Fix starting window memory leak

If starting window is added to arrays like mViews in
WindowManagerImpl.java, but not accepted by WindowManagerService,
we leak starting windows. To avoid leaking, remove the view
from WindowManager.

Fix autorotation sensor loop being reactivated even when off

The sensor loop was reactivated even if turned off after a wake up
=> consider it disabled also if !mEnabled
+ turn debug mode on in case there's another issue.

Since the current autorotation sensor loop is generating 3-4% cpu eating,
we really need a way to turn it off for good for the moment.
System_server now seems to stay at 0.0% cpu with this change & autorotation off on TF101

Fix unexpected rotation change when re-enabling auto-rotate

getProposedRotation() method returns old value when re-enabling
auto-rotate option. So you can see unexpected rotation change
with the following steps.

settings -> display -> enable auto-rotate
-> rotate device to landscape -> disable auto-rotate
-> rotate device to portrait -> enable auto-rotate

This patch makes mSensorEventListener reset before it is registered again.
