The GTK 1-based gdk-pixbuf has not existed for some time.

No functional or package changes.

graphics/gimp-lensfun-plugin: make compatible with exiv2 0.28

PR:		272311

Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

graphics/gimp-lensfun-plugin: update to latest git commit

- Take maintainership
- Update to latest 0.2.5-dev commit with fixes:
** Sony lens not detected
** Add GoPro to CameraMakers list
** Wrong lens detected for Fujifilm X-E2
** Fix for exiv2 >=0.27.1

Chase shlib version bump of `graphics/lensfun' (r524150).

Bump PORTREVISION for ports depending on the canonical version of GCC
as defined in Mk/bsd.default-versions.mk which has moved from GCC 8.3
to GCC 9.1 under most circumstances now after revision 507371.

This includes ports
 - with USE_GCC=yes or USE_GCC=any,
 - with USES=fortran,
 - using Mk/bsd.octave.mk which in turn features USES=fortran, and
 - with USES=compiler specifying openmp, nestedfct, c11, c++0x, c++11-lang,
   c++11-lib, c++14-lang, c++17-lang, or gcc-c++11-lib
plus, everything INDEX-11 shows with a dependency on lang/gcc9 now.

Update graphics/exiv2 to 0.25.

As there is an shlib version bump, bump them portrevision of dependent ports.

While doing so, also switch to the cmake build system, as it requires less
patching and is easier to handle.

Update lensfun to version 0.3.0.  It contains few changes making consumer
code incompatible with earlier versions; particularly, removal of CCI (the
Color Contribution Index of the lens, as defined by ISO 6728-83) [1] and
FOV1 ("field-of-view") [2] distortion model.

Four ports had to be patched to build against new lensfun (all fall under
`graphics' category): digikam-kde4, gimp-lensfun-plugin, hugin, rawstudio.

Upgrade OpenEXR and ilmbase to 2.2.0.

GCC 4.2 in FreeBSD 8.X/9.X base is now too old to compile OpenEXR, so
GCC-based systems will upgrade to the default ports compiler (GCC 4.7
currently.)

Add two patches to OpenEXR to permit building it in a live system with
the older OpenEXR version installed. Bug report filed to upstream Github
at https://github.com/openexr/openexr/issues/130

Couple OpenEXR more tightly to ilmbase and require its exact .so
version.

Add UPDATING note, and bump PORTREVISION of all dependent ports.

Proto-STAGE hugin-devel, and mark it IGNORE because hugin is newer.
