Evolving SRv6 (Segment Routing for IPv6)

Implements:
1.- SR Policies with several (weighted) SID lists
2.- Binding SID
3.- SR LocalSIDs with support for the following functions
	- End
	- End.X
	- End.DX6
	- End.DX4
	- End.DX2
	- End.DT6
	- End.DT2
	- End.B6
	- End.B6.Encaps
4.- SR Steering policies (to steer a traffic through an SR Policy)
	- Support for IPv6 traffic (IPv6 Encapsulation / SRH insertion)
	- Support for IPv4 traffic (IPv6 Encapsulation)
	- Support for L2 traffic
	(T.Insert / T.Encaps)
5.- Doxygen documentation
6.- Framework (APIs) to allow the definition of new SR LocalSID behaviors by means of plugins
7.- Sample SRv6 LocalSID plugin
