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.
