sd-dhcp-client: use asynchronous_close()
close() is a blocking call, which may slow things down measurably when running many dhcp
clients in the same single-threaded main loop. Let's just use the asynchronous version
instead to avoid the problem.
- Also only allow positive ifindex on both dhcp and ipv4ll
[tomegun: the kernel always sets a positive ifindex, but some APIs accept
ifindex=0 with various meanings, so we should protect against
accidentally passing ifindex=0 along.]
job: add waiting jobs to run queue in unit_coldplug
When we have job installed and added to run queue for service which is
still in dead state and systemd initiates reload then after reload we
never add deserialized job to the run queue again. This is caused by
check in service_coldplug() where we check if deserialized state is
something else than dead state, which is not the case thus we never call
service_set_state() and finally unit_notify() where we would have added
job to the run queue.
Thanks to Michal Sekletar <msekleta@redhat.com> for the original patch.

networkd-wait-online: refactor a bit
Clarify that we are waiting for any link to reach 'carrier' state, regardless
of who manages it. This will be useful when we add support for waiting for more
operational states.
udev: warn when name_to_handle_at is not implemented
We have a bunch of reports from people who have a custom kernel and
are confused why udev is not running. Issue a warning on
error. Barring an error in the code, the only error that is possible
is ENOSYS.

udev: increase the size of RESULT buffer
Under some conditions, in udev_rules_apply_to_event the fact that
result is 1024 bytes, creates problems if the output of the running
command/app is bigger then 1024 bytes.

Add more password agent information
Add an (optional) "Id" key in the password agent .ask files. The Id is
supposed to be a simple string in "<subsystem>:<target>" form which
is used to provide more information on what the requested passphrase
is to be used for (which e.g. allows an agent to only react to cryptsetup
requests).

networkd-wait-online: improve interoptability and enable by default
To make sure we don't delay boot on systems where (some) network links are managed by someone else
we don't block if something else has successfully brought up a link.
We will still block until all links we are aware of that are managed by networkd have been
configured, but if no such links exist, and someone else have configured a link sufficiently
that it has a carrier, it may be that the link is ready so we should no longer block.
Note that in all likelyhood the link is not ready (no addresses/routes configured),
so whatever network managment daemon configured it should provide a similar wait-online
service to block network-online.target until it is ready.
The aim is to block as long as we know networking is not fully configured, but no longer. This
will allow systemd-networkd-wait-online.service to be enabled on any system, even if we don't
know whether networkd is the main/only network manager.
Even in the case networking is fully configured by networkd, the default behavior may not be
sufficient: if two links need to be configured, but the first is fully configured before the
second one appears we will assume the network is up. To work around that, we allow specifying
specific devices to wait for before considering the network up.
This unit is enabled by default, just like systemd-networkd, but will only be pulled in if
anyone pulls in network-online.target.

analyze: fix plot with bad y size
systemd-analyze plot > test.svg produces output with all y and height
element attributes equal to zero. This of course causes the resulting
svg to appear blank (zero height). Bug does not affect x86. Looks like
a compiler optimization may be the culprit.
