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:

 - parameterize everything.
 - switch to csup.  (This necessitates pushing the repos down one
   directory level, e.g. ports-head/ports and src/src-8.  However,
   this will give us the flexibility to have e.g. src/src-8.1 in
   the future.)
 - note that the misnomer filename 'cvsdone', which was created
   here, is now changed to '.updated'.

Feature safe:	yes
