MINOR: mt_lists: Add new macroes.

Add a few new macroes to the mt_lists.
MT_LIST_LOCK_ELT()/MT_LIST_UNLOCK_ELT() helps locking/unlocking an element.
This should only be used if you know for sure nobody else will remove the
element from the list in the meanwhile.
mt_list_for_each_entry_safe() is an iterator, similar to
list_for_each_entry_safe().
It takes 5 arguments, item, list_head, member are similar to those of
the non-mt variant, tmpelt is a temporary pointer to a struct mt_list, while
tmpelt2 is a struct mt_list itself.
MT_LIST_DEL_SELF() can be used to delete an item while parsing the list with
mt_list_for_each_entry_safe(). It shouldn't be used outside, and you
shouldn't use MT_LIST_DEL() while using mt_list_for_each_entry_safe().
