Frameworks: add abillity to use quick settings pulldown on the left side

This commit gives the ability to use quick settings pulldown on the left
or right edge of the statusbar. As well this respects still RTL layouts
where it logically should change to the oposite side.

ANR caused by incorrect cleanup in BroadcastQueue.

Two broadcasts could be sent to the same app simultaneously:
one foreground, one background. For example, LOCALE_CHANGED
and PACKAGE_CHANGED are delievered to com.android.vending
at the same time.
1. AMS started new vending process to handle LOCALE_CHANGED.
   And set app.curReceiver = LOCALE_CHANGED.
2. Before LOCALE_CHANGED is handled by vending process,
   PACKAGE_CHANGED was delievered to vending process too.
   AMS set app.curReceiver = PACKAGE_CHANGED. Bad!
3. Vending process finished handling LOCALE_CHANGED.
   AMS clear app.curReceiver = NULL. Bad!
   And Vending process  killed itself without handling
   PACKAGE_CHANGED.
4. AMS known vending process has died, but didn't know that
   BgBroadcastQueue was still waiting for finish message
   for PACKAGE_CHANGED.
At last, BgBroadcastQueue reported ANR for PACKAGE_CHANGED.

This patch adds protection before clearing app.curReceiver,
only set to NULL if the finishing receiver = app.curReceiver
So handleAppDied would know that PACKAGE_CHANGED was not
finished yet, it will abort the broadcast and continue.

Fix Presentation window is removed on stack change

If an activity show a Presentation window and this activity is moved
to bottom or top, thus this Presentation window will be removed from
its display window list, and no chance to be added back into window
container; It will cause the incorrect state that Presentation window
is lost from secondary display window list(displayContent.mWindows),
but still exist in app token's window list(appWindowToken.allAppWindows);
Moreover, once this activity resume again, Presentation window is not
shown because it's lost.

In this way, don't remove non-target display app windows due to only
target(or called default) display windows are removed temporarily and
re-sorted then added back into window list later.

Sync focus stack frame and layer with focus app.

Update focus stack frame/layer when focus app is changed to avoid
focus stack/layer isn't updated synchronously with focus app, it's
due to performLayoutAndPlaceSurfacesLocked() is not necessarily
called on focus app change; it will cause sending mismatching
TAP_OUTSIDE_STACK message if there is effectual incoming pointer
event, hence may also result in focus stack is changed again,
therefore erroneous focus app is set by ActivityManager at final.

Not include fullscreen opaque window on screenshot

Extend the fullscreen meaning by adding opaque drawn check on
screenshot application; if there is a fullscreen window but not
opaque, we will continue finding behind windows; otherwise ending up
including behind windows. It's able to help avoiding capturing BLACK
screenshot bitmap.

Measure absolute value of pointer motion distance

If pointer is moving to the negative axis direction, pointer movement
distance will always less than pre-defined mMotionSlop, thus
TAP_OUTSIDE_STACK will have chance to be sent, will cause unnecessary
focus stack switch.

Start MountService before performBootDexOpt

This change is to start Mountservice before starting
performBootDexOpt, as in one case, in performBootDexOpt
when system upgrade happens, StorageManager will be started to
get the low threshold of DataDir. But, at this point, as
Mountservice is still not up, StorageManager will end up
having a null object of Mountservice.

Add window to child window list with correct order

The original logic of comparing with mBaseLayer of two child windows
of the same parent was wrong, because the mBaseLayer is always the
same.

After adding two child windows with the same positive sublayer, the
one added later should have greater z-order. The order should be
consistent with WindowManagerService.addAttachedWindowToListLocked()

pm: Add persist property to enable lazy dexopt

 * Add "persist.sys.lazy.dexopt" property to enable lazy dexopt
   on userdebug builds.  As much as I enjoy these 20 minute
   dexopt sessions, I prefer instant gratification.

Frameworks: Do not show privacy guard notification on lockscreen

Does not really makes sense to notify on lockscreen that the background app is
privacy guard protected. Notification in statusbar is more then enough.

Solve it with simply tagging the notification and check against the TAG
