Modified to eliminate the '+1' in the various pstr structure typedefs. Also, created p80211item_maxitemlen to calculate the size of a did-len-data triple. Changed p80211item_getoffset to call p80211item_maxitemlen as opposed to the hardcoding so that the data size of an item is only calculated in one place.
