mwan3: optimize the process of copying routing tables

Browse source 
- The original copy process is to delete all routing tables first,
   then add new routing table. This process is too slow and very dirty.
 - We use grep to identify the changes and apply them.
 - ignore ipv6 unreachable routes
 - update version number
