Rename the package nut22 to avoid collision with sysutils/nut

Add NO_STAGE all over the place in preparation for the staging support (cat:

Finish converting the whole ports tree to USES=pkgconfig

Drop support for old versions of FreeBSD from unmaintained ports

Convert to new options framework

Move the rc.d scripts of the form *.sh.in to *.in

Where necessary add $FreeBSD$ to the file

No PORTREVISION bump necessary because this is a no-op

new devel/pkgconf added to replace devel/pkg-config. new version of pkg-config
are no more self hosting so we are stuck with 0.25 version while pkgconf provide
the same set of features as 0.27 and a compatible frontend. A symlink to
pkg-config has been added for convenience and compatibility

This also introduces a new macro to use pkgconf in your ports:
USE_PKGCONFIG

it can take the following arguments:
 - yes (meaning build only dep)
 - build (meaning build only dep)
 - run (meaning run only dep)
 - both (meaning run and build dep)

From now USE_GNOME= pkgconfig is deprecated in favour of USE_PKGCONFIG
The old gnome macro has been modified to use pkgconf but still the sameway: run
and build dep to avoid large breakage.

While here fix some ports relying on pkg-config but not specifying it, fix some
ports broken because testing wrong .pc files, and fix ports using pkg-config
--version to determine pkg-config version instead of
pkg-config --modversion pkg-config like recommanded by pkg-config

For the ports that are maintained by ports@ that have pkgconfig as their
only USE_GNOME feature, convert to a BUILD_DEPENDS. This avoids both the
bug of the bogus run depend introduced by bsd.gnome.mk, and also avoids
needlessly pulling that file in.

In the rc.d scripts, change assignments to rcvar to use the
literal name_enable wherever possible, and ${name}_enable
when it's not, to prepare for the demise of set_rcvar().

In cases where I had to hand-edit unusual instances also
modify formatting slightly to be more uniform (and in
some cases, correct). This includes adding some $FreeBSD$
tags, and most importantly moving rcvar= to right after
name= so it's clear that one is derived from the other.

- Makes neon29 our default neon library. The neon 0.27.x to 0.29.x are API and
  ABI backwards compatible. It is unnecessary to have more than one same
  libraries (ie: neon28 and neon29) as it creates issue in our ports tree such
  as CONFLICTS and made our Makefile complicate.
- Remove www/neonpp and www/neon28.
- Add USE_GNOME=ltverhack; it corrects the shared library version by change
  from libneon.so.29 to libneon.so.27. It won't get bump again with no reason
  unless ABI changes.
- Bump the PORTREVISION on all ports and chase the shared library change.
- Add info in the UPDATING for how to rebuild on all ports that depend on
  neon.
