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.

Previously, this flag conflicted with other text direction flags,
which can cause weird interactions across the View hierarchy,
specifically with ListView.
Also adds dumpFlags() utility to dump values of all know flags for
documentation and sanity checking.

Activity manager now updates window manager's current user id
directly and immediately rather than waiting for a broadcast
update. Window manager passes this through policy to the
KeyguardViewMediator and into LockPatternUtils. LockPatternUtils
no longer goes to Activity to get the current user id if it finds
that its local id is non-default.
Fixes bug 7193726.

Launcher occasionally crashes with a stack trace indicating that the memory
of a Layer object is corrupt. It is possible for us to delete a Layer
structure and then, briefly, use it to draw a DisplayList again before
that DisplayList gets recreated (without the layer that got deleted).
When this happens, if the memory got corrupted, it's possible to crash.
The fix is to add Layer to the other objects which we currently refcount
(bitmaps, shaders, etc.). Then instead of deleting a Layer, we decrement the
refcount. We increment when creating it, then increment it again when it's
referenced from a DisplayList. Then we decrement the refcount instead of
deleting it, and decrement when we clear a DisplayList that refers to it.
Then when the refcount reaches 0, we delete it.

Take touch point size into account during the detection of scaling
gestures. Average together the major/minor axes of the size.
Add a config resource for tuning the minimum span requred to begin
(or end) a scale. This may be altered in a device-specific overlay
for devices that deviate too far from their assigned density bucket.

1. Currently the system fires accessibility events to announce the
start and end of a touch exploration gesture. However, such a
gesture starts after we have decided that the user is not
performing a gesture which is achieved by measuring speed of
movement during a threshold distance. This allows an accessibility
service to provide some feedback to the user so he knows that
he is touch exploring.
This change adds event types for the first and last touches
of the user. Note that the first touch does not conincide with
the start of a touch exploration gesture since we need a time
or distance to pass before we know whether the user explores
or gestures. However, it is very useful for an accessibility
service to know when the user starts to interact with the
touch screen so it can turn the speech off, to name one
compelling use case.
This change also provides event types for the start and end
of gesture detection. If the user has moved over the threshold
with a speed greater than X, then the system detects gestures.
It is useful for an accessibility service to know the begin
and end of gesture detection so it can provide given feedback
type for such a gesture, say it may produce haptic feedback
or sound that differs for the one for touch exploration.
The main benefit of announcing these new events is that an
accessibility service can provide feedback for each touch
state allowing the user to always know what he is doing.

1. For accessibility purposes it is important to be able to associate
a view with content with a view that labels it. For example, if
an accessibility service knows that a TextView is associated with
an EditText, it can provide much richer feedback.
This change adds APIs for setting a view to be the label for another
one and setting the label for a view, i.e. the reverse association.
