mod_log_ringbuffer: Detach event handlers on logging reload (thanks Menel)
Otherwise the global event handlers accumulate, one added each time
logging is reoladed, and each invocation of the signal or event triggers
one dump of each created ringbuffer.

summary: Throttle authentication attempts with optional tarpit
...
Introduction
============
This module lets you put a per-IP limit on the number of failed
authentication attempts.
It features an optioanal
[tarpit](https://en.wikipedia.org/wiki/Tarpit_%28networking%29), i.e.
waiting some time before returning an "authentication failed" response.
Configuration
=============
``` {.lua}
modules_enabled = {
-- your other modules
"limit_auth";
}
limit_auth_period = 30 -- over 30 seconds
limit_auth_max = 5 -- tolerate no more than 5 failed attempts
-- Will only work with Prosody trunk:
limit_auth_tarpit_delay = 10 -- delay answer this long
```
Compatibility
=============
Requires 0.9 or later. The tarpit feature requires Prosody trunk.
