mod_firewall: Initialize compiled chunk just once for all handlers This should fix a case where some stateful dependencies (such as throttles) produce separate instances for every call to new_handler(), leading to surprising behaviour (e.g. rules executed via JUMP CHAIN vs ::deliver would have separate rate limits). This also adds better error handling in case the compiled code fails to run for some reason.

summary: Advertise an external TURN service
...

This module advertises STUN/TURN service to clients via XEP-0215 (it utilizes
mod_external_services to do so, which will be automatically loaded by this
module and must be available).

This module is included with Prosody 0.12 but made available here for older
versions.

Documentation is available on the [Prosody site][doc:modules:mod_turn_external].
