LXC version 3 config files are still using network old style definition.
So, as LXC supports it now, they can be converted to use this new

Domain definition is useless now inside network structure. This pointer
was required because new network definition was being added each time
that a new network type appeared. So, this should be processed into
old function `lxcNetworkParseDataType()`. Now, as it was moved to an
array, it can be handle together each interface pointer.

Struct lxcNetworkParseData is being used as a single pointer which
iterates through LXC config lines. It means that it will be applied as a
network each time that a new type appears. After, the same struct is
used to populate a new network interface. This commit changes this logic
to multiple lxcNetworkParseData to move this strcuture to an array. It
makes more sense if we are using indexes to fill interface settings.
This is better to improve code clarity.

The rewrite to use GLib's atomic ops functions changed the behavior
of virAtomicIntInc - before it returned the pre-increment value.

Most of the callers using its value were adjusted, but the one
in qemuDriverAllocateID was not. If libvirtd would reconnect to
a running domain during startup, the next started domain would get
the same ID:

$ virsh list
 Id   Name       State
--------------------------
 1    f28live    running
 1    f28live1   running

Use the g_atomic_add function directly (as recommended in viratomic.h)
and add 1 to the result.

This also restores the usual numbering from 1 instead of 0.
