1. batman-adv: Don't accept TT entries for out-of-spec VIDs …

   The internal handling of VLAN IDs in batman-adv is only specified for
   following encodings:
   
   * VLAN is used
     - bit 15 is 1
     - bit 11 - bit 0 is the VLAN ID (0-4095)
     - remaining bits are 0
   * No VLAN is used
     - bit 15 is 0
     - remaining bits are 0
   
   batman-adv was only preparing new translation table entries (based on its
   soft interface information) using this encoding format. But the receive
   path was never checking if entries in the roam or TT TVLVs were also
   following this encoding.
   
   It was therefore possible to create more than the expected maximum of 4096
   + 1 entries in the originator VLAN list. Simply by setting the "remaining
   bits" to "random" values in corresponding TVLV.

2. batctl: Dynamically select header format in netlink_print_neighbors …

   The netlink_print_neighbors() function previously used a static header
   format, which did not account for variations between the neighbor list
   output from different BATMAN routing algorithms (BATMAN_IV vs. BATMAN_V).
   
   This change ensures that the table header output in `batctl n` is accurate
   for both BATMAN routing algorithms.
