Adds implementation of TFRC-SP on DCCP test tree

Due to the problems in the previuos patch pointed by Gerrit Renker, I'm resending the patches.

These patches adds implementation of TFRC-SP at the receiver side, and are targeted at the DCCP branch

Patch #1: First Patch on TFRC-SP. Copy base files from TFRC Patch #2: Implement loss counting on TFRC-SP receiver Patch #3: Implement TFRC-SP calc of mean length of loss intervals accordingly to section 3 of RFC 4828
Patch #4: Adds options DROPPED PACKETS and LOSS INTERVALS to receiver Patch #5: Updating documentation accordingly

Following this patches, we'll be sending the sender side of TFRC-SP. Once this code is integrated on the branch, we can proceed adding the CCID4 code that uses this new TFRC-SP.
