Remove portbuild scripts from pcvs, as they now live in svn/projects.

23:02 linimon 

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.

While here, do some cleanup.

Feature safe:   yes

Improve error handling a bit.

Oops, commit the right version of this (adds extra checks that only
expected commands will be proxied)

* Python daemon run as root that proxies privileged build commands for
  the ports-* users.  Currently it is not possible to delegate
  management of ZFS filesystems to non-root users, so root privilege
  is required to manipulate them.  We validate the command passed on
  a local domain socket and re-execute the build script with the requested
  parameters.
