path-util: fix path_is_mount_point() for symlinks
path_is_mount_point() compares the mount_id of a directory and the
mount_id of the parent directory. When following symlinks, the function
to get the parent directory does not take the symlink into account.
/bin -> /usr/bin with /usr being a mountpoint:
mount_id of /bin with AT_SYMLINK_FOLLOW != mount_id of /

bus-proxy: add support for "GetConnectionCredentials" method
GetConnectionCredentials method was added to dbus-1 specification
more than one year ago. This method should return "[...] as many
credentials as possible for the process connected to the server",
but at this moment only "UnixUserID", "LinuxSecurityLabel" and
"ProcessID" are defined by the specification. We should add support
for next credentials after extending dbus-1 spec.

fsckd: clean up log messages
Avoid double logs printing. Not that we don't return
manager_update_global_progress() to the handler callback as if the console or
plymouth isn't available momentarily, we still desire to handle future
fd progress events if those are available again (like cancellation, reports…)
Usually when using loop_read(), we want to read the full buffer.
Add a helper that mirrors loop_write(), and returns 0 when full buffer
was read, and an error otherwise.
Use -ENODATA for the short read, to distinguish it from a read error.

udevd: close race in udev settle
The udev-settle guarantees that udevd is no longer processing any of the
events casued by udev-trigger. The way this works is that it sends a
synchronous PING to udevd after udev-trigger has ran, and when that returns
it knows that udevd has started processing the events from udev-trigger.
udev-settle will then wait for the event queue to empty before returning.
However, there was a race here, as we would only update the /run state at
the beginning of the event loop, before reading out new events and before
processing the ping.
That means that if the first uevent arrived in the same event-loop iteration
as the PING, we would return the ping before updating the queue state in /run
(which would happen on the next iteration).
The race window here is tiny (as the /run state would probably get updated
before udev-settle got a chance to read /run), but still a possibility.
Fix the problem by updating the /run state as the last step before returning
the PING.
We must still update it at the beginning of the loop as well, otherwise we
risk being stuck in poll() with a stale state in /run.

sysusers: do not reject users with already present /etc/shadow entries
This is needed to interoperate firstboot and sysusers. The former one is started
first, and it writes only /etc/shadow when it is told to set the root password.

core: do not spawn jobs or touch other units during coldplugging
Because the order of coldplugging is not defined, we can reference a
not-yet-coldplugged unit and read its state while it has not yet been
set to a meaningful value.
This way, already active units may get started again.
We fix this by deferring such actions until all units have been at
least somehow coldplugged.

vconsole: match on vtcon events, not fbcon ones
I observe that upon loading of framebuffer drivers, I do not get the
desired system font, but the kernel-level defaults (usually
lib/fonts/font_8x16.c, but your mileage may vary depending on kernel
config and boot options).
The fbcon driver may be loaded at a time way before the first
framebuffer device is active, such that the vconsole setup helper
runs too early.
The existing rule is non-fitting. The going live of the fbcon kernel
component does not indicate the proper time at which to load the
visuals, which really ought to be done when a new vtcon object comes
into existence. (The font table is a per-vtcon property.)

login: make hold-off timeout configurable
This introduces 'HoldoffTimeoutSec' to logind.conf to make
IGNORE_LID_SWITCH_{SUSPEND,STARTUP}_USEC configurable.
Background: If an external monitor is connected, or if the system is
docked, we want to ignore LID events. This is required to support setups
where a laptop is used with external peripherals while the LID is closed.
However, this requires us to probe all hot-plugged devices before reacting
to LID events. But with modern buses like USB, the standards do not impose
any timeout on the slots, so we have no chance to know whether a given
slot is used or not. Hence, after resume and startup, we have to wait a
fixed timeout to give the kernel a chance to probe devices. Our timeout
has always been generous enough to support even the slowest devices.
However, a lot of people didn't use these features and wanted to disable
the hold-off timer. Now we provide a knob to do that.
