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.

b17657d0cf bcachefs: Dont't call bch2_trans_begin_updates() in bch2_extent_update() 
Prep work for reflink - for reflink, we're going to be using

06ed855862 bcachefs: Add offset_into_extent param to bch2_read_extent() 
With reflink, we'll no longer be able to calculate the offset of the
data we want into the extent we're reading from from the extent pos and
the iter pos - we'll have to pass it in separately.

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.

01a0108f01 bcachefs: Fix a btree iter usage error 
previously, if the code traversed to the next btree node, that could
return an error (due to lock restarts) - which was not being checked
for.

fix is to rework it so it never iterates past the current leaf node, and
pops an assertion if it ever sees an error.
