Makes the nodes advertise using DHCP Options 121 and 249 routes to the mesh (10.0.0.0/8) and the reserved (172.16.0.0/12) address ranges.
This change allows directing systems to prefer the mesh node for mesh ranges unless another network rule is more specific (such as a directly connected network)
This is mostly useful where a PC may have multiple network connections active as it improves the desire for the packets to travel via the mesh network.
Currently the:
10.0.0.0/8 range is used by mesh nodes and dtdlinking of mesh nodes.
172.27.0.0/16 is used for default LAN network on NAT nodes.
172.33.0.0/16 is for ad-hoc tunnels
All others in the advertised range are reserved for future network use.
nvram-setup may be the only script we have to worry about as it may call configs for interfaces that do not exist in the current mode.
By default get_interface will return a static mapping when it can't find an active config entry meaning that eventually get_interface will need an update routine to pull out of local running config
The lack of this update routine should be acceptable for now as we have no GUI for users to change the mapping.
Create get_interface which will lookup in the current uci network config the realname for the logical interface name.
When the interface is not found it will fall back to a hard coded list.
Configure the UI to use the new get_interface function.
Under Barrier Breaker sometimes OLSRD gets started before any interface is up causing OLSRD to shutdown because no interfaces exist.
Forces OLSRD to stay on and wait for the interfaces to come online.
Nodes sometimes show up as a mid1 entry when dtdlink and RF connected.
Sometimes the nodes will get the eth0 ip because wlan0 is not up yet.
Under Barrier Breaker the MainIP option is now supported as part of the uci system which allows us to restore using this setting.
We can now force the IP address that is claimed (wlan0) for the primary IP of the node.
Since a large number of the BBHNDev team has decided to create firmware fully independent of the BBHN Project the decision has been made to rebrand the firmware to differentiate from the origional BBHN work.
We would like to thank all those whom have worked on the BBHN firmware over the years and all those who continue to work on the firmware under AREDN(TM).
Program went GPLv3 last year but license text was never added to files
Default text to give credit to David as he is listed in all commits and to reference the BBHN Austin team at the same time as they were part of the group of HAM's that started this project.
Using the method suggested by Henning Rogge in 2014
{{{
1) remove file
2) wait 2 intervals
3) if file exists, go to 1)
4) restart olsr, then go to 1)
}}}
With the exception that we currently wait more than 2 intervals.
Even if the script hits a collision at the same time the file is being written the file will already exist from one of the previous writes or the current write.
Removing a file in use is safe as once the FD closes the file contents are fully released.
Additional Advantages:
* Should be more efficient to check if file exists instead of reading the file and comparing date stamps.
* Removing the Perl code moves us one step closer to retiring Perl in the future.
Removing the offset and increasing max power so we have full range avaliable to us.
This may not help us figure out the offset but will allow us a wider range of options.

Reported information and board information do not appear to line up, device will need further testing to verify actual details.
Max Power and Power Offset are of concern.

When a non mesh-gw node has a route via the WAN interface and through a mesh-gw it will choose the mesh-gw instead of the local WAN connection.and
We change the routing list to prefer the WAN link.
When the WAN is static configured the user will need to disable the WAN interface for the mesh internet to be chosen.
When the WAN is configured to dynamic the loss of a DHCP lease will allow the node to chose the remote mesh internet.
The simple solution would be to change the WAN to disabled and reboot to ensure a remote node is used instead if the local internet fails.
Thanks to Joe AE6XE and Clint AE5CA for pointing out this scenario.
By checking the "Keep Settings" box the node will run sysupgrade instead of mtd. Core settings are stored between installs and the _setup files are updated by pulling in missing items from the _setup.default files.
The olsrd watchdog module truncates and writes the latest timestamp every 5 seconds. The olsrd-watchdog script could catch the file during write causing an instant restart.
Changed to want 3 failures before restarting olsrd reducing the chance of collision based restarts.
