sd-bus: don't look for a 64bit value when we only have 32bit value on reply cookie hash table access
This broke hashtable lookups for the message cookies on s390x, which is
a 64bit BE machine where accessing 32bit values as 64bit and vice versa
will explode.
Also, while we are at it, be a bit more careful when dealing with the
64bit cookies we expose and the 32bit serial numbers dbus uses in its
payload.

nspawn: make host0's MAC address persistent
We still need to make sure that no two MAC addresses are the same, so we use
a logic similar to what is used in udev to generate MAC addresses, and base
it on a hash of the host's machine ID and thecontainer's name.
getty: Start getty on 3270 terminals available on Linux on System z
Add the first 3270 terminal device that is associated with the Linux preferred
console to the list of virtualization consoles. This is required to
automatically start a getty if the conmode=3270 kernel parameter is specified
for Linux on z/VM instances. Note that a queued upstream patch also enable
the 3270 terminal device if it is associated with the Linux preferred console.
How
To successfully start agetty on a 3270 terminal, a change in the agetty
parameter order is required. Previously, agetty would started like this:
/sbin/agetty --keep-baud 3270/tty1 115200,38400,9600 TERM
The agetty program interprets the "3270/tty1" as baud rate and fails to start
with the "bad speed: 3270/tty1" error message. Fixing this in agetty is more
complex rather than reordering the command line parameters like this:
/sbin/agetty --keep-baud 115200,38400,9600 3270/tty1 TERM
According to agetty sources and "agetty --help", agetty accepts the "tty",
"baudrate tty", and "tty baudrate" specifications.
P.S. The "tty: Set correct tty name in 'active' sysfs attribute" introduces
a change to display the terminal device which is associated with the
Linux preferred console. This change helps to let systemd handle this
particular case only. Without the changes of this commit, no additional
3270 terminal device can be managed by systemd.
gpt-auto-generator: honour read-only and no-auto flag from GPT data

"systemctl list-machines" shows one line per local container which
includes the current system state of the container, the number of failed
units as well as the number of currently queued jobs.
The system state knows the states starting →
running/degraded/maintenance → stopping, where:
starting = system startup
running = normal operation
degraded = at least one unit is currently in failed state
maintenance = rescue/emergency mode is active or queued
stopping = system shutdown

backlight: Avoid restoring brightness to an unreadably dim level
Some systems turn the backlight all the way off at the lowest levels.
Clamp saved brightness to at least 1 or 5% of max_brightness. This

bus: replace sd_bus_label_{escape,unescape}() by new sd_bus_path_{encode,decode}()
The new calls work similarly, but enforce a that a common, fixed bus

This follows discussions with Simon McVittie on IRC that it should be a
good idea to make sure that people don't use the escaping applied here
too wildly as anything other than the last label of a bus path.
fstab-generator: when running in a container, ignore fstab entries referring to device nodes
Since these device nodes will never appear in the container anyway
there's no point in waiting for them.
This makes it easier to boot images generated with general purpose

boot in containers.
gpt-auto-generator: rename root device node symlink to /dev/gpt-auto-root
Before it was placed in /dev/disk/by-id, which makes it a bit too much

it out of the stable block device dir.

nspawn: when resoliving UIDs/GIDs for "-u", do so in forked off /usr/bin/getent instead of in-process
When the container runs a different native architecture than the host we
shouldn't attempt to load the container's NSS modules with the host's
libc. Instead, resolve UID/GID by invoking /usr/bin/getent in the
container. The tool should be fairly universally available and allows us
to do resolving of the UID/GID with the container's libc in a parsable
format.

Check existence of loop/backing_file in sysfs and mark loop devices with

nspawn: don't try mknod() of /dev/console with the correct major/minor
We overmount /dev/console with an external pty anyway, hence there's no
point in using the real major/minor when we create the node to
overmount. Instead, use the one of /dev/null now.
This fixes a race against the cgroup device controller setup we are
using. In case /dev/console was create before the cgroup policy was
applied all was good, but if created in the opposite order the mknod()
would fail, since creating /dev/console is not allowed by it. Creating
/dev/null instances is however permitted, and hence use it.

input_id: Recognize buttonless joystick types
Input devices like rudders or pedals are joystick-like; they don't have

other device types with absolute axes (touch screens, touchpads, and
accelerometers), so it's fairly safe to mark them as ID_INPUT_JOYSTICK and thus
hand out dynamic ACLs to the user.
