1. This change converts the accessibility manager service to
maintain a state per user. When the user changes the services
for the user that is going away are disconnected, the local
accessibility managers in the processes for this user are
disabled, the state is swapped with the new user's one, and
the new user state is refreshed.
This change updates all calls into the system to use their
user specific versions when applicable. For example, regisetring
content observers, package monitors, calls into other system
services, etc.
There are some components that are shared across users such
as UI created by the system process and the SystemUI package.
Such components are managed as a global state shared across
all users and are updated accordingly on a user switch. Since
the SystemUI is running in a normal app process this change
adds hidden APIs on the local window manager to allow the
SystemUI to notify the accessibility layer that it will run
accross users.
Calls to AccessibiltyManager's isEnabled(), isTouchExplorationEnabled()
and sendAccessibilityEvent return false or a are a nop for a
background user sice he should not send accessibility events,
and should not perform touch exploration.
Update the internal accessibility tests due to changes in the
AccessibilityManager.
This change also fixes several issues that were encountered
such as calling out the accessibility manager service with a
lock held.
Removed some incorrect debugging code from the TouchExplorer
that was leading to a system crash.

FusionEngine now attaches a secondary location that has never seen
GPS data to its result. LocationFudger uses the GPS-less location so
that COARSE apps never see data from the GPS provider.
When the previous location is updated, the previous GPS-less location
is carried over if the location update was GPS-only.
Additionally, apps without FINE permission are not notified when GPS
location changes, and any attempt to use GPS_PROVIDER without FINE
permission is met by a stern SecurityException.

Views were being kicked off when RecentsTaskLoader was being started
from BaseStatusBar.toggleRecentsActivity. Then RecentTasksLoader called
RecentsPanelView.onTasksLoaded which invalidated the Adapter and loaded
the item views. All this before window manager had determined that the
Activity should be rotated and providing a new Configuration.
This fix waits for the Activity to resume before allowing the Adapter
to be invalidated.
Fixes bug 7138698.

Content observers are registered under the calling user's identity,
not under the provider host's identity (unless the caller is using
the new permissioned entry points that allow observers to be
registered for a different user's view of the data). The most important
implication of this is that when the settings provider is directly
queried, the Cursor returned to the app is wired for change notifications
based on that calling app's user.
Note that it is not possible to use query() / insert() to read/write
data for different users. All such manipulations should use the
standard get* / put* methods in Settings.*.

The code in onMeasure that attempts to accommodate changing
child boundaries (i.e. an expanding/collapsing notification)
was locking the window size to the child measurement, even
though another window was trying to seesaw it closed. We now
only activate the rubberband behavior when the size of the
children changes, not on each onMeasure().
Lots of other small fixes to the panel expansion logic, too,
including ensuring that the expanded fraction doesn't jump
to 1.0f when the panel content hasn't been laid out yet
(causing the entire screen to become dim for a second thanks
to PhoneStatusBarView.panelExpansionChanged).
This change also restores the ability of Binder clients
(such as accessibility systems) to expand and collapse the
status bar.

Add a setting to globally disable Wifi display.
Fixed a bug where the wifi display broadcast receiver
was running on the wrong thread.
Removed the wifi-display QuickSettings dialog, all functionality
has been moved to Settings.

Dream manager now fires broadcast intents when entering + exiting
dreamland (except when testing).
Power manager can now listen for dreams ending, using polling only
as a backstop.
Also:
- Bullet-proof dream-manager/dream against known failure modes
- Add new read/write dream permissions
- Refactor dream-manager to delegate work + state management into
a new DreamController class, via a handler

The way it should have been, and with the new recents enter animation
the way it must be.
Added a new method to retrieve this thumbnail, since it would be less
efficient to use the existing API (which always returns the "base"
thumbnail). Probably at some point that existing API should be tweaked
to always return the top thumbnail instead, but that is for a later time.
Also removed code that would clear the thumbnail associated with an
activity when it is resumed. I don't think there should ever be a
reason to clear a thumbnail -- it's much better to have *something*
for the task, even if it is a little out of date.

Callers with INTERACT_ACROSS_USERS_FULL permission can now observe content
for a given user's view (and can notify content uri changes targeted to a
specific user). An observer watching for UserHandle.USER_ALL will see all
notifications for the given uri across all users; similarly, a notifier
who specifies USER_ALL will broadcast the change to all observers across
all users.
The API handles both USER_ALL or USER_CURRENT, and explicitly forbids
any other "pseudouser" designations.
This CL also revs the Settings provider to notify with USER_ALL for
changes to global settings, and with only the affected user's handle
for all other changes.

Various wifi settings that are explicitly defaulted did not get their
default code properly converted to refer to the correct settings
database table.
A collection of moved-to-Global settings that had not yet been
marked @deprecated in the Secure.* namespace are now so marked.
Also updated the namespace used to refer to wifi settings from the
Wifi Service. These changes are cosmetic, but they do eliminate a
number of runtime log messages.

Oops. Stacked bugs: first, the desired user handle was not properly
being passed from the call() entry point to the database operations;
then on top of that, the client-side cache management was still
looking in the local user's cache for the data, so a request to read
a different user's settings would return the local user's instead if
that key was already known to the local user's cache.
Reads and writes of a different user's settings are now uncached,
so they're relatively much slower. They're rare, however, so this
is not something to worry about unless we encounter a real world
case where it's a significant factor.
This CL also adds a bit of cross-user settings read/write testing
to the existing provider suite. These new tests caught both the
known wrong-user-write bug and discovered the client-side cache
bug, so yay.
Finally, the existing wholesale mutual-exclusion approach would
deadlock in certain circumstances due to the fact that the
settings database creation code might have to call out to the
Package Manager while populating the bookmark/shortcut table,
and the Package Manager would then call back into the settings
provider in the course of handling that request. The synchronization
regime has been significantly tightened up now: now the database
code [which is known to deal with concurrency itself] is allowed
to cope with multiple parallel openers of the same db; this
allows the settings provider to avoid calling out to other parts
of the system even implicitly while its internal lock is held.
