This patch series introduces new per-btree accounting counters and uses them for (hopefully) accurate progress reporting in recovery passes. Also includes various assorted bugfixes.
The commit "Relax restrictions on the number of accounting counters" is optional, but will likely greatly improve the upgrade/tools version mismatch experience. Without it, all bree usage accounting will be thrown out and rebuilt on any version mismatch. The commit "bcachefs_metadata_version_btree_node_accounting" introduces the format change along with upgrade/downgrade table entries. The first two commits are drive-by fixes/improvements.
