If an apptoken's removal has been delayed then it will be in both
mExitingAppTokens and the stack's tasks. When rebuilding the windows
the windows from that apptoken will get added twice. This change
skips adding those windows from apptokens that have already been
added from mExitingAppTokens.

Check explicitly for null listeners in NMS, throwing
IllegalArgumentException (on the small list of exceptions
that survive RPC boundaries) with a message.
Normally this situation is caused by listeners that attempt to
perform NM-related actions before they are bound. Check for
this case in the base NLS class and avoid the call to NM if we
know it will fail.
Although it's tempting to throw an IllegalStateException on the
client side, preserve the existing semantics for backwards-compatibility
purposes. That is, silently fail (or return null) - and provide a
log warning.

Modified ActivityView to inject touch events it receives back into
its activity container. The container then injects the event into
the input system along with the display id of the underlying virtual
display.
Enhanced the input system to support concurrent dispatch of touch
events on multiple displays which is required for this to work.

This change simplifies the process of initializing a SystemService
by folding the onCreate() step back into the constructor. It removes
some ambuiguity about what work should happen in the constructor and
should make it possible for services to retain most of their final
fields after refactoring into the new pattern.

- Remove task after removing activity. Removing the task before
removing the activity led to problems when the task was still needed.
- In WindowManager wait for activity manager to remove the task.
Previously was automatically removing the task when the last activity
was removed.

Allowing the detach of ActivityStack from DisplayContent to happen
immediately was causing all sorts of problems associated with not
having a Display to complete the animations.
Waiting for animations to complete before either the detach or the
display removal fixes those problems.

Now that activities and tasks can be detached from a display do not
keep their state within the DisplayContent class. All such state is
now moved to the TaskStack class with this change.

At startup, we check with PackageManager whether a system service is
available before attempting to load it. A system service is available
if its associated feature (similar to hardware features) is present.
This does not remove unavailable services from the compiled jar.

PendingIntents and IntentSenders can now be launched. Still does not
work once the host activity has been paused and resumed.
Window manager TaskStacks now exist independently of Displays and app
windows persist after Displays are removed below them. Attaching the
stack to a new Display does not yet restore the windows to it.

Support any number of overlay packages. Support any target package.
UPDATED PACKAGE MATCHING
------------------------
In Runtime resource overlay, iteration 1, only a single overlay package
was considered. Package matching was based on file paths:
/vendor/overlay/system/framework-res.apk corresponded to
/system/framework-res.apk. Introduce a more flexible matching scheme
where any package is an overlay package if its manifest includes
<overlay targetPackage="com.target.package"/>
For security reasons, an overlay package must fulfill certain criteria
to take effect: see below.
THE IDMAP TOOL AND IDMAP FILES
------------------------------
Idmap files are created by the 'idmap' binary; idmap files must be
present when loading packages. For the Android system, Zygote calls
'idmap' as part of the resource pre-loading. For application packages,
'idmap' is invoked via 'installd' during package installation (similar
to 'dexopt').
UPDATED FLOW
------------
The following is an outline of the start-up sequences for the Android
system and Android apps. Steps marked with '+' are introduced by this
commit.
Zygote initialization
Initial AssetManager object created
+ idmap --scan creates idmaps for overlays targeting 'android', \
stores list of overlays in /data/resource-cache/overlays.list
AssetManager caches framework-res.apk
+ AssetManager caches overlay packages listed in overlays.list
Android boot
New AssetManager's ResTable acquired
AssetManager re-uses cached framework-res.apk
+ AssetManager re-uses cached 'android' overlays (if any)
App boot
ActivityThread prepares AssetManager to load app.apk
+ ActivityThread prepares AssetManager to load app overlays (if any)
New AssetManager's ResTable acquired as per Android boot
SECURITY
--------
Overlay packages are required to be pre-loaded (in /vendor/overlay).
These packages are trusted by definition. A future iteration of runtime
resource overlay may add support for downloaded overlays, which would
likely require target and overlay signatures match for the overlay to
be trusted.
LOOKUP PRIORITY
---------------
During resource lookup, packages are sequentially queried to provide a
best match, given the constraints of the current configuration. If any
package provide a better match than what has been found so far, it
replaces the previous match. The target package is always queried last.
When loading a package with more than one overlay, the order in which
the overlays are added become significant if several packages overlay
the same resource.
Had downloaded overlays been supported, the install time could have been
used to determine the load order. Regardless, for pre-installed
overlays, the install time is randomly determined by the order in which
the Package Manager locates the packages during initial boot. To support
a well-defined order, pre-installed overlay packages are expected to
define an additional 'priority' attribute in their <overlay> tags:
<overlay targetPackage="com.target.package" priority="1234"/>
Pre-installed overlays are loaded in order of their priority attributes,
sorted in ascending order.
Assigning the same priority to several overlays targeting the same base
package leads to undefined behaviour. It is the responsibility of the
vendor to avoid this.
The following example shows the ResTable and PackageGroups after loading
an application and two overlays. The resource lookup framework will
query the packages in the order C, B, A.
+------+------+- -+------+------+
| 0x01 | | ... | | 0x7f |
+------+------+- -+------+------+
| |
"android" Target package A
|
Pre-installed overlay B (priority 1)
|
Pre-installed overlay C (priority 2)

It wasn't possible to start apps installed in /vendor/app
on a device where /vendor was a symbolic link to /system/vendor.
This is currently the default configuration for android (see
init.rc)
During installation a dex file is created at:
/data/dalvik-cache/vendor@app@blah.blah.apk@classes.dex
But dalvik would fail to start this app with the following error:
I/dalvikvm( 3453): Unable to open or create cache for /system/vendor/app/blah.apk \
(/data/dalvik-cache/system@vendor@app@blah.blah.apk@classes.dex)
Note that dalvik were trying to start /system/vendor/app while the
app was installed in /vendor. There was a conflict between the
package manager and dalvik on how to interpret paths. This change
makes the package manager consistent with dalvik.
