6lowpan: add generic 6lowpan netdev private data
This patch introduced the 6lowpan netdev private data struct. We name it lowpan_priv and it's placed at the beginning of netdev private data. All lowpan interfaces should allocate this room at first of netdev private data. 6LoWPAN LL private data can be allocate by additional netdev private data, e.g. dev->priv_size should be "sizeof(struct lowpan_priv) + sizeof(LL_LOWPAN_PRIVATE_DATA)".
