Improve scrolling cache

Scrolling cache helps make short scrolls/flings smooth but will
cause stutter when long flings are made. This patch disables
scrolling cache when long flings are made.

This patch also fixes a related bug where scrolling cache will
not be enabled properly when transitioning from flinging to scrolling.

Patch Set 2: Calculate threshold based on maximum velocity (Sang Tae Park)

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.

Change default intent

Older JB releases have a bug handling persistence invocation. One work
around right now is to have the newer release (with persistence)
use  a lower intent value to allow older release to operate in group
owner mode.

Function uri.getAuthority is called twice. Minor doc corrections.

Function uri.getAuthority was called twice in methods acquireProvider
and acquireExistingProvider was called twice although a parameter
representing the value had existed. The second call to the function is
changed to the parameter. The parameter's modifier changed to final.
Minor corrections in function descriptions in the file.
