Make surface management between SurfaceView and the window manager
much more controlled, to ensure that SurfaceView always gets to report
the current surface is destroyed before the window manager actually
destroys it.
Also a small tweak to allow windows that have a wallpaper background
to still have a preview window. This makes launching home after it
has been killed feel much more responsive.

This came up from bug #5601885: Memory increase (leak?) in system_server
Stingray MR1
This isn't *really* a leak in the system process -- it is a leak in an
application process that is causing the system process to keep around
a bunch of ActivityRecord objects longer than it should, until that app
process is ultimately killed.
Unfortunately these days leaking an ActivityRecord also often means
leaking a thumbnail, which is a big slab of memory.
So make the activity manager better about this, using a weak reference
from the handle the object has so we can still clean away most of the
state associated with the ActivityRecord even if the client side leaks
its own reference.

...should not be restarted when rotating screen on xoom
This was a side-effect of a previous fix to compute the screen layout
config class based on the actual space available to the application, not
the raw display size. On a device like Xoom, the system bar causes us
to switch between LONG and NOTLONG depending on whether the system bar
is on the short or long side of the screen.
To fix this, we now compute the screen layout class the same way
"smallest width" is computed: looking at all of the possible rotations
and using the smallest of them all. In addition to preventing the device
from toggling between long and notlong on a Xoom-like screen, this will
also avoid other possible undersireable behavior like changing screen
layout size when rotating.
This does mean that Xoom is no longer considered a long screen even when
in landscape, because it is not a long screen in portrait.

Previously, the input dispatch rate was capped by default to 55.
This worked fine for systems with a refresh rate of 55 or lower. But on
devices with a higher frame rate (such as stingray at 60 fps), we do not
receive events as fast as the rendering system wants to redraw the frames, so
we would occasionally miss events between frames, resulting in a visual
stutter during drag operations where the dragged object would essentially
stay still for a frame.
This fix increases the default rate to 90, or 1.5 times the highest typical
refresh rate of our devices.

The ScreenShot layer is now created hidden. The screenshot itself
is aquired during the transaction when the layer is made visible.
This guarantees the screenshot and the layer happen atomically
with respect to screen updates.

whether it is being showm, allowing us to more aggressively free its
memory when not shown.
- The activity display time is no longer delayed by the activity

- Improved some documentation on Loader to be clear about some methods
that apps should not normally call.
- FrameworkPerf test now allows you to select individual tests to run.

Introduce a new concept of "B" services. All running services are
classified as either A or B. B services are later in the LRU list.
Their oom_adj is after the home app. This allows us to better pick
services to kill based on how long they have running, and should
reduce the amount that we end up killing the home app.
This temporarly turns on a debug log when the oom_adj of a process
is changed. Sorry, I know it is noisy. This is needed to try to
track down why some processes are being killed.
Also add a flag to the SyncManager's service binding to allow the
syncing process to be more aggressively killed if it has done UI.
This is to address cases we have seen where sync is causing an 80MB
gmail process to be kept around, preventing other process from running.
Now what will happen is that the syncing process will aggressively be
killed by the system, and can then be restarted in a much lighter-weight
state.
Do a little tweak in the power manager to allow us to still do smooth
brightness changes even when the fancy TV off animation is in use.
And get rid of a debug log in the window manager that was accidentally
left in.

Swiping the home screen causes the WindowManagerService to do
a bunch of work to keep the wallpapers in sync. First, it lays out
and places all windows. Also, it notifies the SystemUI process that
the wallpaper position has changed.
The layout/place operation is too much work - we only need to set
the position values for the wallpaper, not relayout the whole system.
The notification mechanism must exist, but should be optional. Most
wallpapers don't care (especially static ImageWallpapers). So we'll
give them a new API (WallpaperService.Engine.setWantsOffsets()) to
allow wallpapers to opt out of this process and avoid the performance
overhead.

If an app takes the 5-second ANR timeout before responding to a
drop, but then recovers, we were inappropriately throwing an
exception back at it for having acknowledged the drop after we'd
abandoned the operation out from under it. Now we let such
responses slide without taking any punitive action: the app is
still okay, and the drag/drop operation was cleanly terminated
already anyway.

It is no longer sufficient to check the value of
internal.R.bool.config_showNavigationBar to determine if a
navigation bar (separate from the status bar) is shown on a
device, because the emulator needs to be able to override
this value (now possible by setting qemu.hw.mainkeys to "1"
or "0", for navbar or no navbar, respectively).
This logic is now contained in PhoneWindowManager, and any
clients wishing to know whether the system has a software
nav bar should consult the new hasNavigationBar() method.

- Fix issue where a crash in system UI would cause the crash

else.

...the "Complete action using" dialog
When an application goes idle, it sends back to the activity manager
the configuration it last used, to make sure the two don't get out
of sync. Fix a bunch of edge cases here in dealing with that, and
be sure to also send the current configuration when launching an
activity so the client is always up-to-date when launching.
Also a small fix to not show the upgrading dialog during first boot.

The PhoneWindowManager is now responsible for hiding and showing
the nav bar.
For hiding, it just moves it off the screen (easy way to get a
nice slide animation on and off). At the same time, we use a
new WM facility to put up a fake input window to capture all
touch events.
When a touch event is received, we force the system UI to clear
the navigation hiding bit so it will be shown again.
This removes a bunch of code from the system UI for hiding and
showing the nav bar. Also removes the code calling from userActivity()
to the system UI, which was bad. (Also no longer using userActivity()
fixes bugs around re-showing the nav bar due to key presses and
other wrong things.)

This cleans up how ui flags are managed between the client and window manager.
It still reports the global UI mode state to the callback, but we now only clear
certain flags when the system goes out of a state (currently this just means the
hide nav bar mode), and don't corrupt other flags in the application when the
global state changes.
Also introduces a sequence number between the app and window manager, to avoid
using bad old data coming from the app during these transitions.
