xfs: rework online fsck incore bitmap [v24.5]

Browse source 
In this series, we make some changes to the incore bitmap code: First,
 we shorten the prefix to 'xbitmap'.  Then, we rework some utility
 functions for later use by online repair and clarify how the walk
 functions are supposed to be used.
 
 Finally, we use all these new pieces to convert the incore bitmap to use
 an interval tree instead of linked lists.  This lifts the limitation
 that callers had to be careful not to set a range that was already set;
 and gets us ready for the btree rebuilder functions needing to be able
 to set bits in a bitmap and generate maximal contiguous extents for the
 set ranges.
