Bug 1068544 - Support transceive function for nfcd. r=allstars.chh

The reason i use uint8 array instead of  vector is because of NFA_SendRawFrame of libnfc-nci takes uint8 array as parameter, to avoid additional memory copy so I didn't use vector.
Do you think this is ok or you prefer use vector for both ? another option is both use uint8 array
