Thank you, Intari, for a patch that implements the missing pieces of
Http-in and makes the host name for URL generation configurable. Applied with changes: llGetSimulatorHostname was not changed, because the change breaks existing behavior and carries a data exposure risk. That value needs to be configurable, the proposed fixed change is not acceptable.
