    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.

    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.

ActivityManagerService: stay away from zombie content providers

When the lowmemorykiller kills a content provider in an unfortunate
moment, an innocent client app can become attached to a zombie provider
and be unconditionally killed moments after, when the dead provider is
being removed.
Prevent this race by addition of isAlive function to Process.java that
determines whether a process is still running and is not only a zombie,
add a check of the state of the provider process to getContentProviderImpl.

Ensure running mTouchModeReset when AbsListView is detached

mTouchModeReset should be executed when AbsListView is detached from window.
If not, when the AbsListView is re-attaced to window,
the child can retain a pressed state.

You can see this problem easily when you double-touch an item of
option menu very quickly.

Fix ListView is not scrolled properly with arrows

According to ListView's layoutChildren logic, it detaches all children
and rebuilds its children based on visible area which might omit
invisible elements in the adapter.

In this case, arrowScroll methods only tries to find next scroll
candidates from its children so user is unable to scroll more with
D-pad.

This fixes the issue by look forward next child among the adapter as
well as children.

Scroll: modified velocitytracker

Velocitytracker and overscroll are called on every touch event to
calculate if there is a scrolling/fling. Move this and the recycling
to static voids so they are pre-optimized at compile time rather than
after evoking the method call during runtime (JIT) to increase responsiveness.

Fix for ambiguous and broken disk formatting dialog

This patch ensures that the path-string from StorageNotification is converted
to the appropriate StorageVolume so that it can be correctly passed to the
formatting class. It also displays this path to the user so that it is clear
what will be deleted.

While trying to use a USB flash drive over OTG, the drive's FS somehow got
corrupted, so Android gave me a notification to re-format it. Okay, so then
a dialog pops up that doesn't specify what volume/device it will format, and
I incorrectly assumed it would be the USb drive. However this activity defaults
to the main internal memory for some reason, and wiped my data. Thank God for
them internets... (Dropbox)
