4df3277881 modules-load: fix memory leak
=================================================================
==64281==ERROR: LeakSanitizer: detected memory leaks

Direct leak of 32 byte(s) in 1 object(s) allocated from:
    #0 0x7f623c961c4a in malloc (/usr/lib64/libasan.so.2+0x96c4a)

SUMMARY: AddressSanitizer: 32 byte(s) leaked in 1 allocation(s).

This happens due to the wrong cleanup attribute is used (free vs strv_free)

This avoids updating the flag files twice for every loop, and also removes another dependency
in the main-loop, so we are freer to reshufle it as we want.

a8389097c0 udevd: explicitly read out uevents we create ourselves
Rather than skippling ctrl handling whenever we have handlede inotify events
(and hence may have synthesized a 'change' event), just call the uevent
handling explicitly from on_inotify() so that the event queue is up-to-date.

b2c23da8ce core: rename SystemdRunningAs to ManagerRunningAs
It's primarily just a property of the Manager object after all, and we

8b4305c735 unit: move unit_warn_if_dir_nonempty() and friend to unit.c
The call is only used by the mount and automount unit types, but that's
already enough to consider it generic unit functionality, hence move it
out of mount.c and into unit.c.

f2341e0a87 core,network: major per-object logging rework
This changes log_unit_info() (and friends) to take a real Unit* object
insted of just a unit name as parameter. The call will now prefix all
logged messages with the unit name, thus allowing the unit name to be
dropped from the various passed romat strings, simplifying invocations
drastically, and unifying log output across messages. Also, UNIT= vs.
USER_UNIT= is now derived from the Manager object attached to the Unit
object, instead of getpid(). This has the benefit of correcting the
field for --test runs.

Also contains a couple of other logging improvements:

- Drops a couple of strerror() invocations in favour of using %m.

- Not only .mount units now warn if a symlinks exist for the mount
  point already, .automount units do that too, now.

- A few invocations of log_struct() that didn't actually pass any
  additional structured data have been replaced by simpler invocations
  of log_unit_info() and friends.

- For structured data a new LOG_UNIT_MESSAGE() macro has been added,
  that works like LOG_MESSAGE() but prefixes the message with the unit
  name. Similar, there's now LOG_LINK_MESSAGE() and
  LOG_NETDEV_MESSAGE().

- For structured data new LOG_UNIT_ID(), LOG_LINK_INTERFACE(),
  LOG_NETDEV_INTERFACE() macros have been added that generate the
  necessary per object fields. The old log_unit_struct() call has been
  removed in favour of these new macros used in raw log_struct()
  invocations. In addition to removing one more function call this
  allows generated structured log messages that contain two object
  fields, as necessary for example for network interfaces that are
  joined into another network interface, and whose messages shall be
  indexed by both.

- The LOG_ERRNO() macro has been removed, in favour of
  log_struct_errno(). The latter has the benefit of ensuring that %m in
  format strings is properly resolved to the specified error number.

- A number of logging messages have been converted to use
  log_unit_info() instead of log_info()

- The client code in sysv-generator no longer #includes core code from
  src/core/.

- log_unit_full_errno() has been removed, log_unit_full() instead takes
  an errno now, too.

- log_unit_info(), log_link_info(), log_netdev_info() and friends, now
  avoid double evaluation of their parameters

d3650f0c4b units: order nspawn containers after network.target
This way we know that any bridges and other user-created network devices
are in place, and can be properly added to the container.

In the long run this should be dropped, and replaced by direct calls
inside nspawn that cause the devices to be created when necessary.

4dda4e637e Generate systemd-fsck-root.service in the initramfs
In the initrafms, generate a systemd-fsck-root.service to replace
systemd-fsck@<sysroot-device>.service. This way, after we transition
to the real root, systemd-fsck-root.service is marked as already done.

This introduces an unnecessary synchronization point, because
systemd-fsck@* is ordered after systemd-fsck-root also in the
initramfs. In practice this shouldn't be a problem.

c6aa11f200 udevd: worker - drop reference counting
Make the worker context have the same life-span as the worker process. It is created on fork()
and free'd on SIGCHLD.

The change means that we can get worker_returned() for a worker context that is no longer around,
this is not a problem and we can just drop the message. The only use for worker_returned() is to
know to reschedule events to workers that are still around, so if the worker has already exited
it is not important to keep track of. We still print a debug statement in this case to be on the
safe side.
