* changes:
open("/dev/rtc0") failure in AlarmManagerService.setTime() should be non-fatal
Move time setting code from SystemClock to AlarmManagerService
On devices using /dev/rtc instead of /dev/alarm, updating the
time-of-day clock and RTC are separate syscalls. Hence the clock and
RTC could be left in inconsistent states if two threads called
SystemClock.setCurrentTimeMillis() simultaneously.
By moving this code into AlarmManagerService, we can put a global lock
around AlarmManagerService.setTime() and prevent the race condition.
Note that access to SystemClock.setCurrentTimeMillis() is now gated by
android.permission.SET_TIME, where before it was gated by filesystem
permissions (i.e., could the process write to /dev/alarm or /dev/rtc).

When a doze component has been specified in a config.xml resource
overlay, the power manager will try to start a preconfigured dream
whenever it would have otherwise gone to sleep and turned the
screen off. The dream should render whatever it intends to show
then call startDozing() to tell the power manager to put the display
into a low power "doze" state and allow the application processor
to be suspended. The dream may wake up periodically using the
alarm manager or other features to update the contents of the display.
Added several new config.xml resources related to dreams and dozing.
In particular for dozing there are two new resources that pertain to
decoupling auto-suspend mode and interactive mode from the display
state. This is a requirement to enable the application processor
and other components to be suspended while dozing. Most devices
do not support these features today.
Consolidated the power manager's NAPPING and DREAMING states into one
to simplify the logic. The NAPPING state was mostly superfluous
and simply indicated that the power manager should attempt to start
a new dream. This state is now tracked in the mSandmanSummoned field.
Added a new DOZING state which is analoguous to DREAMING. The normal
state transition is now: AWAKE -> DREAMING -> DOZING -> ASLEEP.
The PowerManager.goToSleep() method now enters the DOZING state instead
of immediately going to sleep.
While in the doze state, the screen remains on. However, we actually
tell the rest of the system that the screen is off. This is somewhat
unfortunate but much of the system makes inappropriate assumptions
about what it means for the screen to be on or off. In particular,
screen on is usually taken to indicate an interactive state where
the user is present but that's not at all true for dozing (and is
only sometimes true while dreaming). We will probably need to add
some more precise externally visible states at some point.
The DozeHardware interface encapsulates a generic microcontroller
interface to allow a doze dream for off-loading rendering or other
functions while dozing. If the device possesses an MCU HAL for dozing
then it is exposed to the DreamService here.
Removed a number of catch blocks in DreamService that caught Throwable
and attempted to cause the dream to finish itself. We actually just
want to let the process crash. Cleanup will happen automatically if
needed. Catching these exceptions results in mysterious undefined
behavior and broken dreams.

Treat arrays other than actual Object arrays (i.e. those whose component type
is actually Object) and the primitive arrays already handled specially by
Parcel as Serializable's.

The method handleMessage(Message msg) from mHandler variable was
not checking if the timer was cancelled, so
sendMessageDelayed(obtainMessage(MSG), delay) was keeping the
timer alive. The patch simply adds a boolean and checks if the
CountDownTimer was cancelled before calling
sendMessageDelayed(obtainMessage(MSG), delay)

Changes include
[x] Long is used to store native pointers
[x] Added new method obtain(long obj) to Parcel. Binder
uses this method instead of obtain(int obj).
[x] obtain(int) has been changed to throw unsupported
operation exception.

Transform DisplayManagerService into a SystemService and start cleaning
up other local services that it uses from window manager and input manager.
Clean up service thread initialization.
Remove unnecessary static variables from ActivityManagerService.
It's starting to become clear that we really need a better way to manage
service dependencies. Boot phases don't quite cut it.

Refactored SystemServer to get rid of a bunch of legacy cruft related
to how the ServerThread used to be started up.
Create system context first when system server starts. This removes
the tangled initialization order dependency that forced us to start
the activity manager service before most anything else.
Moved factory test related constants into the FactoryTest class.
Partially migrated Installer, ActivityManagerService, and
PowerManagerService to the new SystemService pattern. There's more
work to be done here, particularly around the lifecycle of the
power manager.

Long is used in android/os/MessageQueue class to store
pointers as native pointers can be 64-bit.
In addition, some minor changes have been done
to conform with standard JNI practice (e.g. use
of jint instead of int in JNI function prototypes)

The old documentation was kind of useless and not clear, so this is an
improvement.
In addition to this change, I think this method should probably be private
instead of public, especially since the values for code are private. But it's
too late to change that now. Also the method name is pretty poor, since it's
not actually reading anything. Something like "throwException" would be more
appropriate.
I'm open to suggestions on how to improve this situation. Maybe mark the
method as deprecated with a comment that it will be made private in the
future?

The original code was calling get() rather than valueAt(),
treating index as if it was a key.
