batman-adv: netlink: add translation table query

Browse Source 
This adds the commands BATADV_CMD_GET_TRANSTABLE_LOCAL and
BATADV_CMD_GET_TRANSTABLE_GLOBAL, which correspond to the transtable_local
and transtable_global debugfs files.

The batadv_tt_client_flags enum is moved to the UAPI to expose it as part
of the netlink API.

* the other nodes in the network. To achieve this goal these flags are included
* in the TT CRC computation.
