                * javax/swing/text/GapContent.java
                (GapContentPosition.GapContentPosition): Removed constructor.
                (Mark): Made subclass of WeakReference to refer directly to
                the associated position.
                (Mark.refCount): Removed.
                (Mark.Mark(int,GapContentPosition,ReferenceQueue):
                New constructor. Used to reference a position and register the
                reference queue.
                (Mark.Mark(index)): Call super and don't adjust mark offset.
                (Mark.compareTo): Removed.
                (Mark.equals): Removed.
                (Mark.getOffset): Return at least null. Removed assert.
                (Mark.getPosition): New helper method.
                (garbageMarks): New field.
                (positions): Removed.
                (searchMark): New field.
                (GapContent): Removed init of positions map.
                (addImpl): New helper method.
                (adjustPositionsInRange): Removed.
                (compare): New helper method.
                (createPosition): Rewritten for new datastructures. This now
                performs a much more efficient binary search for finding
                a position at the requested offste.
                (garbageCollect): Rewritten to collect unused marks.
                (getPositionsInRange): Adjusted for new data structures.
                (removeImpl): New helper method.
                (replace): Use new addImpl() and removeImpl() helper method for
                correctly adjusting the positions and gap.
                (search): Rewritten. Implements a more suitable binary search.
                (searchFirst): New helper method.
                (setPositionsInRange): Removed.
                (shiftEnd): Update the marks here.
                (shiftGap): Update the marks here.
                (shiftGapEndUp): Update the marks here.
                (shiftGapStartDown): Update the marks here.
