Applications can now specify two more aspects of the restore process: whether
they need to run with their own custom Application subclass rather than being
launched in the usual restricted mode during restore, and whether it's okay for
the backup manager to kill the app process once restore has completed. The new
manifest attributes for these are, respectively, android:restoreNeedsApplication
and android:killAfterRestore.
If unspecified in the manifest, restoreNeedsApplication is false, and
killAfterRestore is true.
In order to support kill-after-restore cleanly, this change also adds a new
system-process-only interface to the Activity Manager, which will schedule a
"commit suicide" event on the target app's main thread looper.
The framework backup agents have been given the appropriate new backup
attributes as well.
* changes:
Add a synchronous stop method to TTS synth engine so that upon its destruction, if it was synthesing to a file, the latter can be deleted without still being written to. Clear the hashmap of SpeechItem to be stopped (mKillList) when the speech queue is empty.

* changes:
Launch synthesis thread at max priority to prevent hicups in playback. Return and log an error when an operation cannot be completed because the speech queue is locked longer than the timeout period. Log cleanup.
* Other changes
+ Re-assign err codes in VpnManager.
+ Add new err codes: REMOTE_PPP_HUNG_UP, PPP_NEGOTIATION_FAILED.
+ Delete the state file only if it exists (to prevent logging an
unable-to-unlink error).
+ Extend timeout to 40 seconds.
* changes:
Implement clean killing of the TTS service. If files were being synthesized to while the service was being killed, it would have left partially written files (with no header). This CL checks if the service is rendering to a file at the time the service is destroyed: if it is, it will stop the rendering and deletes the file.

Fix bug 2046705 where the output of the speech synthesizer is too low.
Split BluetoothDevice into BluetoothDevice and BluetoothAdapter.
BluetoothAdapter: Represents the local BT adapter. Operations on the local
adapter (start a scan, etc).
BluetoothDevice: Represents a remote BT device. Operations on remote devices
(pair, connect, etc).

TODO:
Javadoc
The language files for the SVOX Pico engine result in the output of
the synthesizer to be too soft, and barely audible on a phone speaker.
The change implements a low shelf filter on the output of the synthesis
and a drastic amplification. This works as intended because the
synthesized data contains too much energy in the lower frequencies that
is wasted on a phone speaker. Once filtered out, they leave room for
amplication to address the volume issue.
Packages that do not use android.permission.BACKUP_DATA will neither be backed
up nor restored. That permission is currently signature-only. In the future if
access to the backup/restore infrastructure is made available to arbitrary 3rd
party applications, the permission checks (and indeed, the permission itself)
can simply be removed.

* changes:
Fix bug 2043140. A race condition is encountered when an application invokes shutdown() on its TextToSpeech object while is has speak() requests still running. Since the TTS service destructor releases the synthesizer resources and sets the corresponding synth reference to null, an NPE was observed. The fix consists in catching NPEs whenever the sNativeSynth object is accessed, and return the matching error for the call. This change is a "low risk" version of the fix for bug 2025765i (same issue) which was reverted because it was higher risk than this CL: it affected the logic of each call to sNativeSynth. This CL only sets an error code when an NPE is fired because sNativeSynth is null.

* changes:
Fix bug 2025765. Talkback produced a null pointer exception when being enabled and disabled repeatedly due to a race condition between the onDestroy() of the service, and the use of the service itself. The error occurs when one Talkback thread initiates the destruction of the service (call to onDestroy()) when it invokes shutdown() on its TextToSpeech instance (the client of the service). At the same time, Talkback tries to say that "Accessibility" is unchecked from another thread. During onDestroy(), the reference to the TTS engine (sNativeSynth) is reset to null, which is used in the service in speakInternalOnly(), and setLanguage(). The fix consists in the addition of a static variable that signals that the service has entered onDestroy(). Once this flag is set, all method invocations on sNativeSynth will be dismissed. Note that access to the native resources used by sNativeSynth are synchronized at the native layer, therefore preventing sNativeSynth.shutdown() to interfere with a sNativeSynth.speak() call already underway.

If the new system settings value for AIRPLANE_MODE_TOGGLEABLE_RADIOS
contains RADIO_WIFI, then the user will be allowed to enable Wifi
while in airplane mode.
Turning on airplane mode will still disable Wifi, but the user will
be free to reenable it in the Settings app.
