Remove some old gnome2 ports not depend on anymore and not maintained upstream

Remove ${PORTSDIR}/ from dependencies, Mk and categories a, b, and c.

Cleanup plist

Replace USES=libtool:oldver with USES=libtool or USES=libtool:keepla in
the 32 ports that still use it.  Bump PORTREVISION on their dependent
ports except the ones that depend on these:

audio/libogg
audio/libvorbis
devel/pcre
ftp/curl
graphics/jpeg
graphics/libart_lgpl
graphics/tiff
textproc/expat2
textproc/libxslt

In these cases the same trick as in the recent gettext update is used.

Convert from USE_GNOME=gnomehack -> USES=pathfix

While here:
- Strip binaries
- Convert USE_BZIP2 -> USES=tar:bzip2
- Convert to USES=libtool
- Remove tests for gnopernicus as they badly track the dependencies they
  needs and fails to build with non recursive ld(1)
- orca does not need pathfix at all

Stage all gnome@ ports in accessibility, which finishes this category!

Add no stage all over the place in accessibility in preparation for the staging
area support

Add an explicit dependency on pkgconf

Finish converting accessibility from USE_GMAKE to USES=gmake
While here:
- trim some headers
- convert from USE_GNOME=pkgconfig to USES=pkgconfig

or updated
Requested by:   edwin

Bump portrevision due to upgrade of devel/gettext.

The affected ports are the ones with gettext as a run-dependency
according to ports/INDEX-7 (5007 of them) and the ones with USE_GETTEXT
in Makefile (29 of them).

Presenting GNOME 2.18 for FreeBSD.  GNOME 2.18 is a departure from recent GNOME
releases in that it focuses more on stability and functionality than on
new features.  Not that it doesn't have its share of new and exciting
items.  See http://www.gnome.org/start/2.18/ for all the goodies in
this release.

GNOME 2.18 for FreeBSD would not have been possible without the hard work
of the FreeBSD GNOME Team and our intrepid band of testers including
J. W. Ballantine, Pawel Worach, Yasuda Keisuke, Pascal Hofstee, miwi,
Yoshihiro Ota, Vladimir Grebenschikov, Jukka A. Ukkonen,
Phillip Neumann, Franz Klammer, and Neal Delmonico.
