This change checks¹ if the system does not have a br0 interface, creates
a default one consisting of all switch ports in VLAN 1 of br0.
On top of br0 a vlan1 management interface is created with DHCP address.
For emulation and test purposes, a way to supply tap interfaces from
Qemu, and pass off as if they were regular switch ports, is added.
____
¹ obviously a better way to detect a factory-reset device is needed,
not all systems running infix will need or want a br0 interface.

The qemu.sh script can fail, due to misconfiguration or other problems,
before it actually starts qemu. Therefore, move the help text to right
before starting the emulator.

The virtualized system is configured through kconfig under "External
Options"->"QEMU Virtualization".
To launch the system, simply run "make run". This works both from
output directories, and from the infix root with O= set.
