Squah of 30 commits fixing bugs, deadlocks, memory leaks etc

Fixed a leaked partial wakelock in AbstractThreadedSyncAdapter.

This fix ensures that onFinished() is always called in a syncClient
even if the application lacks the READ_SYNC_SETTINGS permission.

Fix infinite recursive loop

There is an apparent recursive loop at IntProperty.java
in method set(Object, Integer)

This method unconditionally invokes itself. This would seem
to indicate an infinite recursive loop that will result in a stack overflow.

This was brought over from out original JB branch.  Somehow, this got
overlooked, and never made it into JB42.

Avoid unnecessary FindClass("java/lang/String").

Use previously retrieved global reference instead.
Check for NULL after creating the global reference.

Fix deadlock of WebViewCoreThread

There was a deadlock in destroy process.
Investigation showed that WebViewCoreThread is waiting some
callbacks but in this case WebViewCoreThread can not resume
itself not to call notify method.

Flow:
1. CallbackProxy.sendMessageToUiThreadSync
2. WebViewClassic.destroy()
3. CallbackProxy.blockMessages()
4. CallbackProxy.handleMessage is called via MainThread
5. The WebViewCoreThread deadlock is occured.

The cases we have to call notify method are followings.
OVERRIDE_URL
CREATE_WINDOW
SAVE_PASSWORD
NOTIFY
OPEN_FILE_CHOOSER
JS_ALERT
JS_CONFIRM
JS_PROMPT
JS_UNLOAD
JS_TIMEOUT

FastScroller: Fix to use appropriate index

Fix FastScroller to use appropriate index to determine the
the position of a section while calculating the y coordinates
of thumb. In case of last section, use totalItemCount to determine
next section position.

Prevent MediaScanner infinite loop with invalid path

including double slash  "/storage/sdcard0/xx//xxx/xxxx"

Consider mScrollX when drawing the checkMarkDrawable

When mScrollX has a very large value the checkmark will not show,
unless it is considered when setting the bounds of the drawable.

frameworks/base: Fix for the race in Wallpaperservice

Wallpaperservice has a race among message handler of
DO_DETACH and service's onDestroy. In certain cases,
the engine kept track in mActiveEngines is removed by
message handler of DO_DETACH and service's onDestroy
doesn't get a entry in mActivieEngines and isn't able
to invoke detach. This keeps the broadcast receiver,
mReceiver active and is unregistered by the framework
and a corresponding leak is reported.

  Later, the message handler of DO_DETACH continues
and invokes detach on mEngine, which attempts to
unregister mReceiver and framework throws an exception
"Receiver not registered: android.service.wallpaper.
WallpaperService$Engine$1@40874580" and causes the
framework to reboot.

  In case of system_server, WindownManagerPolicy and
android.server.ServerThread contest for access of
shared members, mActiveEngines and mEgine. Fix is to
protect the critical section via synchronized block.

Memory leak in IInputMethodSessionWrapper executeMessage

In some cases the executeMessage is called with
mInputMethodSession == null. For the messages

memory is leaked. This commit recycles the args freeing

Fix WebView.loadData ignores encoding on Android 3.x and after

In WebView.loadData encoding parameter was ignored (expect if the value was 'base64').
Now, charset encoding is used to display the data.

The following call should display well.
webView.loadData("éàçèù", "text/plain", "utf-8") will display 'éàçèù' where it display garbage in version > 3.x.
webview.loadData("aGVsb68=", "text/plain", "base64") will still display 'hello'.
webview.loadData("6eDn6Pk=", "text/plain", "utf-8,base64") will show 'éàçèù' where it display garbage in the current version.
webview.loadDataWithBaseURL(url, "éàçèù", "text/plain", "utf-8", null) will still display 'éàçèù' if (url is null or different of "data:").
webView.loadDataWithBaseURL("data:", "éàçèù", "text/plain", "utf-8", null) will display 'éàçèù' where it display garbage in version > 3.x

This assure downward compatibility with the change made in 3.x

This fix a bug that appears in the 3.x android version.

Avoid IndexOutOfBounds Exception in ActivityManagerService

1. finishActivityLocked() doesn't give guaranty to remove only
   one ActivityRecord from the history stack.
2. Unfortunaly if our topRunningActivity is top of the stack,
   then there is potential IndexOutOfBounds Exception in
   ActivityManagerService.
To avoid it, we can just traverse to the top of the history stack.

Reduce EntropyMixer seed size from 4096 to 512 bytes.

The suggested seed size from Linux drivers/char/random.c is 512 bytes
rather than the 4096 bytes currently used.

Make EntropyMixer mix in output of Hardware RNG into Linux RNG.

On devices with Hardware RNG (HW RNG), this makes EntropyMixer
periodically (every three hours) read 512 bytes from HW RNG and mix
them into the Linux RNG.

This is done without increasing Linux RNG's entropy estimates to
avoid having to trust the quality of the HW RNG. This approach cannot
reduce the quality of the Linux RNG output, but may increase it.

Velocitytracker and overscroll are called on every touch event to

    Fixed race condition in Spinner.DialogPopup on null reference.

    NullPointerException is triggered when DialogPopup is
    dismissed due to object mPopup being null when not showing.
    Race condition is triggered when dialog is dismissed before
    touch event to dismiss dialog has been processed properly.

    Fixed by adding a null check prior to accessing mPopup object.

    [BatteryStatsImpl] Avoid memory corruption due to Parcel Recycling

    While processing batterystatsfile, in present code there is a race where a parcel
    might be recycled while it is being written to disk in another thread.

    The write process is done in 2 steps:
    - write into a Parcel (memory block)
    - then write this Parcel to disk using Journaled API.
    The Journaled API ensures robustness against file-system issues due to power cut.
    The writing is done in batch using a thread running commitPendingDataToDisk().
    This function writes the parcel to disk but this parcel is a global variable
    initialized by writeLocked(). If the writing takes too long time and two write
    threads are launched, the parcel is freed by the second writeLocked() call;
    which could cause the memory corruption.

    Hence, change global Parcel variable by a Parcel parameter to commitPendingDataToDisk()
    and only this function will be allowed to recycle the parcel.

Fix to NullPointerException when activity is relaunched

When ChooseTypeAndAccountActivity is relaunched and resumed
by ActivityManager a call is made to onActivityResult without
first triggering onResume. This leads to mAccounts object
still being null.

to use after function onCreate has been called.
