The new network parser will support specifying multiple networks in the old
format where each new non-indexed "lxc.network.type" line starts a new network
configuration. This way we don't break users. For now, we just print a
deprecation warning. We will KILL this in LXC 3.0.

Some of the checks were previously performed when parsing the network config.
But since we allow for a little more flexibility now it doesn't work anymore.
Instead, let's validate the network at creation time.

lxc_get_netdev_by_idx() takes care of checking whether a given netdev struct
for a given index is already allocated. If so it returns a pointer to it to the
caller.
If it doesn't find it it will allocate a new netdev struct and insert it into
the network list at the right position. For example, let's say you have the
following networks defined in your config file:

lxc.network.0.type=veth
lxc.network.0.link=lxcbr0
lxc.network.0.name=eth0
lxc.network.0.flags=up

lxc.network.3.type=veth
lxc.network.3.link=lxcbr0
lxc.network.3.name=eth1
lxc.network.3.flags=up
lxc.network.3.hwaddr = 00:16:3e:5d:7d:65

lxc.network.1.type=veth
lxc.network.1.link=lxcbr0
lxc.network.1.name=eth0
lxc.network.1.flags=up

lxc_get_netdev_by_idx() will take care that the internal network list appears
in the order:

0
1
3

The ordering of the keys themselves can also be random, meaning you could do:

lxc.network.3.type=veth
lxc.network.0.link=lxcbr0
lxc.network.0.name=eth0
lxc.network.3.hwaddr = 00:16:3e:5d:7d:65
lxc.network.0.flags=up
lxc.network.3.flags=up
lxc.network.0.type=veth
lxc.network.3.link=lxcbr0
lxc.network.3.name=eth1

and lxc_get_netdev_by_idx() would still figure out the correct ordering since
it keeps track of the index.

tree-wide: priority -> level

When we merged the new logging function for the api we exposed the log level
argument in the struct as "priority" which we actually requested to be changed
to "level" which somehow didn't happen and we missed it. Given the fact there
has been no new liblxc release let's fix it right now before it hits users.
Also, take the chance to change the terminology in the log from "priority" to
"level" globally. This is to prevent confusion with syslog's "priority"
argument which we also support.

start: kill lxc-monitord

Since we kicked lxc-monitord there will very likely be no user processes around
anymore after all container's have been stopped. Which is a very very very good
thing. So let's not error out when pkill doesn't find any processes.
