Take care of updating from old component name, and don't let this happen
again.
Also tweak how we switch between static wallpapers to avoid introducing
a 4MB allocation in the system UI process when this happens -- we now
stop the current wallpaper service and start a new one, so we get a
brand new surface that we can draw only one time in to.

Nice to not load 4MB bitmaps in the system process.
Also, hey, with how we are now scrolling the surface instead of
the bitmap, there is no reason to keep that 4MB bitmap loaded in
to memory. So don't.
Unfortunately it looks like for some reason the VM is still
holding on to the bitmap. I'll need to figure out why. Later.

Applications now get the display size from the window manager. No
behavior should be changed yet, this is just prep for some real
changes.

The service connection to the previous live wallpaper is unbound when
a new wallpaper is effective. Although the service connection is
unbound it is not disconnected and its reference to wallpaper's
service and engine is still effective. This adds up to the total
JNI references and causes dalvik (hosting system_server) to abort.
Fix is to release the references in clearWallpaperComponentLocked.

No steps to repro, but makes the code more robust by using the standard
JournaledFile class and doing sanity checks on the input it reads.
This required moving the JournaledFile class in to the framework (and
we really should get rid of either it or AtomicFile, but they have
different recovery semantics so that is tough). Also went through and
cleaned up the file management in various places.

This is the framework part, moving classes around so the framework
no longer needs to link to android-common. Makes some APIs public,
others that didn't need to be public are private in the framework,
some small things are copied.
I am getting tired of writing package monitor code, realized this is missing in
a number of places, and at this point it has gotten complicated enough that I
don't think anyone actually does it 100% right so:
Introducing PackageMonitor.
Yes there are no Java docs. I am still playing around with just what this
thing is to figure out what makes sense and how people will use it. It is
being used to fix this bug for monitoring voice recognizers (integrating the
code from the settings provider for setting an initial value), to replace
the existing code for monitoring input methods (and fix the bug where we
wouldn't remove an input method from the enabled list when it got
uninstalled), to now monitor live wallpaper package changes (now allowing
us to avoid reverting back to the default live wallpaper when the current
one is updated!), and to monitor device admin changes.
Also includes a fix so you can't uninstall an .apk that is currently enabled
as a device admin.
Also includes a fix where the default time zone was not initialized early
enough which should fix issue #2455507 (Observed Google services frame work crash).
In addition, this finally introduces a mechanism to determine if the
"force stop" button should be enabled, with convenience in PackageMonitor
for system services to handle it. All services have been updated to support
this. There is also new infrastructure for reporting battery usage as an
applicatin error report.
Actually being able to configure a wallpaper relies on additional
work in the launcher and wallpapers that will be in another change.
Also note that this breaks all existing wallpapers, since they now
need to include a meta-data item about themselves. This also
will be fixed in another change.

Yet more work on improving the behavior of wallpapers. This fixes a few
problems in their lifecycle (corresponding change in the picker also
required for this), makes their animations better for hardware that supports
alpha fades, adds animations for the wallpapers themselves, eliminates
fixed size wallpapers, and adjusts the API for retrieving a wallpaper
bitmap to take care of scaling the raw wallpaper image to match the current
desired width and height.

This fixes a bunch of edge cases in updating the wallpaper's scroll position
and visibility when switching between wallpapers and traveling through the UI.
It also fixes some leaks of wallpaper tokens and windows.
- Do better about figuring out when to stop them and other related window
management.
- Fix problem where we were not redrawing the surface when the orientation
changed. This was the cause of the device hang.
- Recover if a live wallpaper is crashing repeatedly.
- Don't crash when someone tries to set a static wallpaper.
- Make the static wallpaper update correctly when the image changes.
This is all of the basic pieces:
- The WallpaperService now creates a surface with the window manager for its
contents.
- There is a simple service that displays a bitmap.
- The wallpaper manager takes care of starting and stopping the service.
- The window manager knows about wallpaper windows and how to layer them with
the windows that want to be shown on top of wallpaper.
Lots and lots of issues remain, but at this point you can actually write a
wallpaper service, select it in the UI, and see it behind an activity.
This is mostly refactoring, adding a new WallpaperManager class that takes care
of the old wallpaper APIs on Context, so we don't need to pollute Context with
various new wallpaper APIs as they are needed. Also adds the first little
definition of a wallpaper service, which is not yet used or useful.
