Log message:
We depend on publicfile, so we don't need to duplicate its dependencies
on daemontools and ucspi-tcp{6,}. Bump version.

Log message:
s/ucspi-tcp/ucspi-tcp6/g in dependencies. Bump PKGREVISIONs.

Log message:
*: Move SUBST_STAGE from post-patch to pre-configure

Performing substitutions during post-patch breaks tools such as mkpatches,
making it very difficult to regenerate correct patches after making changes,
and often leading to substituted string replacements being committed.

Log message:
Remove mk/find-prefix.mk usage from the net category.

The find-prefix infrastructure was required in a pkgviews world where
packages installed from pkgsrc could have different installation
prefixes, and this was a way for a dependency prefix to be determined.

Now that pkgviews has been removed there is no longer any need for the
overhead of this infrastructure.  Instead we use BUILDLINK_PREFIX.pkg
for dependencies pulled in via buildlink, or LOCALBASE/PREFIX where the
dependency is coming from pkgsrc.

Provides a reasonable performance win due to the reduction of `pkg_info
-qp` calls, some of which were redundant anyway as they were duplicating
the same information provided by BUILDLINK_PREFIX.pkg.

Log message:
Add publicfile-run, a package that creates the users and group
needed to run publicfile services and provides NetBSD-style rc.d
scripts, in the pkgsrc tradition of qmail-run and djbdns-run. By
