Generalize FEC header formatting.

- Split out reading/writing of FEC headers to classes separate
  from ForwardErrorCorrection. This makes ForwardErrorCorrection
  oblivious to what FEC header scheme is used, and lets it focus on
  encoding/decoding the FEC payloads.
- Add unit tests for FEC header readers/writers.
- Split ForwardErrorCorrection::XorPackets into XorHeaders and
  XorPayloads and reuse these functions for both encoding and
  decoding.
- Rename AttemptRecover -> AttemptRecovery in ForwardErrorCorrection.
