I cleaned up the bitfields for the avdtp packets and committed it...

Do you think this looks right for covering the header on avdtp page 45?

// remember htobs() for converting from host to bluetooth byte ordering
// when putting data in this struct
typedef struct {
   uint8_t v:2;
   uint8_t p:1;
   uint8_t x:1;
   uint8_t cc:4;
   uint8_t m:1;
   uint8_t pt:7;
   uint16_t sequence_number;
   uint32_t timestamp;
   uint32_t ssrc;
   uint32_t csrc[0];
} __attribute__ ((packed)) media_packet_header;

If that looks like the right direction, I need to work on delineating 
the sbc frames inside the sbc file so i can put on the media packet 
headers and the media payload headers. Is it straightforward?
