This is especially useful if there are no claims yet, but we still want to know which gateways are using bridge loop avoidance in the network.

for consistency reasons within the code and with the documentation, we should always call it "claim" and "unclaim".

The structure batadv_priv grows everytime a new feature is introduced. It gets hard to find the parts of the struct that belongs to a specific feature. This becomes even harder by the fact that not every feature uses a prefix in the member name.

The variables for bridge loop avoidence, gateway handling, translation table and visualization server are moved into separate structs that are included in the bat_priv main struct.

With the current TT mechanism a new client joining the network is not immediately able to communicate with other hosts because its MAC address has not been announced yet. This situation holds until the first OGM containing its joining event will be spread over the mesh network.

This behaviour can be acceptable in networks where the originator interval is a small value (e.g. 1sec) but if that value is set to an higher time (e.g. 5secs) the client could suffer from several malfunctions like DHCP client timeouts, etc.

This patch adds an early detection mechanism that makes nodes in the network able to recognise "not yet announced clients" by means of the broadcast packets they emitted on connection (e.g. ARP or DHCP request). The added client will then be confirmed upon receiving the OGM claiming it or purged if such OGM is not received within a fixed amount of time.
