We need to properly initialize all error structs before use and free
them after use.
Also, there's no point in flushing stdout if we output a \n anyway...

Use [brackets] only for optional elements.
Use <optional> in XML sources.

wait_for_jobs was ignoring the errors from the jobs stored in r.
It would only ever return whether the call to sd_bus_remove_filter
went ok. This patch changes it to return the first job related error
encountered. If a job related error is found, then the result of the
call to sd_bus_remove_filter is ignored.
wait_for_jobs was a bit hard to read so I split it up to avoid
the goto and deep nesting.

It is nicer to say 'systemctl list-units ssh\*' then to use grep,
because colouring is preserved and it is easier to match just against
the unit name.

The only problem is that libgen.h #defines basename to point to it's
own broken implementation instead of the GNU one. This can be fixed
by #undefining basename.

- Add space between if/for and the opening parentheses
- Place the opening brace on same line as the function (not for udev)
From the CODING_STYLE
Try to use this:
void foo() {
}
instead of this:
void foo()
{
}

Those files can be in a completely deferent format and also
arbitrarily long, and usually contain information about other
stuff. If we ever add SourceLine= or SourceLines= in addition
to SourcePath=, and can show the relevant information only, this
commit can be reverted.

Also, expose the new "flush" job mode this way.

Message handler callbacks can be simplified drastically if the
dispatcher automatically replies to method calls if errors are returned.
Thus: add an sd_bus_error argument to all message handlers. When we
dispatch a message handler and it returns negative or a set sd_bus_error
we send this as message error back to the client. This means errors
returned by handlers by default are given back to clients instead of
rippling all the way up to the event loop, which is desirable to make
things robust.
As a side-effect we can now easily turn the SELinux checks into normal
function calls, since the method call dispatcher will generate the right
error replies automatically now.
Also, make sure we always pass the error structure to all property and
method handlers as last argument to follow the usual style of passing
variables for return values as last argument.

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.

The call is one of the most important ones we expose, where we place
major emphasis on. We should make sure to give it a short, memorable
name.

Also change sd_bus_message_exit_container to return -ENOENT
when not in a container, to make it easier to distinguish different
errors.

do the same for list-jobs

Otherwise 'not-found' overflows into the ACTIVE column.

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.

Among other things this makes sure we always expose a --version command
and show it in the help texts.

We can determine the list entry type via the typeof() gcc construct, and
so we should to make the macros much shorter to use.

Since the invention of read-only memory, write-only memory has been
considered deprecated. Where appropriate, either make use of the
value, or avoid writing it, to make it clear that it is not used.
