+ * crc16
+ *
+ * Computes a crc16 over the input data using the polynomial:
+ *
+ *       x^16 + x^12 +x^5 + 1
+ *
+ * The caller provides the initial value (either CRC16_INIT_VALUE
+ * or the previous returned value) to allow for processing of 
+ * discontiguous blocks of data.  When generating the CRC the
+ * caller is responsible for complementing the final return value
+ * and inserting it into the byte stream.  When checking, a final
+ * return value of CRC16_GOOD_VALUE indicates a valid CRC.
