mackie: redesign display logic entirely
Strips now maintain a pair of pending display strings (upper and lower).
A periodic timeout writes the pending value to the actual hardware if it
differs from the current string. This new design makes it easy to put a
message on the display and then after some period of time, revert to
whatever was there before.
