mod_muc_markers: Prevent any markers from reaching the archive, even if untracked
Original intention was to leave alone things that this module isn't
handling. However markers in archives are just problematic without
more advanced logic about what is markable and what is not. It also
requires a more advanced query in mod_muc_rai to determine the latest
markable message instead of the latest archived message.
I'd rather keep the "is archivable" and "is markable" definition the
same for simplicity. I don't want to introduce yet another set of rules
for no reason.
No markers in MAM.

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.
