Newly added tags

Few CDNs recommend to have following tags in FLV headers, in rtmp stream. 

• videocodecid
• audiocodecid
• audioonly
• videoonly
• stereo
• width
• height
• videodatarate
• audiodatarate
• audiosamplerate
• audiosamplesize
• audiochannels
• framerate
• avcprofile
• avclevel
• aacaot

But current flvmux do not have few of them. I have added missing tags, and
validated it. Seems to be working, please find patch in the attachment.
Can some one review the patch ??

One can use following pipeline for testing:

gst-launch-1.0 videotestsrc is-live=1 !
video/x-raw,width=176,height=144,framerate=25/1 ! x264enc ! flvmux
streamable=true name=mux ! fakesink audiotestsrc !
audio/x-raw,rate=48000,channels=2,format="S16LE" ! voaacenc bitrate=24000 !
mux. --gst-debug=*flv*:5
