There are two things going on here:
(1) In secondary users, some times theme information such as whether
the window is full screen opaque was not being retrieved, so the window
manager didn't know that it could hide the windows behind the app.
This would just be a performance problem, except that:
(2) There appear to be a number of applications that declare that they
are full screen opaque, when in fact they are not. Instead they are
using window surfaces with an alpha channel, and setting some pixels
in their window to a non-opaque alpha level. This will allow you to
see whatever is behind the app. If the system happens to completely
remove the windows behind the app, and somebody is filling the frame
buffer with black, then you will see what the app intends -- those
parts of its UI blended with black. If one of those cases doesn't
hold (and though we have never guaranteed they would, in practice this
is generally what happens), then you will see something else.
At any rate, if nothing else than for performance reasons, we need to
fix issue #1.
It turns out what is happening here is that the AttributeCache used
by the activity manager and window manager to retreive theme and other
information about applications has not yet been updated for multi-user.
One of the things we retrieve from this is the theme information telling
the window manager whether an application's window should be treated
as full screen opaque, allowing it to hide any windows behind it. In
the current implementation, the AttributeCache always retrieves this
information about the application as the primary user (user 0).
So, if you have an application that is installed on a secondary user but
not installed on the primary user, when the AttributeCache tries to retrieve
the requested information for it, then from the perspective of the primary user
it considers the application not installed, and is not able to retrieve that
info.
The change here makes AttributeCache multi-user aware, keeping all of its
data separately per-user, and requiring that callers now provide the user
they want to retrieve information for. Activity manager and window manager
are updated to be able to pass in the user when needed. This required some
fiddling of the window manager to have that information available -- in
particular it needs to be associated with the AppWindowToken.

Bug: 7660973
RemoteViewsAdapter will now store the userId as part of the cache key
when caching remote views to optimize for orientation changes.

This was initially about the Clock widget crashing repeatedly on some
devices with multiple users. Turned out that there were race conditions
when switching users that could result in remote views of one user calling
back to the RemoteViewsAdapter in keyguard that in turn sent an incorrect widget id
to a different user's widget, resulting in a crash.
Since KeyguardHostView is instantiated in the same process for different users,
it needs to carry a user identity to pass along to AppWidgetService so that
remote views services were bound to the correct user and callbacks were attached and
detached properly.
Added some aidl calls that take the userId to do the binding properly. A more
complete fix might be needed in the future so that all calls from Keyguard carry
the user id.
Also, there was a problem in comparing host uid for secondary users, since Settings
for a secondary user has a different uid than keyguard. Not an issue on single-user
systems. Changed the host.uid comparison to accomodate for the secondary user.

- remove unnecessary calls to resetRtlProperties().
- now reset of RTL properties will only be done when adding a View
(and no more when removing it)

getChar(String) and getChar(String, char) had wrong description in their
javadoc.
Also most of the get methods with default value were missing the corresponding
@param tag for the default value parameter.

AudioService relies on a valid mmc in order to enforce the headset
volume limitation or not. There is a timeout to enforce the limitation
if no mcc is configured after boot.
Until this timeout is reached or a valid SIM is detected the headset
volume is not limited.
This change makes that the last known volume limitation state (enforced or
not) is persisted so that next time we boot, last known state is applied until
a new mcc is configured if any. In most cases, the mcc does not change from one
boot to the next and we do the right thing. If teh mcc does change, the correct
policy will be enforced when the mcc is detected or after the timeout.
Also fix a bug where the volume panel was not displayed if the limitation mechanism
is triggered at the first press on VOL+ key.

This does some cleanup of the initial boot, especially when
booting in "no core apps" mode for encryption/decryption.
