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.
A module providing a streaming statistics interface like
[mod_statistics] but based on the new [statistics API][doc:statistics]
introduced in Prosody 0.10.
# Usage
To use, enable the built-in statistics like so:
```lua
statistics = "internal"
```
Then, in `modules_enabled`, replace `"statistics"` with
`"statistics_statsman"` and the various `"statistics_<something>"`
with equivalent `"measure_<something>"`.
