bcachefs: Factor out fs-common.c This refactoring makes the code easier to understand by separating the bcachefs btree transactional code from the linux VFS code - but more importantly, it's also to share code with the fuse port. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev>

bcachefs: Plumb through subvolume id To implement snapshots, we need every filesystem btree operation (every btree operation without a subvolume) to start by looking up the subvolume and getting the current snapshot ID, with bch2_subvolume_get_snapshot() - then, that snapshot ID is used for doing btree lookups in BTREE_ITER_FILTER_SNAPSHOTS mode. This patch adds those bch2_subvolume_get_snapshot() calls, and also switches to passing around a subvol_inum instead of just an inode number.
