Subject: [PATCH] Cleanup MCUtils patch for chunk system

Remove utilities that are unused, as well as replacing
the full chunk map with a concurrentutil implementation.

Additionally, fix the addition/removal of chunks to/from the
full chunk map so that getChunkIfLoaded correctly returns a
non-null chunk when calling the load or unload events.
