vat: add infrastructure to align vnet test code and plugin test code
Split vat/api_format.c also for VNET features. Use auto-generated VAT test code and support dynamic message ID allocation as for plugins. The arp and geneve features as Guinea pigs. Type: improvement Signed-off-by: Ole Troan <ot@cisco.com> Change-Id: I461591496766bdf10c5f950fd30f1a0ae05909da Signed-off-by: Ole Troan <ot@cisco.com>
