[lib] Add string mapping table for Zserv commands

2006-05-15 Paul Jakma <paul.jakma@sun.com>

	* log.c: (general) Generalise struct zebra_route_desc into
	  struct zebra_desc_table and, similar to route_types, add a
	  command_types table to describe Zserv protocol commands.
	  (route_types[]) use a macro to use designated initialisers
	  while avoiding tedious duplication.
	  (zserv_command_string) lookup string from zebra_desc_table,
	  similar to zebra_route_string
	* zebra.h: Add declaration for zserv_command_string, adjust the
	  comments to reflect zebra_desc_table.
