mod_openid, mod_json_streams: Remove modules depending on obsolete net.httpserver API These have not been updated for a long time and do not work with Prosody versions from recent years, which is a good indication they are not being used.

This module writes out a traceback to `traceback.txt` in Prosodys data
directory (see `prosodyctl about`) when the signal `SIGUSR1` is
received. This is useful when debugging seemingly frozen instances in
case it is stuck in Lua code.
