test: bump the timeout for systemd-hwdb-update.service under ASan
Since the hwdb update from
a79be2f80777eb80e0d8177f6bccd7615de7ec1a
the systemd-hwdb-update service started timing out under ASan when
compiled with gcc, as we started tripping over the 3 minutes timeout.
This affects only gcc runs, since the current gcc on Arch still suffers
from the detect_stack_use_after_return performance penalty[0]. Until
the fixed gcc is present in the respective repositories, let's bump
the timeout to 4 minutes, as we might not be able to upgrade right
away, due to systemd/systemd#16199.

file header anyway. This should make our hash tables more robust against
collision attacks, as long as the attacker has no read access to the
journal files. We switch from jenkins to siphash simply because it's
more well-known and we standardize for the rest of our codebase onto it.

that can forge log messages but have no read access to the logs. It has
no effect on clients that have read access.

ci: bring back Coverity part 2
It's just a follow-up to https://github.com/systemd/systemd/pull/16266.
Currently the Coverity stage is failing with

Looks like DOCKER_EXEC got lost somewhere along the way, which, in
turn, caused the "coverity" job to fail with
```

log: introduce log_parse_environment_cli() and log_setup_cli()
Presently, CLI utilities such as systemctl will check whether they have a tty
attached or not to decide whether to parse /proc/cmdline or EFI variable
SystemdOptions looking for systemd.log_* entries.
But this check will be misleading if these tools are being launched by a
daemon, such as a monitoring daemon or automation service that runs in
background.
Make log handling of CLI tools uniform by never checking /proc/cmdline or EFI
variables to determine the logging level.
Furthermore, introduce a new log_setup_cli() shortcut to set up common options
used by most command-line utilities.

networkd: take ref immediately after storing item in set
I'm not sure if I understand the code correctly, but it seems that if
storig in the second set failed, we'd return with the first set having
no reference on the link object, and the link object could be freed in the
future, leaving the set with a dangling reference.

On error, we'd just free the object, and not close the fd.
While at it, let's use set_ensure_consume() to make sure we don't leak

can be achieved.

basic/set: add set_ensure_consume()
This combines set_ensure_allocated() with set_consume(). The cool thing is that
because we know the hash ops, we can correctly free the item if appropriate.
Similarly to set_consume(), the goal is to simplify handling of the case where
the item needs to be freed on error and if already present in the set.
