output on console can be disabled to avoid colliding with
gettys. However, it could also lead to a lack of messages during
shutdown/reboot.

reboot syscall can be performed with an additional argument. In some
systems this functionality can be useful to modify the mode of the
next boot performed by the bootloader.
Instead of individually checking for containers in each user do this
once in a new call proc_cmdline() that read the file only if we are not
in a container.
This way cleaning up the cgroup tree on shutdown is a lot easier since
we are in the root dir. Also PID 1 was previously artificially placed in
system.slice, even though our rule actually was not to have processes in
slices. The root slice otoh is magic anyway, so having PID 1 in there
sounds less surprising.
Of course, this means that PID is scheduled against the three top-level
slices.

-Og Optimize debugging experience. -Og enables optimizations that do
not interfere with debugging. It should be the optimization level of
choice for the standard edit-compile-debug cycle, offering a
reasonable level of optimization while maintaining fast compilation
and a good debugging experience.
We now treat passno as boleans in the generators, and don't need this any more. fsck itself
is able to sequentialize checks on the same local media, so in the common case the ordering
is redundant.
It is still possible to force an order by using .d fragments, in case that is desired.
The code was actually safe, because b should
never be null, because if rvalue is empty, a different
branch is taken. But we *do* check for NULL in the
loop above, so it's better to also check here for symmetry.
If the function failed, nothing serious would happen
because unlink would probably return EFAULT, but this
would obscure the real error and is a bit sloppy.
This extends 62678ded 'efi: never call qsort on potentially
NULL arrays' to all other places where qsort is used and it
is not obvious that the count is non-zero.
