Btrfs: tree-checker: detect file extent items with overlapping ranges
Having file extent items with ranges that overlap each other is a serious issue that leads to all sorts of corruptions and crashes (like a BUG_ON() during the course of __btrfs_drop_extents() when it traims file extent items). Therefore teach the tree checker to detect such cases. This is motivated by a recently fixed bug (race between ranged full fsync and writeback or adjacent ranges).
