test-network: make wait_online() check setup state
Previously, event if link's setup state is in failed, tests may pass,
as systemd-networkd-wait-online success if the state is in failed state.
This makes tests be checked more strictly.
network: make link enter failed state when a configuration fails
Some path of configuring address, route or etc., go to failed state, but
some do not. E.g., failure in address configuration which is provided by
DHCPv4 goes to failed state, but static address does not.
This is just for consistency. This should not change anything if
everything is fine.

systemctl: do not suggest passing --all if the user passed --state=
"systemctl --failed" suggested I pass "--all" to see units in the inactive
state as well. I thought this was not very useful. If you explicitly
asked for units in a specific state, then you already know you have
narrowed it down. And if you ran "systemctl --state=inactive", it is even
more strange to see this message.
@keszybz suggests we probably don't want to suggest "list-unit-files"
either :-). Let's only suggest that if the user passed "--state=inactive".
Finally, this means the output for "systemctl --failed" could be just
"0 loaded units listed". In this case, we don't need any highlight on that
text, to distinguish it from the hint. This matches "list-unit-files".
This also means we happen to avoid using red highlight, when there are zero
failed units, as if that itself was a failure. @kesbyz pointed out that
old behaviour was a bit weird.

man: offline-updates: make dependence on system-update.target explicit
Current operation of system-update-cleanup.service (removing /system-update
symlink and rebooting) implies that any update must complete *before*
system-update.target is reached.
Update recommendations to include explicitly setting
Before=system-update.target in services that use offline-updates mode.

locale-util: suppress non-UTF-8 locales when enumerating them
Let's hide non-UTF-8 locales by default. It's 2019 after all.
Let's add an undocumented env var to reenable listing them though.
This should substantially shorten the list of choices we offer users,
and only show realistic choices.
note that only firstboot and localectl make use of this information, and
both allow configuration of values outside of these lists, hence all
this change does is hide legacy options, but they are still available if
you know what you do, and that's how it should be.
network: do not change to configuring state needlessly
When DHCP or any other dynamic addresses are changed, then
link_request_set_routes() is invoked, and even if no static routes
are configured, the operational state is needlessly changed to
configuring state.
This makes the state is changed only when static routes are configured.
Let's remove some unnecessary confusion around signed/unsigned types for
log levels. Let's just stick to signed, because that is what glibc
generally appears to use.
While we are at it, add explicit logging for all error causes.
util-lib: [static] array argument sizes are apparently not OK for NULL parameters
Let's drop the 'static' logic when a parameter can be NULL.
I think asan/ubsan are right here, judging by the C99 spec language:
"A declaration of a parameter as ‘‘array of type’’ shall be adjusted to
‘‘qualified pointer to type’’, where the type qualifiers (if any) are
those specified within the [ and ] of the array type derivation. If the
keyword static also appears within the [ and ] of the array type
derivation, then for each call to the function, the value of the
corresponding actual argument shall provide access to the first element
of an array with at least as many elements as specified by the size
expression."
If we specify NULL, then we certainly don't pvode access to any valid
array.
Coverity was complaining that read() does not terminate the data. But
we did that termination earlier, so covirity is wrong (CID#1402306, CID#1402340).
Let's modernize the style a bit nevertheless.
(size_t) cast is needed to avoid the warning about comparison, iff
the value is not a constant.
shared: add generic logic for waiting for a unit to enter some state
This is a generic implementation of a client-side logic of waiting until
a unit enters or leaves some state.
This is a more generic implementation of the WaitContext logic currently
in systemctl.c, and is supposed to replace it (a later commit does
this). It's similar to bus-wait-for-jobs.c and we probably should fold
that one into it later on.
This code is more powerful and cleaner than the WaitContext logic
however. In addition to waiting for a unit to exit this also allows us
to wait for a unit to leave the "maintainance" state.
This commit only implements the generic logic, and adds no users of it
yet.
