NLSR

https://gerrit.named-data.net/c/NLSR/+/6069:

• Eliminates src/tlv folder
  • Tests are also moved to the respective route classes tests
• Uses Name instead of separate Destination TLV in Routing Table Dataset
• Introduces RoutingTableStatus as parent class of RoutingTable, so that Nlsrc code can construct RoutingTableStatus without any argument.

Bot machine is unable to build the change to test despite jenkins passing as the compiler on bot machine seems old.
