Add ovs_flow, ovs_vport and ovs_datapath to the families supported
in C. ovs-flow has some circular nesting which is fun to deal with,
but the necessary support has been added already in the previous
release cycle.
Add a sample that proves that dealing with fixed headers does
actually work correctly.

Configuring / reading ring sizes and counts is a fairly common
operation for ethtool netlink. Present a sample doing that with
YNL:
$ ./ethtool
Channels:
enp1s0: combined 1
eni1np1: combined 1
eni2np1: combined 1
Rings:
enp1s0: rx 256 tx 256
eni1np1: rx 0 tx 0
eni2np1: rx 0 tx 0

Add a sample to show off how to issue basic devlink requests.
For added testing issue get requests while walking a dump.
$ ./devlink
netdevsim/netdevsim1:
driver: netdevsim
running fw:
fw.mgmt: 10.20.30
...
netdevsim/netdevsim2:
driver: netdevsim
running fw:
fw.mgmt: 10.20.30

Add a sample application using the C library.
My main goal is to make writing selftests easier but until
I have some of those ready I think it's useful to show off
the functionality and let people poke and tinker.
Sample outputs - dump:
$ ./netdev
Select ifc ($ifindex; or 0 = dump; or -2 ntf check): 0
lo[1] 0:
enp1s0[2] 23: basic redirect rx-sg
Notifications (watching veth pair getting added and deleted):
$ ./netdev
Select ifc ($ifindex; or 0 = dump; or -2 ntf check): -2
[53] 0: (ntf: dev-add-ntf)
[54] 0: (ntf: dev-add-ntf)
[54] 23: basic redirect rx-sg (ntf: dev-change-ntf)
[53] 23: basic redirect rx-sg (ntf: dev-change-ntf)
[53] 23: basic redirect rx-sg (ntf: dev-del-ntf)
[54] 23: basic redirect rx-sg (ntf: dev-del-ntf)
