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.

textproc/libxml2: bump all dependencies

This should make sure that all dependent ports will pick
up the new version commited with a13ec21cd733f67a9fc0dc00ab45268bdc236246

INSTALLS_ICONS: retire the macro and rework the related dependencies

While here, make sure gtk-update-icon-cache is only on run dependency
where added as a dependency
Enforce gtk3 to depend on gtk-update-icon-cache (previously it was
inheriting the dependency)

Remove # $FreeBSD$ from Makefiles.

Prefer graphics/ligvrsvg2-rust over graphics/librsvg2

- switch to the more modern version of librsvg2 on architectures
  supporting rust
- this will fix some graphical issues on these architectures

- Fix leftover files generated by shared-mime-info

Approved by:	kwm

Split devel/gettext in devel/gettext-runtime and devel/gettext-tools.  The
first contains runtime libraries such as libintl and the latter contains
developer tools such as msgfmt.  Ports that use gettext will usually need
a LIB_DEPENDS on gettext-runtime and a BUILD_DEPENDS on gettext-tools.

USES=gettext-runtime can be used to set a LIB/BUILD/RUN_DEPENDS on
devel/gettext-runtime and USES=gettext-tools can be used to set a
BUILD/RUN_DEPENDS on devel/gettext-tools.  USES=gettext is now the same
as "USES=gettext-runtime gettext-tools" meaning a LIB_DEPENDS on
devel/gettext-runtime and a BUILD_DEPENDS on devel/gettext-tools.

Update gettext to 0.19.3.

Remove :oldver from converters/libiconv and devel/gettext-runtime.  Leave
symlinks with the old library versions to avoid the need to bump
PORTREVISION on a large number of dependent ports.  When most of the
dependent ports have had normal version updates, PORTREVISION can be
bumped on the remaining ones (low number) and the links can be removed.

Fix some ports that installed files in lib/locale instead of share/locale.
