mod_muc_markers: Add option for @id rewriting, default off (may break some clients)
XEP-0333 was updated to clarify that stanza-id should be used
instead of the 'id' attribute when in a MUC. Some clients still
use the id attribute, which is why we were rewriting it.
Rewriting is bad because mod_muc advertises stable_id, indicating
that Prosody does *not* rewrite ids. Recent versions of Conversations
actually depend on this being true.
All clients should migrate to using stanza-id for markers. See XEP-0333.

This module compares the memory usage reported by Lua before and after each event and reports it to the log if it exceeds the configuration setting `log_memory_threshold` (in bytes). ``` lua log_memory_threshold = 20*1024 ``` If you are looking to identify memory leaks, please first read [Three kinds of memory leaks](https://blog.nelhage.com/post/three-kinds-of-leaks/). Prosody runs on Lua which uses automatic memory management with garbage collection, so the numbers reported by this module are very likely to be useless for the purpose of identifying memory leaks. Large, but temporary, increases in memory usage can however highlight other kinds of performance problems and sometimes even provide hits for where to look for memory leaks.
