-Improved some Lua APIs:
* Moved several machine lifecycle callbacks to the notifier/subscriber model. The old callback registration model is still available for them for now, but prints a deprecation warning. * Added pre-save/post-load notifications. * Use a single allocated timer rather than one anonymous timer per waiter. Waiters no longer prevent saved states from being loaded. * Clean up outstanding waiters on stop or state load rather than just leaking them. * Started documenting parts of the emulator interface object that should be relatively stable. -imagedev/avivideo.cpp: Fixed an object leak on unload. Also changed some other media image devices to use smart pointers.
