New feature: Simultaneous playback of 3 pcap files

[Valik0]

Simultaneous playback of 3 pcap files (audio, video, and images)

Example:

 <nop>
     <action>
       <exec play_pcap_audio="audioTest.pcap"/>
       <exec play_pcap_video="videoTest.pcap"/>
     </action>
 </nop>

Thanks for the PR.

While I see how this could be useful, I very much dislike the copy-paste pattern you used here though.

FreeSwitch also support RTT media (RFC4103)
Could you also add this media support.
PCAP example of RTT media is attached.
rtt.pcap.gz

RTT usage case described here

@sergey-safarov: that's really something for a separate issue
