1. suppport mesh type, mesh ID, router and IE crypt func&key at any time after mesh is initalized. 2. support modify parent at any time after mesh is configured. 3. modify manual networking example. 4. update header file. 5. fix issues in root conflicts handling. 6. add max length of beacon to menuconfig. 7. fix issue when received a beacon without DSSS.
