There are potentially very many Handlers owned by services
that should not be blocked by barriers introduced by UI traversals
occurring on the same thread (if that ever happens).
Add some convenience constructors to make it easy to switch
these Handlers over to being async.

This add a new per-user state for an app, indicating whether
it is installed for that user.
All system apps are always installed for all users (we still
use disable to "uninstall" them).
Now when you call into the package manager to install an app,
it will only install the app for that user unless you supply
a flag saying to install for all users. Only being installed
for the user is just the normal install state, but all other
users have marked in their state for that app that it is not
installed.
When you call the package manager APIs for information about
apps, uninstalled apps are treated as really being not visible
(somewhat more-so than disabled apps), unless you use the
GET_UNINSTALLED_PACKAGES flag.
If another user calls to install an app that is already installed,
just not for them, then the normal install process takes place
but in addition that user's installed state is toggled on.
The package manager will not send PACKAGE_ADDED, PACKAGE_REMOVED,
PACKAGE_REPLACED etc broadcasts to users who don't have a package
installed or not being involved in a change in the install state.
There are a few things that are not quite right with this -- for
example if you go through a full install (with a new apk) of an
app for one user who doesn't have it already installed, you will
still get the PACKAGED_REPLACED messages even though this is
technically the first install for your user. I'm not sure how
much of an issue this is.
When you call the existing API to uninstall an app, this toggles
the installed state of the app for that user to be off. Only if
that is the last user user that has the app uinstalled will it
actually be removed from the device. Again there is a new flag
you can pass in to force the app to be uninstalled for all users.
Also fixed issues with cleaning external storage of apps, which
was not dealing with multiple users. We now keep track of cleaning
each user for each package.

Created base tracker that handles common bookkeeping, and move VPN
to become a tracker. VPN status is now reflected in NetworkInfo, and
is mapped to LegacyVpnInfo.
Legacy VPN now "babysits" any init services it starts, watching for
when they stop unexpectedly.

Previous to this change the WindowManager was notifying the
BatteryDtatsService about windows that keep the screen on. WM used a
custom WakeLock tag to indicate to PowerManagerService that it had
already notified the BatteryStatsService.
This change eliminates WindowManager notifying the BatteryStatsService
and lets PowerManagerService do the job.
Fixes bug 7030326.

Remove the last user of FileUtils#getFileStatus and move it to

equivalent of a stat.

PackageManagerService just needed to know the owner for this file, so
just use stat instead so we can remove the old JNI code.
This is the last user of FileUtils#getPermissions so just remove the

Emulated external storage always has multi-user support using paths
like "/data/media/<user_id>". Creates and destroys these paths along
with user data. Uses new ensure_dir() to create directories while
always ensuring permissions.
Add external storage mount mode to zygote, supporting both single-
and multi-user devices. For example, devices with physical SD cards
are treated as single-user. Begin migrating to mount mode instead
of relying on sdcard_r GID to enforce READ_EXTERNAL_STORAGE.

The major goal of this rewrite is to make it easier to implement
power management policies correctly. According, the new
implementation primarily uses state-based rather than event-based
triggers for applying changes to the current power state.
For example, when an application requests that the proximity
sensor be used to manage the screen state (by way of a wake lock),
the power manager makes note of the fact that the set of
wake locks changed. Then it executes a common update function
that recalculates the entire state, first looking at wake locks,
then considering user activity, and eventually determining whether
the screen should be turned on or off. At this point it may
make a request to a component called the DisplayPowerController
to asynchronously update the display's powe state. Likewise,
DisplayPowerController makes note of the updated power request
and schedules its own update function to figure out what needs
to be changed.
The big benefit of this approach is that it's easy to mutate
multiple properties of the power state simultaneously then
apply their joint effects together all at once. Transitions
between states are detected and resolved by the update in
a consistent manner.
The new power manager service has is implemented as a set of
loosely coupled components. For the most part, information
only flows one way through these components (by issuing a
request to that component) although some components support
sending a message back to indicate when the work has been
completed. For example, the DisplayPowerController posts
a callback runnable asynchronously to tell the PowerManagerService
when the display is ready. An important feature of this
approach is that each component neatly encapsulates its
state and maintains its own invariants. Moreover, we do
not need to worry about deadlocks or awkward mutual exclusion
semantics because most of the requests are asynchronous.
The benefits of this design are especially apparent in
the implementation of the screen on / off and brightness
control animations which are able to take advantage of
framework features like properties, ObjectAnimator
and Choreographer.
The screen on / off animation is now the responsibility
of the power manager (instead of surface flinger). This change
makes it much easier to ensure that the animation is properly
coordinated with other power state changes and eliminates
the cause of race conditions in the older implementation.
The because of the userActivity() function has been changed
so that it never wakes the device from sleep. This change
removes ambiguity around forcing or disabling user activity
for various purposes. To wake the device, use wakeUp().
To put it to sleep, use goToSleep(). Simple.
The power manager service interface and API has been significantly
simplified and consolidated. Also fixed some inconsistencies
related to how the minimum and maximum screen brightness setting
was presented in brightness control widgets and enforced behind
the scenes.
At present the following features are implemented:
- Wake locks.
- User activity.
- Wake up / go to sleep.
- Power state broadcasts.
- Battery stats and event log notifications.
- Dreams.
- Proximity screen off.
- Animated screen on / off transitions.
- Auto-dimming.
- Auto-brightness control for the screen backlight with
different timeouts for ramping up versus ramping down.
- Auto-on when plugged or unplugged.
- Stay on when plugged.
- Device administration maximum user activity timeout.
- Application controlled brightness via window manager.
The following features are not yet implemented:
- Reduced user activity timeout for the key guard.
- Reduced user activity timeout for the phone application.
- Coordinating screen on barriers with the window manager.
- Preventing auto-rotation during power state changes.
- Auto-brightness adjustment setting (feature was disabled
in previous version of the power manager service pending
an improved UI design so leaving it out for now).
- Interpolated brightness control (a proposed new scheme
for more compactly specifying auto-brightness levels
in config.xml).
- Button / keyboard backlight control.
- Change window manager to associated WorkSource with
KEEP_SCREEN_ON_FLAG wake lock instead of talking
directly to the battery stats service.
- Optionally support animating screen brightness when
turning on/off instead of playing electron beam animation
(config_animateScreenLights).
