Introduce a new variable "CONF_DEPENDS" for pkgviews: a package's

config directory matches the config directory for the dependency
listed in CONF_DEPENDS.  Use symlinks to physically point the
package's config directory to the dependency's config directory, and
handle all of this in the INSTALL/DEINSTALL scripts.

Also make the INSTALL/DEINSTALL scripts a bit smarter about not
copying files and not removing files if the source and destination
file locations point to the same thing.
