I see this is moved from webrtc/voice_engine/test/auto_test/voe_standard_test.h
but why is not gflags replaced with the rtc_base flags.h?

This is not a target based on test_main, I just wanted to fix the usage of
gflags when I ran into it. But it's irrelevant in this CL, will be changed in
the following one. I reverted these files now.

 class TestRtpObserver : public webrtc::VoERTPObserver {
  public:
   TestRtpObserver() : changed_ssrc_event_(webrtc::EventWrapper::Create()) {}
