Files are simple serialized bytes prefaced by lengths. File is hashed to verify integrity. This was also a good way preventing unexpected errors when trying to crash the parser by having it load a different file. This change includes some refactoring that was necessary: - It 'fixes' looking at the wrong thread's authentiction. This is still wrong though. It will be fixed by a thread local pointer in the next commit. - Deadlocks with yourself are handled in rwlockguard. - QoSPacketQueue is now a class. - Probably other tweaks.

Also include a few stats.

My IDE didn't understand them for finding symbols, apparently.

This includes a timer mechanism.

Connected to this is preventing duplicate subscriptions. It's a bit unclear what to do when you get a subscription for the same topic with a different QoS? Change the Qos? Ignore?
-
Also includes fixes to packet parsing that I couldn't make a separate commit for. When it comes to QoS 1, these things are still left, off the top of my head: - vector for qos queue? It helps with ordering and is CPU cache friendly. - Store subscription QoS. - Do retained messages have QoS? - Give session client's name, to access it later.

In preparation for clean session and qos.
