Instead of orange0phys we should use orangephys0 this patch implements
the necessary changes.

This bridge mode is supposed to be used for virtual environments
to create a network zone as a bridge and have virtual machines inside
it. Other physical interfaces can also be added to the bridge.
This is very similar to the MACVTAP bridge feature but still works
when the link of any (or all) physical interfaces is down.

This change make it possible to use a macvtap interface as a
standard interface (green0).
This is required by libvirt, because libvirt adds macvtap interfaces to
the physical interface, but this causes a problem. A VM with this
configuration can communicate with the whole network,
but not with the Host (IPFire).
To solve this problem, the host interface must be also a macvtap interface.
This is achieved by:
1. In /var/ipfire/ethernet/settings the mode of a interface could set
with GREEN_MODE= ...
When the mode is macvtap the physical interface is renamed to green0phys
instead of green0. If the mode is not set the normal configuration is
applied .
2. The network-hotplug-macvtap script checks if a physical nic ends
with "phys".
When the interface ends with "phys", the script adds a macvtap interface
to the physical nic which is named green0. The MAC address of this
interface is set to the MAC address of the physical nic. The MAC address
of the physical is set to a random value. We do this because the MAC
address of green0 should not change.
All services, IP addresses then binds to the macvatap interface, the
physical nic is not used.
PS.: The script works also with the orange or blue interface, just
replace green with orange or blue.

Instead of creating a copy of the configuration values and
for better extensibility, we will have udev execute a script
that parses /var/ipfire/ethernet/settings and will return the
correct name of the corresponding device (green0, blue0, ...).
