mame/plugins/discord/init.lua
Vas Crabb b67b969bf0 -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.
