The tool RTPanalyze (used to process an input RTP dump into a text file of RTP header info) was present in both the neteq and neteq4 folders. This change pulls in changes from the old to the new and renames the source file and tool to rtp_analyze. Removing special code for dummy-rtp files (it is supported without special code), and making the RED payload type settable using flags. Moving from test/ to tools/ folder.
