Generalize the packge building scripts to be able to be run on more than

one 'head' node, rather than just pointyhat itself.

Constants are factored out into installation-specific files known as
portbuild/conf/server.conf and portbuild/conf/client.conf.  There is
only one server.conf file.  Individual <arch> directories may have
their own client.conf files, or may symlink to ../conf/client.conf.

This first set of files only gets the *.conf files and some cleanup.

Feature safe:	yes
