Cache some recently used entity capability lookups in memory
Previously any entity capability lookup was only cached
on the disk. This meant that even for a cache hit, you would
read from disk and parse the disco info XML in the cache,
to return the result.
This commit adds an addition LRUCache based in-memory cache.
This extends the EntityCapsProvider API with a non-const
method, i.e. getCapsCached, which allows active caching
of results from the disk cache.
Test-Information:
All unit tests pass on macOS 10.12.3.
This noticeably speeds up the duration of a join of a large
MUC room, i.e. about 160 occupants, to about half of the
previous duration.
