henrik.lundin e8a77e3309 Refactor neteq_rtpplay
This change is a major refactoring of the neteq_rtpplay tool. It
consists of the following parts:

- NetEqTest class: Breaks out the main simulation loop from
  neteq_rtpplay into a separate class with well defined inputs and
  outputs.
- NetEqInput: Interface class for the input to NetEqTest.
- NetEqPacketSourceInput: Implementation of NetEqInput that provides a
  PacketSource objects with a NetEqInput interface. This has two
  subclasses; one for RtpFileSource and one for RtcEventLogSource.
- NetEqReplacementInput: An object that modifies the packets provided by
  another NetEqInput object, and replaces the packet payloads with meta
  data readable by a FakeDecodeFromFile decoder.
- FakeDecodeFromFile: An AudioDecoder implementation that produces
  "decoded" data by reading from an audio file.
