x11-toolkits/pangox-compat: fix build with clang 16

Clang 16 has a new error about incompatible function types, which shows
up when building x11-toolkits/pangox-compat:

basic-x.c:687:23: error: incompatible function pointer types assigning to 'void
(*)(PangoEngineShape *, PangoFont *, const char *, unsigned int, const
PangoAnalysis *, PangoGlyphString *, const char *, unsigned int)' (aka 'void
(*)(struct _PangoEngineShape *, struct _PangoFont *, const char *, unsigned int,
const struct _PangoAnalysis *, struct _PangoGlyphString *, const char *,
unsigned int)') from 'void (PangoEngineShape *, PangoFont *, const char *, gint,
const PangoAnalysis *, PangoGlyphString *)' (aka 'void (struct _PangoEngineShape
*, struct _PangoFont *, const char *, int, const struct _PangoAnalysis *, struct
_PangoGlyphString *)') [-Wincompatible-function-pointer-types]
  class->script_shape = basic_engine_shape;
                      ^ ~~~~~~~~~~~~~~~~~~

This is because the 'script_shape' callback function in pango 1.50 has
the 'length' argument as 'unsigned int', and also two additional
parameters 'paragraph_text' and 'paragraph_length'. Even though it looks
like this callback function is never used, correct the arguments to fix
the error.

x11-toolkits/pangox-compat: fix build with clang 15

During an exp-run for llvm 15 (see bug 265425), it turned out that
x11-toolkits/pangox-compat failed to build with clang 15:

  pangox.c:983:15: error: incompatible integer to pointer conversion assigning
to 'PangoFontMetrics *' (aka 'struct _PangoFontMetrics *') from 'int'
[-Wint-conversion]
        metrics = pango_font_metrics_new ();
                ^ ~~~~~~~~~~~~~~~~~~~~~~~~~
  pangox-fontmap.c:944:9: error: incompatible integer to pointer conversion
initializing 'char *' with an expression of type 'int' [-Wint-conversion]
    char *files_str = pango_config_key_get ("PangoX/AliasFiles");
          ^           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This is because pangox-compat uses two private functions from the main
pango library, which are not declared in the public pango headers.

Fix the errors by adding the two private functions in
pango-impl-utils.h, copying the declarations from pango-font-private.h
and pango-utils-private.h.

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.

Approved by:		portmgr (tcberner)

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.

cleanup: remove '$MCom' tag

gnome@ no longer uses Marcusom as their staging ground.

Add USES=xorg USES=gl, ports categories x

Add USES=xorg and USES=gl to ports in categories starting with 'x'
While here, try to sprinkle other USES (mostly gnome and sdl) as needed.

Remove libintl.so.9 compatibility link that was added in r374303 to
prevent massive PORTREVISION bumps.  Bump dependent ports that have not
been bumped since.

Remove ${PORTSDIR}/ from dependencies, categories v, w, x, y, and z.

The FreeBSD GNOME team presents a Glib and Gtk+ 3 update.

This update updates Glib20 to 2.36 and Gtk+ 3.8

* The gio-fam-backend port that used gamin for the GFileMonitor API is gone.
  It is replaced by a GIO kqueue implementation developed as part of a NetBSD
  GSoC 2011 project by Dimitry Matveev.
* Fix a bug in the glib20 Makefile so it includes -lintl in the glib-2.0
  pkgconfig file [1]. This broke static linking and newer binutils.
* Add introspection USE_GNOME component which sets GI_SCANNER_DISABLE_CACHE to
  prevent creation of /  root/.cache dir. Defaults to build & run depend,
  but :build and :run switches available.
* New x11-toolkits/pangox-compat port and companion USE_GNOME component for
  pangox support which was removed from the pango port. Add it to ports still
  using pangox API.
