...phase & callback API
I realized there were a few things wrong with what was there. The new
ACTION_USER_STARTING was not being sent for the first user at boot, and
there was an existing problem where ACTION_USER_STARTED was sent every
time there was a user switch.
Also improved some debug output of broadcasts to make it easier to see
what is going on in this stuff, and better reporting of why a service
couldn't be started.
