Let's do these checks like we try to do them elsewhere, in the
function, not outside. This avoids having to declare the function
arguments twice and keeps the logic for each function together
instead of spread out across the file.
This commit cleans up the includes for all the small tools across
the tree.
A few cases of returning EXIT_SUCCESS are replaced with returning
0 to avoid including <stdlib.h>.
Split out of #37344.
Instead of recalculating the length of the string again after
reading it, let's make sd_netlink_message_read_string() return the
length of the string that we then use to check if the last character
is a dot or not.
This allows us to get rid of the string-util.h include in #37344.
On OBS the build VM is heavily locked down, with network
disabled in various ways in the custom kernel, to isolate the
build, including disabling CONFIG_UNIX_DIAG.

capability_quintet_mangle() can be called with capability sets
containing unknown capabilities. Let's not crash when this is the
case but instead ignore the unknown capabilities.

With 'or', we ignore the empty string (but not '0'), and we only call
time.time() lazily. So this works the same as the code that is replaced,
but avoids the ugly repetition.
We recommend that users create overriddes. This creates the problem that there
is no syntax to unset a property. Thus, the user needs to just set the property
to "something else" in the override file. But then the blurb saying that
"VAR=1" (or "VAR=0" in some cases) is the only allowed value can be confusing.
Say that both 0 and 1 can be set, since this documentation is also intended
for end users.
In our files, we generally don't want the override values anywhere. But we
have a test which checks the rvalue, which should be enough.
We don't want to encourage people to copy the whole files. The
boilerplate text that recommends an override file rather than a
full copy appeared first in 0213a26f65,
but was added in other places in 57bb707d48.
Directly inspired by 951e8cb060, but
the wrong boilerplate was added in other places too.
