lxc-update-config: handle legacy networks

Older instances of liblxc allowed to specify networks like this:

lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = lxdbr0
lxc.network.name= eth0

lxc.network.type = veth
lxc.network.flags = up
lxc.network.link = lxdbr0
lxc.network.name = eth1

Each occurrence of "lxc.network.type" indicated the definition of a new
network. This syntax is not allowed in newer liblxc instances. Instead, network
must carry an index. So in new liblxc these two networks would be translated to:

lxc.net.0.type = veth
lxc.net.0.flags = up
lxc.net.0.link = lxdbr0
lxc.net.0.name= eth0

lxc.net.1.type = veth
lxc.net.1.flags = up
lxc.net.1.link = lxdbr0
lxc.net.1.name = eth1

The update script did not handle this case correctly. It should now.

So far, when creating veth devices attached to openvswitch bridges we used to
fork() off a thread on container startup. This thread was kept around until the
container shut down. I have no good explanation why we did it that why but it's
certainly not necessary. Instead, let's fork() off the thread on container
shutdown to delete the veth.

"lxc.cgroup.dir" can be used to set the name of the directory the container's
cgroup will be created in. For example, setting

    lxc.uts.name = c1
    lxc.cgroup.dir = lxd

would make liblxc create the cgroup

    lxd/c1

Use deb.debian.org as the default Debian mirror

The httpredir.debian.org service has been discontinued in favour of
deb.debian.org and httpredir.debian.org now redirects to deb.debian.org.

Surfaced while building lxc-2.0.8 on e2k architecture with lcc,
looks like its -Wall is more pedantic than gcc's:

lcc: "conf.c", line 1514: error: unrecognized character escape sequence
          [-Werror]
        DEBUG("created directory for console and tty devices at \%s\"", path);
                                                                ^
 in expansion of macro "DEBUG" at line 1514

Another byte is a leading whitespace fix while at that.
