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
This script may be run on a client machine to force it to flush its squid
cache. This is useful if the client is holding a bad or stale cached
copy of a package that is causing problems for package builds.
