gnome: remove tracker2

Tracker2 has long ago been replaced by tracker3 which is also gone now
and replaced by tinysparql.

Tracker2 is creating some complication for many ports (including
grilo-plugins) when installed, considering it not supported anymore,
just remove it instead of fighting it in each related port

sysutils/tracker: prepare for vala 0.56.4

sysutils/tracker: fix build with clang 15

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

  src/tracker-store/tracker-store.p/tracker-resources.c:1685:14: error:
incompatible pointer to integer conversion assigning to 'gint' (aka 'int') from
'gconstpointer' (aka 'const void *') [-Wint-conversion]
                  subject_id = _tmp1_;
                             ^ ~~~~~~

This is because in this vala-generated C code, the glib hash table
iterator code always returns pointers, even for integer keys. However,
vala is inflexible in the C expressions it generates to store the
outcome. Suppress -Wint-conversion to get rid of the compile error.

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.

On the FreeBSD front, though, a lot went into this release.  Major thanks
goes to kwm and avl who did a lot of the porting work for this release.
In particular, kwm brought in Evolution MAPI support for better Microsoft
Exchange integration.  Avl made sure that the new gobject introspection

aren't brought in wholesale.

But, every GNOME team member (ahze, avl, bland, kwm, mezz, and myself)
contributed to this release.

The affected ports are the ones with gettext as a run-dependency

Tracker is also extremely fast and super efficient with your systems memory when
