from docbook format (already in svn).

This updates bindctl.1 and msgq.8 already in svn.

Add Makefile.am additions so these are installed and also
to regenerate them. Assuming the nroff version is newer than the xml
version, make won't need to regenerate. It is created using
xsltproc. But this shouldn't be a build requirement -- so 
may need to redo this if notice any problem.

Also in the loadzone makefile, create the localstatedir. (Not
really needed since other makefile creates, but just in
case this becomes standalone.)
