AbdAlRahman Gad c16141eda5 ndp.c: Turn NDP responder into more declarative implementation
- Add structs for NA, RA, NS, MTU, prefix info, option header,
  link-layer address, RDNSS, DNSSL and link-layer for RA message.

- Turn NA message from purely imperative, going byte by byte,
  to declarative by filling it's struct.

- Turn part of RA message into declarative.

- Move packet_add() to be before the call of ndp() in tap6_handler()
  if the protocol of the packet  is ICMPv6.

- Add a pool of packets as an additional parameter to ndp().

- Check the size of NS packet with packet_get() before sending an NA
  packet.

- Add documentation for the structs.

- Add an enum for NDP option types.
