  1. gnrc_netif: introduce is_6lo() as alias to is_6ln() 

    Preparation step to introduce a semantic difference between an
interface being a 6Lo interface and a 6LN according to RFC 6775 [[1]]
(i.e. performs Neighbor Discovery as defined there).

  3. gnrc_ipv6: use is_6lo() instead of is_6ln() 

    We want to check if the interface is an interface requiring the 6Lo
adaptation layer, not if it is a 6LN according to RFC 6775 [[1]].

  4. gnrc_netif: introduce 6LN flag 

    This makes it dynamically configurable if an interface actually want's
to use 6Lo ND (according to RFC 6775) or not.

  5. gnrc_netif: distinct is_6lo() and is_6ln() 

    The functions now are semantic distinct:

- gnrc_netif_is_6lo(): the interface is a 6Lo interface
- gnrc_netif_is_6ln(): the interface is using Neighbor Discovery
  according to RFC 6775

  6. tests/gnrc_ipv6_nib_6ln: add msb-430* to BOARD_INSUFFICIENT_MEMORY 

    The new fixed code paths with the 6LN/6Lo distinction make this
application too big for the given boards
