[zserv] Extend Zserv header with version information and marker field
2006-01-16 Paul Jakma <paul.jakma@sun.com>
* lib/zclient.h: Update the Zserv protocol header with a version
field. Define the old command field to be a 'marker', to
allow old Zserv and updated Zserv to be differentiated.
Future updates will bump the version field obviously. New
command field is made wider. Try to stop using the
'zebra_size_t' typedef in the callbacks.
* lib/zclient.c: Update to read/write new format header.
* zebra/zserv.c: Ditto
