mod_compat_roles: Fix attempt to index a nil value #1847
permissions[] is not a map with role names as keys since 817bc9873fc2
but instead a level with host names were added. This was likely an
oversight.
Refactored towards railroad.

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].
