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.

e222d206f2 bcachefs: Fix ec_stripes_read() 
Change it to not mark keys that will be overwritten by keys in the
journal - this fixes a bug where we pop an assertion in
bucket_set_stripe() because of a stale pointer - because the stripe that
has the stale pointer has been deleted.

This code could be factored out and used elsewhere, at some point.

97fd13ad76 bcachefs: Don't try to delete stripes when RO 
We weren't checking for errors when trying to delet stripes, which meant
ec_stripe_delete_work() would spin trying to delete the same stripe over
and over.

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.
