Map iteration order is not guaranteed by Go, so it's an error to iterate
over a map in places where maintaining the same ordering is important.
This change replaces the map of simulcastRid{} with an array of the same
type. The simulcastRid{} type is extended to hold the rid-id which
previously was used as the key in the map.
Accesses to the map are replaced with range loops to find the desired
rid-id for each case.
Fixes #2838
