RESUME: check the AFC lane, add AFC_CLEAR_ALL_MESSAGES

Browse Source 
PAUSE stores the lane the print needs (AFC's next_lane during a failed
tool change, otherwise the loaded lane). RESUME stops with an error when
another lane or none is loaded; RESUME LANE_CHECK=0 skips the check.

AFC_CLEAR_ALL_MESSAGES clears AFC's whole message queue
(AFC_CLEAR_MESSAGE only removes the first message).
