The IEEE 802.15.4 protocol can operate on one of two types of addresses, but it
is most common to use the 16-bit short addressing mode. This presents a problem
when performing packet decryption, since it is required to know the 64-bit
extended address of the sender in order to properly decrypt a packet (it's a
part of a seed/nonce to the CCM* cipher).

This patch adds a hash table that stores any short-to-extended address mappings
that the dissector finds for later use during packet decryption. I've also
added a UAT so the user can manually add address pairs if needed.

In order to demonstrate this patch in action, decryption needs to be fixed
(Patches for bug 4505 need to be applied).
