Before now, receiving a broadcast would cause a process to be hoisted
to foreground priority / cgroup. This is no longer the case: broadcasts
by default are handled in the background, with a suitably increased
timeout interval. When a given broadcast needs to be dealt with in a
more timely manner, the issuer can set the new FLAG_BROADCAST_FOREGROUND
flag on the Intent, which will produce the old foreground-priority
behavior.
To avoid priority inversions, foreground broadcasts are tracked on a
separate outgoing queue and can be in flight simultaneously with a
background-priority broadcast. If there is already a background-level
broadcast in flight to a given app and then a foreground-level one is
dispatched to that app, the app [and its handling of both broadcasts]
will be properly hoisted to foreground priority.
This change is also essentially the first step towards refactoring the
broadcast-handling portions of the Activity Manager into a more
independent existence. Making BroadcastQueue a top-level class and
regularizing its operation viz the primary Activity Manager operation
is the next step.

Because the NetworkInfo included in CONNECTIVITY_ACTION broadcast
extra does not reflect the state applicable to the calling UID, and
the last sticky broadcast may have stale state, transition to calling
ConnectivityManager.getActiveNetworkInfo() directly.

Split existing network stats into two separate classes: a recorder
which generates historical data based on periodic counter snapshots,
and a collection of historical data with persistance logic.
Recorder keeps a pending history in memory until outstanding data
crosses a specific threshold. Persisting is handled through a given
FileRotator. This pattern significantly reduces disk churn and
memory overhead. Separate UID data from UID tag data, enabling a
shorter rotation cycle. Migrate existing stats into new structure.
Remove "xt" stats until iptables hooks are ready. Avoid consuming
Entry values when recording into NetworkStatsHistory. Assign
operation counts to default route interface.
Introduce "Rewriter" interface in FileRotator with methods to enable
rewriteAll(). Introduce IndentingPrintWriter to handle indenting in
dump() methods.

1. Now when an interrogating client requires an AccessibilibtyNodeInfo
we aggressively prefetch all the predecessors of that node and its
descendants. The number of fetched nodes in one call is limited to
keep the APIs responsive. The prefetched nodes infos are cached in
the client process. The node info cache is invalidated partially or
completely based on the fired accessibility events. For example,
TYPE_WINDOW_STATE_CHANGED event clears the cache while
TYPE_VIEW_FOCUSED removed the focused node from the cache, etc.
Note that the cache is only for the currently active window.
The ViewRootImple also keeps track of only the ids of the node
infos it has sent to each querying process to avoid duplicating
work. Usually only one process will query the screen content
but we support the general case. Also all the caches are
automatically invalidated so not additional bookkeeping is
required. This simple strategy leads to 10X improving the
speed of the querying APIs.
2. The Monkey and UI test automation framework were registering a
raw event listener for accessibility events and hence perform
connection and cache management in similar way to an AccessibilityService.
This is fragile and requires the implementer to know internal framework
stuff. Now the functionality required by the Monkey and the UI automation
is encapsulated in a new UiTestAutomationBridge class. To enable this
was requited some refactoring of AccessibilityService.
3. Removed the *doSomethiong*InActiveWindow methods from the
AccessibilityInteractionClient and the AccessibilityInteractionConnection.
The function of these methods is implemented by the not *InActiveWindow
version while passing appropriate constants.
4. Updated the internal window Querying tests to use the new
UiTestAutomationBridge.
5. If the ViewRootImple was not initialized the querying APIs of
the IAccessibilityInteractionConnection implementation were
returning immediately without calling the callback with null.
This was causing the client side to wait until it times out. Now
the client is notified as soon as the call fails.
6. Added a check to guarantee that Views with AccessibilityNodeProvider
do not have children.

This is between the two previous attempts. I returned the part from the
original that was breaking gallery, but have some new code to detect when
something about the window params has changed that would require a
layout pass to make sure we still do a layout then, even if the window is
not currently visible.

The special shared-storage step was mistakenly writing its data directly
to the USB output pipe rather than to the proper stacked data handling
chain that applies compression and encryption. Fix this by getting rid
of the custom handling of the shared-storage data, instead folding it
into the normal data handling flow [with a small amount of additional
management because e.g. it doesn't need a "manifest" pseudofile in the
archive stream].

Don't consider a window as a candidate for the top fullscreen window
if it is not going to be a candiate for layout.
This fix does not include the change to ignore app tokens that are
hidden. This causes problems in some dialogs that stay hidden until
their app is ready to display, but need to perform a series of relayouts
during that time to get to the right size. Dropping this part of
the change still (mostly?) seems to allow us to avoid the bad states.

Plug a couple of apparent code paths (one not obviously reachable, but
fixed here on general principles) that could lead to a backup pass
getting confused partway through and simply never properly completing.
In this state it would leave its wakelock held forever until next
reboot. Bug 5828859.
Those fixes are a total of two lines of code. The rest of the patch
adds a textual journal of the most recently completed (or ongoing!)
backup pass's progress, with an eye to being able to isolate any such
issues that may crop up in the future.

This fixes a bug where the device fails to lock when DevicePolicyManagerService
requests the device to be locked and the screen was off because the user hit
the power button.
The change allows DPMS to directly invoke screen lock, bypasssing the screen state.

Currently test harnesses depends on this flag to determine when
the system is fully booted, and start dismissing keyguard, launch
tests etc. However, the flag is usually set when the boot animation
is still running, and typically about 5 seconds before keyguard is
up etc. Moving to to when BOOT_COMPLETE broadcast is sent makes it
work more reliable.
We also discussed about using sys.boot_completed instead,
unfortunately this flag is not in all platform and we still have
backwards compatibility to maintain in order to drive unbundled
tests.

In particular, don't do O(asec_apps * installed_apps) work during the
broadcast receiver's operation. On devices with many installed apps
and a large number of them moved to ASECs, this was causing the system
process to become unresponsive and the watchdog to fire -- which in turn
would initiate a restart loop, as the same package-installed broadcast
would then be issued again once the package manager rescanned the ASEC
containers, ad infinitum. With this change, the expensive call to the
package manager is only made once rather than asec_apps times.

Fix 5783857: Device Policy Manager doesn't allow Face Unlock
This makes it so that if face unlock is enabled and then a device policy
manager that requires something more secure than face unlock is installed,
the user will be forced to choose a new acceptable lock type.
This was previously fixed for the case where the device had been reset, or
the shell was restarted after setting face unlock, but not for the case where the
device remained on between setting face unlock and setting up a device policy
manager.
Also changed the function ordering of saveLockPattern() so that the overloaded
wrapper function is next to the main function.
