This CL aims to fix two race conditions: 1. When statsd restarts after a crash, the ordering of sayHiToStatsd and binderDied is not guaranteed. However, previously, we assumed that binderDied would get called first and reset sStatsd to null. To solve, we don't assume a function ordering and don't throw an error message in sayHiToStatsd if sStatsd is not null. 2. When statsd was linked to death, the death recipient was not informed about all broadcast receivers. Thus, the death recipient might have known only a partial list of receivers when #binderDied was triggered. To solve, we make sure that the death recipient knows about all receivers before we link to death.
