mod_http_oauth2: Record hash of client_id to allow future verification
RFC 6819 section 5.2.2.2 states that refresh tokens MUST be bound to the
client. In order to do that, we must record something that can
definitely tie the client to the grant. Since the full client_id is so
large (why we have this client_subset function), a hash is stored
instead.

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.
