Log Message:
Synopsis
========
Fix realmedia fcs bugs.
Branches:  HEAD, server12, server_12_0
Suggested Reviewer: Jamie 

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

RV mutiple frames packets have internal timestamp, and we need to
modify them for fcs just as slta does. There is a class
CRVPacketTimeOffsetHandler to do that, but I choose to copy a few
lines over because:

1. that class uses async method of HandlePacket-PacketReady to pass
packets, which will require a major change in baseshim.

2. that class is extremely inefficient unless we rewrite it.  It does
at least 4 strcasecmp for each packets.

In addition, I also add a variable to decide to switch stream. We
can't switch at any switch_off packets: we need to switch at the video
stream.  But The method I used still not work right for multi-rate 3gp
content, and I will address that later.

By the way, I couldn't bear the code in baseshim anymore, so I
refactor it a little bit.

Remaing problems:

1. Now we can switch and the player won't complain anymore. For q=1
switch the playbacks look okay, but for q=0 the player may rebuffer
    and resume playback in a few seconds.

    2. The above-mentioned 3gp multi-rate issue.
