From 2173088340e49a695a829f53a087deb9fa9749cb Mon Sep 17 00:00:00 2001

Subject: 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.

Several bugs are fixed and improvements are made:

 - archive directories are created  if they do not exist.
 - the location of ZFS-based directories is generalized.
 - the special string "-exp" disappears.
 - handling of buildid is made more robust.

Feature safe:	yes
