Log Message:
Synopsis
  ==========

 This CR is for switching using MDP when CQoSRateMgr has a pointer to
UberStreamManager and needs to be updated with the switch

 Branches           :  HEAD , SERVER_12_RN
 Suggested Reviewer :  Jamie

   Description
   ============
     While switching using MDP QosRateMgr has a data member which points
to UberStreamManager and after the switch occurs since the
inputsource has changed ,this reference to UberStreamManager also
needs to be changed.

  Fix
 ==========
   Create an interface IHXUberSource which has the method SwitchUberSource
where the new switched UberStreamManager is passed so that the shim
when switching passes the pointer so the the QoSRateManager can update
its Rate Manager

      Files Affected
  ================

   server\engine\core\pub\server_piids.h
   server\include\ihxubermgr.h
   server\engine\inputsource\mdpshim.cpp
   server\engine\dataflow\pub\static_pushpktflow.h
   server\engine\dataflow\static_pushpktflow.cpp
   server-restricted\qos\session\pub\qos_sess_qosratemgr.h
   server-restricted\qos\session\qos_sess_qosratemgr.cpp

   Testing Performed
  =================
Functional-Testing:
    Checked that a fcs mdp clip plays and we get no asserts when a switch
happens.

 Leak-Tests:
    dtors of objects are called and further leaks need to be tested.

Build verified  :win32-i386-vc7,sunos-5.10-sparc-server,linux-rhel4-i686
Platforms tested: win32-i386-vc7


 Thanks
