[doc] document version zserv header, add txt figures, make pdf figs nicer

2006-03-31 Paul Jakma <paul.jakma@sun.com>

	* fig*.txt: New files, txt versions of the diagrammes for the
	  info file.
	* protocol.texi: Document the new version 1 header.
	* routeserver.texi: Explicitly specify scaling widths for the
	  figures, only way to make them look reasonable, sadly.
	  Try fix some formatting and explicitely note lists as being
	  bulleted.
	* Makefile.am: convert seems to do png to pdf just fine. No
	  need for intermediate eps.
	  Add txt figure expansions and list as dependencies and
	  EXTRA_DIST files.
