CRtcAdaptation

This class implements the RTC Adaptation related functionality as part of 

Adaptation server.This class implements an active object to route the requests

to Adaptation plugins loaded by CSsmAdaptationServer.When requests are received

from multiple clients this class queues the requests and processes them in order.

Adaptation server  handles only one request from each session and uses Cancel()

methods to cancel any of the session's requests made before.

The queueing mechanism is to handle multiple clients at a time not to handle multiple

requests from one particular clients session.
