885678f68d bcachefs: Kill direct access to bi_io_vec
Switch to always using bio_add_page(), which merges contiguous pages now
that we have multipage bvecs.

1dd7f9d98d bcachefs: Rewrite journal_seq_blacklist machinery
Now, we store blacklisted journal sequence numbers in the superblock,
not the journal: this helps to greatly simplify the code, and more
importantly it's now implemented in a way that doesn't require all btree
nodes to be visited before starting the journal - instead, we
unconditionally blacklist the next 4 journal sequence numbers after an
unclean shutdown.

26609b619f bcachefs: Make bkey types globally unique
this lets us get rid of a lot of extra switch statements - in a lot of
places we dispatch on the btree node type, and then the key type, so
this is a nice cleanup across a lot of code.

Also improve the on disk format versioning stuff.

8b335baef2 bcachefs: Assorted fixes for running on very small devices
It's now possible to create and use a filesystem on a 512k device with
4k buckets (though at that size we still waste almost half to internal
reserves)
