Building NetEqEventLogInput requires protobuf support, while building NetEqRtpDumpInput located in the same file does not. This makes both classes unusable when protobuf support is lacking. With this CL, the NetEqEventLogInput is broken out into separate files, to allow usage of NetEqRtpDumpInput even when protobufs are not supported.
