If userId doesn't change, no need to do switchuser.or it will
introduce some tweak for gps modules in quick off/on because
they need cost time in off/on.

This is a change to add args to some of the profiler related
functions, including installd commands.
Also read properties and set command line options for the runtime
profiling parameters.
Changed calls to isDexOptNeeded() to isDexOptNeededInternal(). This
needs additional arguments passed for profiles.

- Introduce a boolean extra for intent TIME_CHANGED that
specifies if the user wants a 24 hour format or not.
- Have the ActivityManagerService inform running processes
of changes to this preference.
- Add plumbing in ActivityThread to inform j.t.DateFormat

When WindowManagerService creates a new Task, it passes atoken to the
Task constructor. In this case atoken is added to mAppTokens list by
the Task constructor and then it is added manually again by calling
newTask.mAppTokens.add(atoken). As a result, the same atoken is present
in mAppTokens list twice.
When another window token is added to the list, it may be placed in
beetwen duplicated tokens and corresponding window will be hidden from
the screen by corresponding duplicated windows.
From user perspective it means that some windows will not be displayed
on the screen.
The issue is fixed by avoid adding atoken to mAppTokens list manually
when it was added already in Task constructor.

The dreams manager also manages dozing. It has a minimal footprint
so there is no real reason to disable the component (it just makes
debugging more difficult).
Improved the documentation of the config_dreamsSupported resource
to clarify exactly what it controls.

On devices using /dev/rtc instead of /dev/alarm, updating the
time-of-day clock and RTC are separate syscalls. Hence the clock and
RTC could be left in inconsistent states if two threads called
SystemClock.setCurrentTimeMillis() simultaneously.
By moving this code into AlarmManagerService, we can put a global lock
around AlarmManagerService.setTime() and prevent the race condition.
Note that access to SystemClock.setCurrentTimeMillis() is now gated by
android.permission.SET_TIME, where before it was gated by filesystem
permissions (i.e., could the process write to /dev/alarm or /dev/rtc).

Changes in this patch include
[x] Long(64-bit) is used to store native pointers in
AssetAtlasService and related classes as they can be 64-bit.
[x] Some minor changes have been done to conform with
standard JNI practice (e.g. use of jint instead of int
in JNI function prototypes)

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.

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.

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.
