Fix memory leak in nativeDecodeFileDescriptor

Fix memory leak in nativeDecodeFileDescriptor:
SkFILEStream::kCallerRetains_Ownership is used to keep
life cycle of file in Java,so fclose is not called when
destruct SkFILEStream because ownership not belong to
native here, while when file is closed in Java, close
is called instead of fclose,that means buffer allocated
by malloc in fseek, when create SkFrontBufferedStream
with this filestream, will not be freed, because this
buffer will only be freedin fclose.
To fix this issue: duplicate this fd, and use
SkFILEStream::kCallerPasses_Ownership for SkFILEStream,
means Java and native manage file life cycle separately.

AudioService: Fix monitorRotation for landscape applications

Current implmntation only sends rotation updates on orientation
changes, so does not handle direct 0<->180 or 90<->270 transitions.

Update rotation based on an OrientationEventListener instead of
Intent.ACTION_CONFIGURATION_CHANGED

Tethering: Enable NAT only when tether and upstream ifaces are different.

When enabling WIFI hostspot, chooseUpStreamInterface will choose WIFI
interface as it is still up. It will result in both tethered and upsteam
interfaces are same one. netd will reject this command and tethering
will fail this time.

This fix will not send NAT command to netd when it found these two
interfaces are same one. Later when the real upstream interface is
brought up by ConnetivityService, Tethering.java will continue the NAT
procedure.

Telephony: Avoid Infinite loop problem in Tethering

1. Whenever data is enabled we will try to establish the tethered
call (USB tethering enabled case) for 5 fixed number of retries.
After reaching maximum number of retries we are turning off the
upstream connection. whenever the CONNECTIVTY_ACTION received
(because of USB cable disconnected and then connected case or
some changes), it can try to bring up the dun/hipri PDP again.

2. There is no retry in case of data disabled case.

Tether: fix the retry issue in Tethering

Since StartUsingNetworkFeature will always return success, it's
not a good place to set retry. With this modification, the retry
will work.
