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.

# Introduction

This module writes out a traceback to a file when a chosen signal (by default
`SIGUSR1`) is received. It can be useful to diagnose cases where Prosody is
unresponsive.

# Configuration

`debug_traceback_filename`
:   The name of the file to write the traceback to. Some variables
    are supported, see [mod_log_ringbuffer] docs for more info. Defaults
    to `{paths.data}/traceback-{pid}-{count}.log`.

`debug_traceback_signal`
:   The name of the signal to listen for. Defaults to `SIGUSR1`.

# Compatibility

Prosody 0.12 or later.
