1260828 - Remove the chromium event loop

Status: NEW

Our unholy combination of different event loops is an enormous pain, leading to everything from confusion (should I be using nsIRunnable or Task?) to outright bugs (when people don't realize that events of different types aren't necessarily ordered, or that PostDelayedTask is ... weird). We will unify around the XPCOM event loop/thread/etc machinery.

On XPCOM threads, the chromium event loop now just passes through dispatches to the XPCOM event queue.

For threads that are not XPCOM threads, we should make them XPCOM threads.  For the chromium threads that need special event processing logic (e.g. the IO thread, the miscellaneous UI threads) we should dispatch a runnable that runs some custom logic and calls NS_Process[Next|Pending]Events when appropriate to run the XPCOM event queue.
