Fix error checking in MemoryFile.

mmap returns MAP_FAILED on failures, not 0 (NULL).
Also, convert some C style casts to C++ since they
make intent clearer.

[ActivityManager] Reduce report ANR on wrong activity.

Symptom: ANR report on wrong activity.

Root Cause:
  KK changed resume behavior that will not update focus when only resume,
if the activity blocked, it may report ANR on previous focus.
  By original concept, it will try to correct the ANR target,
but the stack of waiting(waitingVisible=true) activity may
different with current top stack.
  If it gets key dispatch timeout, mResumedActivity and mPausingActivity
of its stack will be null becuase it is not top stack.
Then it is unable to change ANR target to the real no response activity.

Solution:
 Use focused stack to get the real culprit.

Reproduce steps:
1.Launch an Activity X from launcher, press home key.
2.Launch X from launcher again, X blocks(sleeps 15sec) in onResume, press back key in the beginning of blocking duration.
3.ANR dialog shows launcher is no response.

Google messed up again with translations.
This change is needed because it interferes with our translations
which happen to use same string names as the Keyguard test app.

audio: no notification sound when adjusting volume bar twice.

Notification sound won't take effect when the previous track hasn't
finished.
Need explicitly stop the previous ongoing track to alow the current one.

DocumentsUI: The title disappears after rotation

The onItemCheckedStateChanged() method in DirectoryFragment.java
called the setTitle() of ActionMode to modify the title of the
action bar. But this change is not redone after the activity is
recreated. Therefore, when the orientation is changed, the change
in title will be lost.

Set the android:configChanges for DocumentsActivity to avoid
recreating this activity.

UserTile: Fix displaying user information for multi-user devices

In commit 89ab0eb097322ac8eec40159b888dfb03b9413e9, we improved
the handling of single user devices but appear to have also
entirely deleted the name / avatar for multi-user devices.

This commit restores the deleted code for multi-user devices.

This fixes CYAN-4023.

Add TYPE_MAGNIFICATION_OVERLAY to InputWindowInfo::isTrustedOverlay()

This fixes a bug where a View with filterTouchesWhenObscured will have
all touches filtered when in magnification accessibility mode. This is
due to magnification being a separate Window over top of the running
Activity. The method onFilterTouchEventForSecurity in View will then
always return false when filterTouchesWhenObscured is enabled on the
View. By adding the magnification Window to the list of Trusted Overlays
we can ensure that touches will work properly with this property enabled.

Avoid SystemUI crash due to NPE

BaseStatusBar.createNotificationViews() returns null
when it reports handleNotificationError(), leading to
a forced crash of the misbehaving app. However, it
should not add a null object of Notification.Entry
since it will also crash SystemUI (crashing at compare).
