db69869f26 sleep-config: fix useless check for swapfile type
Since 0c6f1f4ea4 the check was useless, because the kernel will
ever only write "partition" or "file" there.

OTOH, it is possible that "\\040(deleted)" (escaped " (deleted)")
will be added for removed files. This should not happen, so add
a warning to detect those cases.

c4708f1323 tmpfiles: introduce the concept of unsafe operations
Various operations done by systemd-tmpfiles may only be safely done at
boot (e.g. removal of X lockfiles in /tmp, creation of /run/nologin).
Other operations may be done at any point in time (e.g. setting the
ownership on /{run,var}/log/journal). This distinction is largely
orthogonal to the type of operation.

A new switch --unsafe is added, and operations which should only be
executed during bootup are marked with an exclamation mark in the
configuration files. systemd-tmpfiles.service is modified to use this
switch, and guards are added so it is hard to re-start it by mistake.

If we install a new version of systemd, we actually want to enforce
some changes to tmpfiles configuration immediately. This should now be
possible to do safely, so distribution packages can be modified to
execute the "safe" subset at package installation time.

/run/nologin creation is split out into a separate service, to make it
easy to override.

ef72c1f06e man,units: tmpfiles.d(5) cleanup
Condition for /lib (necessary for split /usr) was missing from the unit.

Some changes which were done in tmpfiles.d(5) were not carried over to
systemd-tmpfiles(1).

Also use markup where possible.

3798fd4c30 bus: allow peeking signatures recusively inside of containers
Previously we invalidated the peeked signature as soon as the caller
would recurse into a container, making stack based handling difficult.
With this change we will keep the peeked signature around until the user
advances to the next field.

b67f541f13 bus: switch kdbus bloom filter over to SipHash (from MurmurHash3)
Let's try to standardize on a single non-cryptographic hash algorithm,
and for that SipHash appears to be the best answer.

With this change there are two other hash functions left in systemd: an
older version of MurmurHash embedded into libudev for the bloom filters
in udev messages (which is hard to update, given that the we probably
should stay compatible with older versions of the library). And lookup3
in the journal files (which we could replace for new files, but which is
probably not worth the work).

09812eb764 sd-daemon: introduce sd_watchdog_enabled() for parsing $WATCHDOG_USEC
Also, introduce a new environment variable named $WATCHDOG_PID which
cotnains the PID of the process that is supposed to send the keep-alive
events. This is similar how $LISTEN_FDS and $LISTEN_PID work together,
and protects against confusing processes further down the process tree
due to inherited environment.
