celtdec : chain_parse_data : check validity of timestamp, create a new one if needed

Browse source 
celtenc : default framesize is 480
          setcaps : gets framesize and set caps
          enc_chain : sets framesize in caps
          Added frame-size to static caps of audio/x-celt
          Replaced GST_DEBUG_OBJECT by GST_LOG_OBJECT in enc_chain
          setcaps: get frame-size from int instead of string
          setcaps: use default value for frame-size
