Since the backing ioctl for this on kdbus is the same we retain
atomicity this way.

This way we can unify handling of credentials that are attached to
messages, or can be queried for bus name owners or connection peers.
This also adds the ability to extend incomplete credential information
with data from /proc,
Also, provide a convenience call that will automatically determine the
most appropriate credential object for an incoming message, by using the
the attached information if possible, the sending name information if
available and otherwise the peer's credentials.

when not active
This way, we can avoid executing two /bin/swapon jobs to be dispatched
for the same swap device if it is configured for two different paths.
Previously we were just tracking the device nodes of active swap
devices, which would not allow us to recognize the identity of two swap
devices before they are active.

to deal with shells
This makes shutdown a bit faster if debug-shell.service is enabled.

Pass on the line on which a section was decleared to the parsers, so they
can distinguish between multiple sections (if they chose to). Currently
no parsers take advantage of this, but a follow-up patch will do that
to distinguish
[Address]
Address=192.168.0.1/24
Label=one
[Address]
Address=192.168.0.2/24
Label=two
from

Address=192.168.0.1/24

We expect the event on /proc/swaps before we expect the SIGCHILD,
reflect this in the state machine.

Always read all external events before we decide what we do next.

All calls that set a sd_bus_error structure will now return the same
error converted to a negative errno. This may be used as syntactic sugar
to return from a function and setting a bus_error structure in one go.
Also, translate all Linux Exyz (EIO, EINVAL, EUCLEAN, EPIPE, ...)
automatically into counterparts in the (new) "Posix.Error." namespace.
If we fail to allocate memory for the components of a sd_bus_error
automatically reset it to an OOM error which we always can write.

Just in order to bring things inline with the method and property
callbacks.

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.

Since valgrind only generates useful output on exit() (rather than
exec()) we need to explicitly exit when valgrind is detected.
