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
path prefix is used.
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
installers like Anaconda which unconditionally populate /etc/fstab to
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
API. However, it's mostly an implementation detail for now, hence move
it out of the stable block device dir.

logind: add a debug message in case the session already exists
If the session already exists then the only way to log it is to set the
debug option of pam_systemd. There are no debug messages in the login
service that permits to log if the session already exists.
So just add it, and while we are it add the "uid" field to the debug
message that indicates that the session was created.

systemctl: for switch-root check, if we switch to a systemd init
If "systemctl switch-root" is called with a specific "INIT" or
/proc/cmdline contains "init=", then systemd would not serialize
itsself.
Let systemctl check, if the new init is in the standard systemd
installation path and if so, clear the INIT parameter,
to let systemd serialize itsself.

process the Disconnected message yet, don't generate multiple warning

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.

rules: mark loop device as SYSTEMD_READY=0 if no file is attached
Check existence of loop/backing_file in sysfs and mark loop devices with
SYSTEMD_READY if missing. Such loop files is uninitialized and it's not
ready for use yet (there's no file attached).
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
buttons, but axes like RX, THROTTLE, or RUDDER. These don't interfere with
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.

manager: flush memory stream before using the buffer
When the manager receives a SIGUSR2 signal, it opens a memory stream
with open_memstream(), uses the returned file handle for logging, and
dumps the logged content with log_dump().
However, the char* buffer is only safe to use after the file handle has
been flushed with fflush, as the man pages states:
When the stream is closed (fclose(3)) or flushed (fflush(3)), the
locations pointed to by ptr and sizeloc are updated to contain,
respectively, a pointer to the buffer and the current size of the
buffer.
These values remain valid only as long as the caller performs no
further output on the stream. If further output is performed, then the
stream must again be flushed before trying to access these variables.
Without that call, dump remains NULL and the daemon crashes in
log_dump().

gpt-auto-generator: automatically find the root disk of the system
When run in an initrd and no root= argument is set (or is set to

same disk the EFI ESP is located on.
Since we look for swap, /home and /srv on the disk the root partition is
located on, we hence have a fully discoverable chain:
Firmware discovers the EFI ESP partition → the initrd discovers the
root partition → the host OS discovers swap, /home, and /srv.
Note that this requires an EFI boot loader that sets the
LoaderDevicePartUUID EFI variable, such as Gummiboot.
