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

Remove # $FreeBSD$ from Makefiles.

net-im: Add missing USES={gnome,xorg}

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.

Convert net-im/libpurple (and slave ports net-im/finch and net-im/pidgin)
to "USES=libtool tar:bzip2".  Bump PORTREVISION on all dependent ports
and modernise them as well (USES, LIB_DEPENDS, staging).

audio/pidgin-musictracker:
- Replace LIBS with LDFLAGS.
- Disable static plugin.

net/online-desktop: Remove obsolete patches.

net-im/mbpurple:
- Drop pkgconf dependency.
- Replace post-patch with MAKE_ARGS.
- Use standard do-build.

Add NO_STAGE all over the place in preparation for the staging support (cat:
net-im)

Add explicit dependency on pkgconf (8 ports)

Rectify USE_TEX to support both of teTeX and TeXLive.

TEX_DEFAULT:
	A knob to choose teTeX or TeXLive.  One can specify in /etc/make.conf.

USE_TEX:
	A knob for port developers.  Valid keywords are listed in
	bsd.tex.mk.

Remove *_DEPENDS from ports which depend on teTeX and add USE_TEX=tetex
instead to make migration to TeXLive easier.
