bcachefs: Redo data_update interface This patch significantly cleans up and simplifies the data_update interface. Instead of only being able to specify a single pointer by device to rewrite, we're now able to specify any or all of the pointers in the original extent to be rewrited, as a bitmask. data_cmd is no more: the various pred functions now just return true if the extent should be moved/updated. All the data_update path does is rewrite existing replicas, or add new ones. This fixes a bug where with background compression on replicated filesystems, where rebalance -> data_update would incorrectly drop the wrong old replica, and keep trying to recompress an extent pointer and each time failing to drop the right replica. Oops. Now, the data update path doesn't look at the io options to decide which pointers to keep and which to drop - it only goes off of the data_update_options passed to it.

bcachefs: Scan for old btree nodes if necessary on mount We dropped support for !BTREE_NODE_NEW_EXTENT_OVERWRITE but it turned out there were people who still had filesystems with btree nodes in that format in the wild. This adds a new compat feature that indicates we've scanned for and rewritten nodes in the old format, and does that scan at mount time if the option isn't set.
