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.

Speed up orientation rotation
services: don't clear wallpaper when SystemUI
disconnects.

When we restart SystemUI (or the user), sometimes
the wallpaper would get cleared. This patch just
captures its originating component and
if that is our SystemUI component, ignore the event.

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.

Fixed by properly setting mAccounts object if it is null prior
to use after function onCreate has been called.

frameworks/base: move the traces file to avoid data loss.

If an ANR comes just after the framework reboot, the traces for
the framework reboot will get over-written with the ANR traces.
So, We are missing the traces for the framework reboot which
makes debugging the framework reboot difficult.

This patch will rename this trace file for the framework reboot
once the ActivityManager collects the traces.

frameworks/base: creating sperate files for ANRs traces

If an ANR comes just after the framework reboot, the traces for the
framework reboot will get over-written with the ANR traces. So, We
are missing the traces for the framework reboot which makes debugging
the framework reboot difficult.

Even for multiple ANRs in different apps, we will get the traces for
the last ANR.

Most of the time traces show that the call is stuck in some native call
and we do not have any info about the native call stack becuase we do
not collect the tombstones for teh ANR.

This patch will create one trace file for each application in case of ANR
and the filename would be traces_<app_name>.txt and the traces for
framework reboot will be stored in traces.txt
