- Considerably more powerful error returning APIs in libsystemd-bus
- Adapter for connecting an sd_bus to an sd_event
- As I reworked the PolicyKit logic to the new library I also made it
asynchronous, so that PolicyKit requests of one user cannot block out
another user anymore.

The specified time of timer event sources hence becomes the time the
handler is called the *earliest*, and the specified time plus the accuracy
the time by which it is called the *latest*, leaving the library the
freedom to schedule the wake-up somewhere inbetween.
If the accuracy is specified as 0 the default of 250ms will be used.
When scheduling timeouts we will now try to elapse them at the same
point within each second, across the entire system. We do this by using
a fixed perturbation value keyed off the boot id. If this point within a
second is not in the acceptable range, we try again with a fixed time
within each 250ms time step. If that doesn't work either, we wake up at

We use VTNR, not VTNr as key. Until now sd_session_get_vt() just returns
an error.

login: fix invalid free() in sd_session_get_vt()
We need to clear variables markes as _cleanup_free_. Otherwise, our
error-paths might corrupt random memory.

bus: add minimal event loop API
So far we tried to use epoll directly wherever we needed an event loop.
However, that has various shortcomings, such as the inability to handle
larger amounts of timers (since each timerfd costs one fd, which is a
very limited resource, usually bounded to 1024), and inability to do
priorisation between multiple queued events.
Let's add a minimal event loop API around epoll that is suitable for
implementation of our own daemons and maybe one day can become public
API for those who desire it.
This loop is part of libsystemd-bus, but may be used independently of
it.

journald: remove rotated file from hashmap when rotation fails
Before, when the user journal file was rotated, journal_file_rotate
could close the old file and fail to open the new file. In that
case, we would leave the old (deallocated) file in the hashmap.
On subsequent accesses, we could retrieve this stale entry, leading
to a segfault.
When journal_file_rotate fails with the file pointer set to 0,
old file is certainly gone, and cannot be used anymore.

Smack: Test if smack is enabled before mounting
Since on most systems with xattr systemd will compile with Smack
support enabled, we still attempt to mount various fs's with
Smack-only options.
Before mounting any of these Smack-related filesystems with
Smack specific mount options, check if Smack is functionally
active on the running kernel.
If Smack is really enabled in the kernel, all these Smack mounts
are now *fatal*, as they should be.
We no longer mount smackfs if systemd was compiled without
Smack support. This makes it easier to make smackfs mount
failures a critical error when Smack is enabled.
We no longer mount these filesystems with their Smack specific
options inside containers. There these filesystems will be
mounted with there non-mount smack options for now.
