086891e5c1 log: add an "error" parameter to all low-level logging calls and intrdouce log_error_errno() as log calls that take error numbers
This change has two benefits:

- The format string %m will now resolve to the specified error (or to
  errno if the specified error is 0. This allows getting rid of a ton of
  strerror() invocations, a function that is not thread-safe.

- The specified error can be passed to the journal in the ERRNO= field.

Now of course, we just need somebody to convert all cases of this:

        log_error("Something happened: %s", strerror(-r));

into thus:

        log_error_errno(-r, "Something happened: %m");

5f68e74b6a kmod-setup: improve for "kdbus" word on the kernel cmdline
We really shouldn't check for words with "strstr()"...

63cc4c3138 sd-bus: sync with kdbus upstream (ABI break)
kdbus has seen a larger update than expected lately, most notably with
kdbusfs, a file system to expose the kdbus control files:

 * Each time a file system of this type is mounted, a new kdbus
   domain is created.

 * The layout inside each mount point is the same as before, except
   that domains are not hierarchically nested anymore.

 * Domains are therefore also unnamed now.

 * Unmounting a kdbusfs will automatically also detroy the
   associated domain.

 * Hence, the action of creating a kdbus domain is now as
   privileged as mounting a filesystem.

 * This way, we can get around creating dev nodes for everything,
   which is last but not least something that is not limited by
   20-bit minor numbers.

The kdbus specific bits in nspawn have all been dropped now, as nspawn
can rely on the container OS to set up its own kdbus domain, simply by
mounting a new instance.

A new set of mounts has been added to mount things *after* the kernel
modules have been loaded. For now, only kdbus is in this set, which is
invoked with mount_setup_late().

c47fc1f025 kmod: conditionalize kmod setup on CAP_SYS_MODULE, not whether we run in a container
It's generally preferrable to conditionalize on the actual ability to do
something then the context we run in.

b4b879648c kmod-setup: properly iterate through module table
Previously we skipped every second entry.

This also cleans up much of the code and removes some dead code.

3dfb265083 kmod-setup: mounting efivarfs, *after* we tried to mount it, is pointless
The mount() system call, which we issue before loading modules, will trigger
a modprobe by the kernel and block until it returns. Trying to load it again
later, will have exactly the same result as the first time.

f271dd9762 systemd: mount the EFI variable filesystem
Add efivarfs to the mount_table in mount-setup.c, so the EFI variable
filesystem will be mounted when systemd executed.

The EFI variable filesystem will merge in v3.7 or v3.8 linux kernel.

5430f7f2bc relicense to LGPLv2.1 (with exceptions)
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.

Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.

The bits that used to be MIT continue to be MIT.

The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.
