At a high level, this change does the following: - move the pluginchild actor to be a JSWindowActorChild - move the parent handling from browser-plugins into a JSWindowActorParent - move the crash handling from ContentCrashHandlers.jsm to the parent actor, using a `PluginManager` object. It needs to talk to the actors (and vice versa), so this seemed a better fit than spreading actor implementation details to other JSMs. - switch to using plugin IDs to identify plugins cross-process, instead of combinations of names or other properties of the plugin tag. As part of that, ensured plugin IDs are unique between "fake" plugins and the other ones. - drop support for having a notification for more than 1 plugin. We only support Flash, in practice, so there didn't seem to be much point in the added complexity of trying to support more than 1 thing. Some notes: - the previous implementation mixes runIDs (for NPAPI plugin process "runs") and GMP pluginIDs when doing crashreporting. AFAICT there is no guarantee these don't conflict, so I've split them out to avoid issues. There's a pluginCrashID object I pass around instead that has either a runID or pluginID. Happy to rename some more for clarity. - the previous implementation used `pluginInfo` and `plugin` for a bunch of different types of variables. I've tried to be consistent, where: * `pluginElement` is a DOM element for a plugin * `activationInfo` is a JS object used to track click to play state for a plugin * `plugin` is a plugintag as returned by the pluginhost service * `pluginCrashID` is an identifier for a crashed plugin (see previous point). - I'm still using broadcastAsyncMessage to tell the content processes about gmp plugin crashes and plugin crash submission updates, because there's no guarantee the actors are instantiated (for gmp plugins) nor can the parent easily find out which actors to talk to (for either gmp or npapi plugins). Open to suggestions there, too. I think our best bet might be moving that to IPDL-based IPC within the GMP code, but that feels like a separate bug.
