99aaf57000 bcachefs: Refactor various code to not be extent specific
With reflink, various code now has to handle both KEY_TYPE_extent
or KEY_TYPE_reflink_v - so, convert it to be generic across all keys
with pointers.

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.

71c9e0ba42 bcachefs: bch2_extent_ptr_decoded_append()
This new helper for the move path avoids creating a new CRC entry when
we already have one that matches the pointer being added.

b0004d8dfa bcachefs: Factor out btree_key_can_insert()
working on getting rid of all the reasons bch2_insert_fixup_extent() can
fail/stop partway, which is needed for other refactorings.

One of the reasons we could have to bail out is if we're splitting a
compressed extent we might need to add to our disk reservation - but we
can check that before actually starting the insert.
