Adds an optimization for checking whether a looper is stuck, with a new Looper method to see if its thread is currently idle. This will allow us to put a large number of loopers in the monitor efficiently, since we generally won't have to do a context switch on each of them (since most looper threads spend most of their time idle waiting for work). Also change things so the system process's main thread is actually running on the main thread. Because Jeff asked for this, and who am I to argue? :) Change-Id: I12999e6f9c4b056c22dd652cb78c2453c391061f
