zebra: optionally use protobuf with FPM
Change zebra so that it can optionally use protobuf serialization when
communicating with a Forwarding Plane Manager component.
* zebra/main.c
Add the --fpm-format/-F command line option. This allows the user
to control the format (protbuf|netlink) that is used to
communicate with the FPM.
* zebra/zebra_fpm.c
- zebra_init_msg_format(),
This new function is invoked on process startup to determine the
FPM format that should be used.
- zfpm_init()
Change to accept any 'FPM message format' specified by the user
(via the new command line flag).
- zebra_encode_route()
Tweak to use the selected FPM format.
* zebra_fpm_protobuf.c
New code to build protobuf messages to be sent to the FPM.
* zebra/Makefile.am
- Include common.am
- Build new file zebra_fpm_protobuf.c when protobuf is available.
- Link with the fpm_pb library.
