Now that we have the logged operations btree, we can make finsert/fcollapse atomic w.r.t. unclean shutdown as well. This adds bch_logged_op_finsert to represent the state of an finsert or fcollapse, which is a bit more complicated than truncate since we need to track our position in the "shift extents" operation.
