VCM: Updating Media Opt:

1. Removed protection method specific code from SetTargetRates
2. Updated encoding rate following protection settings
3. Removing RTT max threshold from NACK, as it is not used in the receiver side.
4. Two bug fixes: FEC conversion function fix (line #133) and residual loss calculation (line #94) 
5. Removing compiler warnings
6.. Removed unused code and general clean-up.
