batman-adv: include the sync-flags when compute the global/local table CRC
Flags covered by TT_SYNC_MASK are kept in sync among the nodes in the network and therefore they have to be considered while computing the global/local table CRC. In this way a generic originator is able to understand if its table contains the correct flags or not. Bits from 4 to 7 in the TT flags fields are now reserved for "synchronized" flags only. This allows future developers to add more flags of this type without breaking compatibility. It's important to note that not all the remote TT flags are synchronised. This comes from the fact that some flags are used to inject an information once only.
