This patch adds some logic to extract the 6LoWPAN context information from the
6LoWPAN Context Option in the ICMPv6 dissector. This allows the user to
decompress 6LoWPAN traffic that has been contextually compressed without
needing to add contexts via the preferences dialog.

Contexts are stored in a GHashTable, and are indexed by context ID and PANID,
so simultaneous dissection of multiple PANs should be possible.

While I was at it, I also removed the use of the ieee802154_packet structure
from the 6LoWPAN dissector so that it now uses the ieee802154_hints instead,
and updated the 6lowpan-nd dissectors to version 19.
