[Battlemesh-test] First commit

[p4u]

Hi.
I have created a repository in my git account but I would like to 
transfer it to the battlemesh one, however I have not enough rights.

https://github.com/p4u/battlemesh-packages

If you take a quick look in the repository you will see it is an 
openwrt feed (take a look in HOWTO).
So it can be added from any openwrt buildroot.

I created a package named "wbm-testbed" which includes a Makefile with 
some dependencies and a files directory with
some (very few for the moment) data.

There is a config file placed on /etc/config/wbm which contains some 
options, for instance the IP ranges used for the node.

There is a small library in /etc/wbm/lib/ which contains some useful 
functions, for instance to access UCI.
I think we should try to avoid the direct calls to the commands such 
as: uci get network.ifname
We should use an abstraction layer such as: wbm_uci_get network.ifname
So the library must be increased with more functions.

In /etc/wbm/protos there will be a script file for each protocol, for 
instance "batadv.sh" which will configure Batman-adv in
the system according to the options passed by parameter, such as:

protos/batadv.sh dev=wlan0 dev=eth0 ipv6=fdfe:0000:0001:EEFF::/64

I think we should use IPv6 as first option and later on if somebody 
wants to add a legacy support for IPv4, he is welcome.
For IPv6 we can use VLAN tags as explained here 
http://battlemesh.org/BattleMeshV6/Firmware
Link local addresses to communicate the directly connected neighbors 
(to let protocols discover each others).
And ULA IPv6 ranges to reach the routed mesh nodes.

FEEL FREE TO ADD/MODIFY WHATEVER

Cheers
