Rather than normal Activities (which have a host of problems
when used for this purpose), screen savers are now a
special kind of Service that can add views to its own
special window (TYPE_DREAM, in the SCREENSAVER layer).
Dreams are now launched by the power manager; whenever it is
about to turn the screen off, it asks the window manager if
it wants to run a screen saver instead. (http://b/5677408)
Also, the new config_enableDreams bool allows the entire
feature to be switched on or off in one place. It is
currently switched off (and the APIs are all @hidden).

Extracted the input system from the window manager service into
a new input manager service. This will make it easier to
offer new input-related features to applications.
Cleaned up the input manager service JNI layer somewhat to get rid
of all of the unnecessary checks for whether the input manager
had been initialized. Simplified the callback layer as well.

Move all lockscreen related settings to LockSettingsService.
LockPatternUtils uses this through IPC instead of Secure settings.
Migrate old settings to new database managed by LockSettingsService.
Passwords and patterns are stored in a new per-user location, except
for the primary user, for backward compatibility.
KeyguardViewMediator and LockPatternKeyguardView listen for changes
to user and updates the lockscreen.
Settings provider will look for Lock settings in the LockSettings
service now for the entries that used to be stored in Settings.

An "UpdateLock" works similarly to a wake lock in API: the caller is
providing a hint to the OS that now is not a good time to interrupt
the user/device in order to do intrusive work like applying OTAs.
This is particularly important for headless or kiosk-like products
where ordinarily the update process will be automatically scheduled
and proceed without user or administrator intervention.
UpdateLocks require that the caller hold the new signatureOrSystem
permission android.permission.UPDATE_LOCK. acquire() and release()
will throw security exceptions if this is not the case.
The "is now convenient?" state is expressed to interested parties
by way of a sticky broadcast sent only to registered listeners. The
broadcast is protected; only the system can send it, so listeners
can trust it to be accurate. The broadcast intent also includes a
timestamp (System.currentTimeMillis()) to help inform listeners that
wish to implement scheduling policies based on when the device became
idle.
The API change here is a tiny one: a dump(PrintWriter) method has been
added to the TokenWatcher class to facilitate getting information out
of it for dumpsys purposes. UpdateLock itself is still @hide.

Add a small service to the high level core set of system services to
control the configuration of the native common time service. This
service is responsible for controlling policy regarding when the
common time service should be allowed to run, which networks it is
allowed to run on, what priority it runs at in the master election
algorithm, and so on.

SerialManager: provides access to serial ports
SerialPort: for reading and writing data to and from serial ports
IO with both array based and direct ByteBuffers is supported.
Accessing serial ports requires android.permission.SERIAL_PORT permission
Each platform must configure list of supported serial ports in the
config_serialPorts resource overlay
(this is needed to prevent apps from accidentally accessing the bluetooth
or other system UARTs).
In addition, the platform uevent.rc file must set the owner to the
/dev/tty* files to "system" so the framework can access the port.

EntropyService implies that this program provides entropy to other
programs, and is misleading. The EntropyMixer class is designed purely
to stir the existing entropy pool with some possibily random-ish data,
and carryover entropy across device reboots.

...the "Complete action using" dialog
When an application goes idle, it sends back to the activity manager
the configuration it last used, to make sure the two don't get out
of sync. Fix a bunch of edge cases here in dealing with that, and
be sure to also send the current configuration when launching an
activity so the client is always up-to-date when launching.
Also a small fix to not show the upgrading dialog during first boot.

Watch for network statistics to cross NetworkPolicy warning or limit,
and show notifications to user as needed. Currently checks during

Instead of deriving network identity based on raw subsystem broadcasts,
listen for updates from ConnectivityService. Added atomic view of all
active NetworkState, and build map from "iface" to NetworkIdentity set

general templates. Added TelephonyManager mapping to classify network
types using broad labels like "3G" or "4G", used to drive templates.

Periodically records delta network traffic into historical buckets to
support other services, such NetworkPolicyManager and Settings UI.
Introduces NetworkStatsHistory structure which contains sparse, uniform
buckets of data usage defined by timestamps. Service periodically
polls NetworkStats and records changes into buckets. It only persists
to disk when substantial changes have occured. Current parameters
create 4 buckets each day, and persist for 90 days, resulting in about
8kB of data per network.
Only records stats for "well known" network interfaces that have been
claimed by Telephony or Wi-Fi subsystems. Historical stats are also
keyed off identity (such as IMSI) to support SIM swapping.

Teach ConnectivityManager about UID-specific rules derived from policy,
such as rejecting network traffic on "paid" interfaces. Calls that
return NetworkInfo now filter based on any REJECT rules in effect for
the calling UID. (Added uid parameter if callers that still want all
interfaces.)
Changed NetworkPolicyManager to derive rules based on current policy
combined with PowerManager and ActivityManager status, which it passes
to ConnectivityService for eventual enforcement through netd. When
rules change the usability of a NetworkInfo for a specific UID, it also
dispatches CONNECTIVITY_ACTION broadcasts to that UID. Combined paid
and background policy together to match current working definition.
Change-Id: I797ea49439fcc487cfe2cbc16703d4b91ceb9af6
The POLICY_REJECT_BACKGROUND policy requires that network traffic be
blocked when a UID goes into the background. Even if the UID has an
activity in the foreground, it's considered "background" if the screen
is turned off.
This changes watches for SCREEN_ON/OFF broadcasts, and rule generation
now observes screen state. It also introduces an observer pattern so
that ActivityManager doesn't directly know about NetworkPolicy, and
moves the service management into SystemServer.

When a USB device or accessory is connected, the UsbService now asks the
user which application to associate with the device or accessory.
Applications interested in devices or accessories must specify the
devices they work with via meta-data attached to their manifest.
Permission to communicate with the device is assigned when the user chooses
the activity to use for the device.
The user has the option of clicking the "always use this application" checkbox
to make the assignment automatic in the future.
The user may later clear this preference and revoke permission for an application
to have permission to communicate with the device by clicking the "Clear defaults"
button for the activity in the Manage Applications panel in Settings.
Added class UsbResolveActivity (a subclass or ResolveActivity for choosing
an activity for a USB device or accessory)
Added UsbDeviceManager, which manages the mapping between USB devices/accessories
and applications, including default applications for devices and accessories,
and manages application permissions.
Add interface to allow Settings to clear device and accessory
preferences and permissions for an application.
Remove obsolete ACCESS_USB permission.
Add new signatureOrSystem MANAGE_USB permission to allow administrating

- The ImageWallpaper wasn't watching for the desired dimensions to
change, at which point it needs to resize its surface.
- The system process has been running with the small dalvik heap
limit, which is too tight with these huge wallpapers; this would
cause switching wallpapers to eventually stop working as it
couldn't get the memory it needed to load the new one.
- The compatibility mode background surface had a bunch of issues,
such as moving its windows to the right by the window size to
make them disappear. This of course doesn't play well with the
now super-sized wallpaper surface. This code is re-worked to
not require such shenanigans.
