jsonb_object_field_text and jsonb_array_element_text both contained identical copies of this code, so extract that into new routine JsonbValueAsText. This can also be used in other places, to measurable performance benefit: the jsonb_each() and jsonb_array_elements() functions can use it for outputting text forms instead of their less efficient current implementation (because we no longer need to build intermediate a jsonb representation of each value).
