nrelease: Switch over to dports for all packages.
nrelease - Set dports default, add dports defaults

* Default DPORTS_PATH to /usr/dports.

* Add dports defaults for the git build to match the git we intend to
  prepackage with the installation.
pkg_radd - update to also handle dports

* Detect that dports has been installed.  dports takes priority over
  pkgsrc in this situation.

* For dports we just 'pkg install ...'.  The script also warns if the
  /usr/local/etc/pkg.conf file has not been installed.

carp: Perfer addresses with prefix route installed.
carp: Take netmask into consideration when picking up backing address
carp: Fix routes reset issue

Before this commit, routes related to carp or carp backing device were
reset, i.e. only prefix route was left, when carp state changed, e.g.
carp is down.

This commit fixes this routes reset issue by replacing the carp or carp
device routes' rt_ifa and rt_ifp with proper ifaddr and ifnet, instead
of discarding the old routes and installing the new prefix route.
