* Review comments @Kegsay
* Per-room input mutex
* GetMembership should use transaction when assigning state key NID
* Actually use writer transactions rather than ignoring them
* Limit per-room mutexes to Postgres
* Flip the check in InputRoomEvents
* Always defer *sql.Rows.Close and consult with Err
database/sql.Rows.Next() makes sure to call Close only after exhausting
result rows which would NOT happen when returning early from a bad Scan.
Close being idempotent makes it a great candidate to get always deferred
regardless of what happens later on the result set.
This change also makes sure call Err() after exhausting Next() and
propagate non-nil results from it as the documentation advises.
Closes#764
