Alessio Bazzica 6330818ec8 NetEQ RTP Play: Optionally write output audio file 
This CL makes the output audio file optional to more
quickly run neteq_rtpplay when no audio output is needed.
The CL also includes necessary adaptations because of pre-existing
dependencies (e.g., the output audio file name is used to create
the plotting script file names).

The command line arguments are retro-compatible - i.e., same behavior
when specifying the output audio file and the new flag
--output_files_base_name is not used.

This CL also includes a test script with which the retro-compatibility
has been verified.

NetEQ RTP Play tool

Testing of the command line arguments

The command line tool neteq_rtpplay can be tested by running neteq_rtpplay_test.sh, which is not use on try bots, but it can be used before submitting any CLs that may break the behavior of the command line arguments of neteq_rtpplay.

Run neteq_rtpplay_test.sh as follows from the src/ folder:

src$ ./modules/audio_coding/neteq/tools/neteq_rtpplay_test.sh  \
  out/Default/neteq_rtpplay  \
  resources/audio_coding/neteq_opus.rtp  \
  resources/short_mixed_mono_48.pcm

You can replace the RTP and PCM files with any other compatible files. If you get an error using the files indicated above, try running gclient sync.

Requirements: awk and md5sum.
