Message:

Separate list_t typedef from link_t (kernel part).

• list_t represents lists
• Use list_first(), list_last(), list_empty() where appropriate
• Use list_foreach() where possible
• Replace improper uses of list_prepend() with list_insert_after()
• Replace improper uses of list_append() with list_insert_before()
