Remaining L3Protocol with wrong names

I think these are the final names I got wrong.
NNN Face fixed to current code status

The NNN face files have been modified to accept all the defined packets.
Forwarding to create the Forwarding strategies

All these files have been modified to get closer to having a functional NNN
stack.

I still haven't decided how I will implement the NNPT or NNST, but now I know
that I need the auxiliary functions that I have been fixing in these files.
NNPT and NNST table files

I think these will be the final header files that I will have to add, for now.

nnn-face-container.{h,cc} is a finished copy and is ready for use.
