Kent Overstreet 8d84260ec1 bcachefs: data move path should not be trying to move reflink_p keys 
This was spotted when the move_extent() path tried to allocate a bio for
a reflink_p extent, but adding pages to the bio failed because we
overflowed bi_max_vecs. Oops.

Kent Overstreet 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.

Kent Overstreet 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.

Kent Overstreet 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.

This new helper for the move path avoids creating a new CRC entry when
we already have one that matches the pointer being added.
