The system now keeps a tag of the last version (just an arbitrary string)
that the setup wizard was run for. If this is different than the current
one in the setup wizard, then setup is launched at boot.
This introduces a new intent action for the part of the setup wizard that
gets run for an ungrade, which the system uses to find its current version
tag for comparing against what was last stored. It is up to the launched
setup activity update the stored setting to reflect its current value,
once it is happy.
Fiddle around with event dispatching to remove calling permissions when we
enter event injection, and prevent callers from going to the PhoneWindowManager's
event processing code unless they are allowed at that point.
Applications can now declare that they support small, normal, or
large screens. Resource selection can also be done based on these
sizes. By default, pre-Donut apps are false for small and large,
and Donut or later apps are assumed to support all sizes. In either
case they can use <supports-screens> in their manifest to declare
what they actually support.
This also includes some changes to the window manager permission checks. Almost all of these
are to make it most testable (through an exception on a permission failure), though there is
one permission check that needed to be added: updateOrientationFromAppTokens().
We are decreasing CPU usage at the cost of event latency. Events are queued up
and released to the app at the specified rate. You can
experiment with different values via:
adb shell setprop windowsmgr.max_events_per_sec 35
The new value is picked up when you let go and retouch the screen. No
reboot needed.
Also the following changes were made after profiling:
- In WindowManagerService, limit the call to userActivity() when we
have a flood touch events.
- In PowerManagerService, skip checking of permission if the caller
is system user.
- In PowerManagerService, integrated the functionality of gatherState()
into reactivateWakeLocksLocked(). They loop through the same data
structure and are called back to back.

There are three major classes of changes here:
- Avoid writing lines where their values are often empty, false, or some other typical thing.
- Use partial writes to the PrintWriter to avoid creating temporary strings.
- Use StringBuilder where we need to generate real String objects (and where possible cache the result).
#1748954 (New status bar fades into all white background): FrameLayout wasn't updating its foreground drawable when its padding changed, which would happen as the status bar is shown and hidden. To fix this I also ended up fixing a problem in the view debug stuff where we couldn't get a bitmap for a view that is the full screen size because it is too big... actually I just went ahead and added another function to snapshot the view hierarchy which works a lot better for us anyway.
#1737952 (Home screen icons overlap with the notification bar after exiting any camera app): Originally I punted this because it only happened in rare situations, but now that home is always portrait it happens a lot more so it is more important to fix. This involved a few things to clean up hiding/showing the status bar:
- We now determine when to hide and show it during layout, which allows us to do this at the time it is actually needed rather than during animation after we can actually catch it for the initial display of a window. This required tweaking the layout API so the policy can request a second layout pass if needed.
- When doing layout, we are now much more aggressive about skipping the layout of windows. Basically anything that we know will be hidden in the near future is ignored for layout, so that it doesn't glitch as it is transfered out of the screen. The theory being that it is better to leave it as it was originally placed while we are transitioning it out, than to switch it to something slightly more correct.

Adds stats for:
- Number of raw user events that have happened in the system.
- Number of times user activity has been reported, dividied by UID and type of activity.
- Duration of screen brightness levels in 4 buckets.
- Per-UID tracking of who has turned on Wifi and how long we can attribute it being on because of them.

Also do most of the work for issue #1732012 (Only show screen rotation animation when triggered by sensor). This just needs to be hooked up to the surface flinger API when that appears.
