Log Message:
Synopsis
========
Fix for
Bug 210311: CA and playback stops or rebuffer and no resume about half the time \
switching from OD to live

Branches: SEREVR_12_RN , HEAD.
Suggested Reviewer: Jamie Gordon, JJ Zeng.

Description
===========
There are two problems in this bug.
1). The player rebuffers, "Communicating..."
 This is due to when we switch to live and if the first frame that is comming from \
new source is not a key frame, we are returning  error from function
 BasePacketShim::AdjustTimeStamp()
 at cndition
        if(!(pPacket->GetASMFlags() & HX_ASM_SWITCH_ON))
        {
            return NULL;
        } 
 
 So this condition is handled properly by calling GetPacket().


2). The server CAs and the playback stops
 This is happening because of function ConfigureSourceFCSSpecific() being called from \
  ClientSession::SwitchDone().
 This function should not get called for switch to live. So call restricted for only \
PPM OD. 

Files Affected
==============
/server/engine/inpusource/ppmstaticshim.cpp
/server/engine/inpusource/base_shim.cpp
/server/engine/session/clientsession.cpp

Testing Performed
=================

Unit Tests:
-None

Integration Tests:
-Some basic testing is done on windows build, no "communicating.." is observed on \
player. Let the QA come with full testing.

Leak Tests:
-None

Performance Tests:
-None

Platforms Tested: win32-i386-vc7
Build verified: win32-i386-vc7

QA Hints
===============
-This should also improve the playback quality after switch.
