The previous workflow is to convert dot diagrams into .pic format and
embed into manpages; double borders and arrows were not used in dot but
introduced in .pic conversion; edge routing in .pic were also worse than
dot.
The updated workflow specifies directly in dot diagram double boarders
for "root set" nodes and solid/bold styles and arrows for edges. The
converted .eps diagram has improved routing. The .eps diagram is
embedded into PDF using groff PSPIC marco package when converting the
manpages. PSPIC package is automatically loaded by groff when output to
PS/PDF.
In addition, 'constraint=false' option is removed from weak references
to allow positioning of node boxes to avoid overlapping between multiple
edges between "Mirror" and "Port" in ovs-vswitchd.conf.db.
