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
