framework: Add new USES 'magick' for graphics/ImageMagick*

A new USES has been added to depend on ImageMagick.

	USES=magick

adds a LIB_DEPENDS on graphics/ImageMagick${IMAGEMAGICK_DEFAULT}.

If a specific version is required, use for example

	USES=magick:6        resp.     USES=magick:7

If only a build, run or test is required, use for example

	USES=magick:build    resp.     USES=magick:6,build,test

Convert to UCL & cleanup pkg-message (categories e-g)

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.

Change cmake default behaviour to outsource.

Ports that build out of source now simply can use "USES=cmake"
instead of "USES=cmake:outsource". Ports that fail to build
out of source now need to specify "USES=cmake:insource".

I tried to only set insource where explictely needed.

Update ImageMagick to 6.9.10.14 [1]

* Add PKGNAMESUFFIX and rename the directory. This was done to show
  that IM6 is not the "main" version. But still fully supported by upstream.
* Convert a number of options to optionhelpers.
* Add option for ISO/IEC 23008-12:2017 HEIF suport
* Add comment to pkg-descr explaining IM6's "legacy" tag.
* Add comment to the patch-config_policy.xml file why it still needed.

Please note that IM7 is not a drop in replacement due to library API and
command arguments changes. And as a result ports need to decide for themself
which version to use.

Chase these changes in all the ports that using IM6.
