a6cc569e33 sd-dhcp-client: split sd_dhcp_lease from sd_dhcp_client
This allows us users of the library to keep copies of old leases. This is
used by networkd to know what addresses to drop (if any) when the lease
expires.

In the future this may be used by DNAv4 and sd-dhcp-server.

c3ab23898f networkd: don't check for ifindex in answer to RTM_NEWLINK
The kernel will not be changed to support this, so drop the code. Listening
for all RTM_NEWLINK messages and filtering on name is reliable, so it is not
a problem.

50add2909c networkd: netdev - reduce chance of race when receiving netdev's ifindex
When creating a new link, the kernel will not inform us about the new ifindex
in its ack. We have to listen for newly created devices and deduce the new
ifindex by matching on the ifname.

We used to do this by waiting for a new device from libudev, but that is asking
for trouble, as udev will happily rename the device before handing it to us.
Listen on rtnl instead, the chance of the name being changed before reaching us
is much smaller (if not nil).

Kernel patch in the works to make this unneccessary.

377a218f87 sd-dhcp-client/net-util: make netmask_to_prefixlen generic
This was originally included in the dhcp-client at my request, but it is not
really dhcp-specific and useful outside of it, so let's pull it out.

eb27aeca24 networkd: dhcpv4 - add notion of 'CriticalConnection'
These connections are never torn down, even when the DHCP specifications say that
they should be. This is useful/necessary when the rootfs (or another critical fs)
is mounted over this network connection, and dataloss would result if the connection
is lost.

This option defaults to off, but our initrd generator (TBD) will enable it when
applicable.

b25ef18b33 sd-dhcp-client: refactor client_{free,new}
Make them more simiar to sd_bus and friends. Also factor out the event attachment. In the future,
we will likely want to support external main-loops, so this is a first step. For the time being,
we are still requiring an sd_event to be attached though.

bcbca8291f networkd: don't hard depend on system bus
We may not have a dbus daemon in the initrd (until we can rely on kdbus). In
this case, simply ignore any attempts at using the bus. There is only one user
for now, but surely more to come.

In order to work reliably in the real root without kdbus, but at the same time
don't delay boot when kdbus is in use, order ourselves after dbus.service.

3bef724f7e networkd: generate resolv.conf
This adds support to generate a basic resolv.conf in /run/systemd/network.
This file will not take any effect unless a symlink is created from
/etc/resolv.conf.

Nameservers received over DHCP takes precedence over statically configured ones.

Note: /etc/resolv.conf is severely limited, so in the future we will likely
rather provide a much more powerfull nss plugin (or something to that effect),
but this should allow current users to function without any loss of
functionality.

924fe4304a networkd: bridge - remove redundant state
We will not insist on getting the reply from rtnl that the bridge
was created before considering the bridge ready, as we will be
notified about that via udev. We will listen for the rtnl response
however, in case the creation of the bridge failed.

f46685a4c0 networkd: don't automatically reload config at runtime
We don't know if the config will be consistent, so do as systemd itself and only
load config when the daemon starts (and possibly, in the future, when explicitly requested).

628706137e networkd: print the received DHCPv4 address and gateway
It seems that networkd stores in_addr.s_addr contents in reverse
order (little-endian, not network order). This is a bit confusing,
but sd_rtnl evidently likes this order.

b3070dc025 networkd: refuse to use .network files with missing Address/Gateway key
These keys are mandatory in [Address]/[Route] sections. Otherwise, we
hit an assert:

ens3: setting addresses
Assertion 'address->family == 2 || address->family == 10' failed at /build/amd64-generic/tmp/portage/sys-apps/systemd-9999-r1/work/systemd-9999/src/network/networkd-address.c:137, function address_configure(). Aborting.

Reported-by: Alex Polvi <alex.polvi@coreos.com>

At the same time make sure Route's Destination and Gateway uses the same address family.
