b2ca9903cd bcachefs: Fix extent_to_replicas()
This needs to match bch2_mark_extent()/bch2_trans_mark_extent() in
buckets.c

37954a275f bcachefs: Limit pointers to being in only one stripe
This make the disk accounting code saner, and it's not clear why we'd
ever want the same data to be in multiple stripes simultaneously.

eab32c8e4e bcachefs: Fix validation of replicas entries
When an extent is erasure coded, we need to record a replicas entry to
indicate that data is present on the devices that extent has pointers to
- but nr_required should be 0, because it's erasure coded.

df5d4dae0b bcachefs: Fixes for replicas tracking
The continue statement in bch2_trans_mark_extent() was wrong - by
bailing out early, we'd be constructing the wrong replicas list to
update. Also, the assertion in update_replicas() was wrong - due to
rounding with compressed extents, it is possible for sectors to be 0
sometimes.

Also, change extent_to_replicas() in replicas.c to match the replicas
list we construct in buckets.c.

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.
