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

4k buckets (though at that size we still waste almost half to internal
reserves)

6eac2c2e24 bcachefs: Change how replicated data is accounted 
Due to compression, the different replicas of a replicated extent don't
necessarily have to take up the same amount of space - so replicated
data sector counts shouldn't be stored divided by the number of
replicas.

c692399529 bcachefs: don't call bch2_bucket_seq_cleanup from journal_buf_switch 
journal_buf_switch is called from the foreground when getting a journal
reservation and thus is somewhat latency sensitive;
bch2_bucket_seq_cleanup has to run infrequently but is a bit expensive
when it does run.

Call it from the journal write path instead, and punt the journal write
to worqueue context.
