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.
