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? :)

This introduces four generic thread that services can
use in the system process:
- Background: part of the framework for all processes, for
work that is purely background (no timing constraint).
- UI: for time-critical display of UI.
- Foreground: normal foreground work.
- IO: performing IO operations.
I went through and moved services into these threads in the
places I felt relatively comfortable about understanding what
they are doing. There are still a bunch more we need to look
at -- lots of networking stuff left, 3 or so different native
daemon connectors which I didn't know how much would block,
audio stuff, etc.
Also updated Watchdog to be aware of and check these new
threads, with a new API for other threads to also participate
in this checking.

This is called from Settings that has a button to clear secure
adb public keys installed on the device.

The UsbDebuggingManager listens to adbd requests and displays a dialog
when the public key authentification fails, for the user to confirm if it
wants to allow USB debugging from the attached host. If the user chooses
to always allow USB debugging, the UsbDebuggingManager writes the public
key to adbd's config file so that the public key authenfication succeeds
next time.
