fpm: Add protobuf support for FPM.
Code that allows a client to convey routes to a Forwarding Plane
Manager component using protobuf instead of netlink..
* fpm/fpm.proto
Protobuf definitions pertaining to the Forwarding Plane Manager.
In particular, this file defines the AddRoute and DeleteRoute
messages.
* fpm/fpm.h
Tweak FPM message header definition to also allow messages to be
encoded in protobuf format.
* fpm/{fpm_pb.h,.gitignore,.Makefile.am}
Add the fpm_pb library, which contains code for interfacing with
the FPM using protobuf.
* configure.ac
Generate fpm/Makefile.
* Makefile.am
Add fpm subdirectory to build.
* common.am
Add flags to be used by clients of the fpm_pb library.
