Subject: MINOR: lists: Implement function to convert list => mt_list and mt_list => list

MINOR: lists: Implement function to convert list => mt_list and mt_list => list

Implement mt_list_to_list() and list_to_mt_list(), to be able to convert
from a struct list to a struct mt_list, and vice versa.
This is normally of no use, except for struct connection's list field, that
can go in either a struct list or a struct mt_list.
