Replace publicroomsapi with a combination of clientapi/roomserver/currentstateserver (#1174)
* Use content_value instead of membership

* Fix build

* Replace publicroomsapi with a combination of clientapi/roomserver/currentstateserver

- All public rooms paths are now handled by clientapi
- Requests to (un)publish rooms are sent to the roomserver via `PerformPublish`
  which are stored in a new `published_table.go`
- Requests for public rooms are handled in clientapi by:
    * Fetch all room IDs which are published using `QueryPublishedRooms` on the roomserver.
    * Apply pagination parameters to the slice.
    * Do a `QueryBulkStateContent` request to the currentstateserver to pull out
      required state event *content* (not entire events).
    * Aggregate and return the chunk.

Mostly but not fully implemented (DB queries on currentstateserver are missing)

* Fix pq query

* Make postgres work

* Make sqlite work

* Fix tests

* Unbreak pagination tests

* Linting

// The purpose of this test is to check that when there are missing prev_events and we still haven't been able to fill
// in the hole with /get_missing_events that the state BEFORE the events we want to persist is fetched via /state_ids
// and /event. It works by setting PrevEventsExist=false in the roomserver query response, resulting in
// a call to /get_missing_events which returns 1 out of the 2 events it needs to fill in the gap. Synapse and Dendrite
// both give up after 1x /get_missing_events call, relying on requesting the state AFTER the missing event in order to
// continue. The DAG looks something like:
// FE GME TXN
// A ---> B ---> C ---> D
// TXN=event in the txn, GME=response to /get_missing_events, FE=roomserver's forward extremity. Should result in:
// - /state_ids?event=B is requested, then /event/B to get the state AFTER B. B is a state event.
// - state resolution is done to check C is allowed.
// This results in B being sent as an outlier FIRST, then C,D.
