----------------------------------------------------------

Attached new patch. Here, I have changed the order of Mover status check in SPS. With this
change, we can avoid the unnecessary instantiation and starting of SPS thread if Mover is
running. Also, avoids shutdown calls in the exception block if the thread is interrupted by
the user or admin. [~umamaheswararao], please review. Thanks!

+Note:+ I had re-based the branch code on latest trunk code, yesterday. In this patch, I have
included few EC related modifications to make the test case run according to the trunk code.
