brandtr 0aabdac743 Generalize UlpfecPacketGenerator into AugmentedPacketGenerator.
Main changes:
- Split out general functionality from UlpfecPacketGenerator
  into a new class AugmentedPacketGenerator. This will allow
  for the addition of a FlexfecPacketGenerator that inherits
  from AugmentedPacketGenerator.
- Rename RawRtpPacket to AugmentedPacket. This name is more
  reflective of its purpose, i.e., an FEC packet with an
  additional WebRtcRTPHeader.
- Return std::unique_ptr's instead of raw pointers.

Minor changes:
- Update names, based on RawRtpPacket -> AugmentedPacket name
  change, in FEC unit tests.
- Rename |generator_| to |packet_generator_|, in FEC unit tests.
- Change some int's to size_t's in the packet generator classes.
- Use std::unique_ptr in ProducerFec unittest.

No functionality or performance changes are expected
due to this CL.
