The spec networking_general_api_information.html was moved
to api-ref in [0] but some of the links pointing to it
were not updated. This change makes all the refs consistent
and adds links where missing.
Also moved sync/async and bulk create sections lower to
group all the filtering, pagination and sorting sections
together since they are inter-related.
