Update of /cvsroot/server/common/util/pub

Log Message:
Synopsis
========
add lra splitting support to RBS splitting
Branches:  head, server_12_1 
Suggested Reviewer: Chytanya, Jamie 

Description
===========

1. add new files header_helper.h/cpp to server/common/util.  Implement
Is3gpMRLive(), which is used by bdstplin and server core(later).  I
also move the DumpHeader() form bcastmgr.cpp to here.  This is a
useful function that deserves its own place:->  We have multiple
implementation of it and I don't want to add another.

2. When the live feed is 3gp mr, bdstplin will not send it to legacy
receivers(indicated by config var for push, and version number for
pull).

3. Add a new packet type for RBS: rtp payload. The original rbs didn't
handle rtp time at all.  There is one timestamp field in the payload:
when the packet is rtp, it converts rtp time into delivery time and
send it.  This way we lost the delivery time.

With the new rtp payload, the transmitter will send rtp payload to new
receivers, but preserve the old behavior for legacy receivers.

File Added

serer/common/util/header_helper.cpp, pub/header_helper.h

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

Unit Tests:
None.

Integration Tests:

Verify the transmitter rejecting pull request from legacy receivers
for 3gp mr live, but accepting from new server.

Verify the transmitter doesn't push packets to receivers configed to
be legacy.

Verify the transmitter sends rtp payloads to the new receivers, and
regular payload to legacy receivers, for both pull and push splitting.

Leak Tests:
None.(will do it later).

Performance Tests:
- None

Platforms Tested: linux-rhel5-i686
Build verified: linux-rhel5-i686
