Log message:
Remove USE_DIRS from pkgsrc.

Shared directories can now be created independently by the pacakges
needing them and will be removed automatically by pkg_delete when empty.

Packages needing empty directories can use the @pkgdir command in PLIST.

Discussed and ok'd in thread starting at
http://mail-index.netbsd.org/tech-pkg/2009/06/30/msg003546.html

Log message:
Remove @dirrm related logic.

Log message:
Convert @exec/@unexec to @pkgdir or drop it.

Remove @dirrm entries from PLISTs

Log message:
cleanup: replaced _PKG_SILENT and _PKG_DEBUG with RUN.

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Add an ignore pattern.

Log message:
Drop maintainership

Stop lying and drop maintainership of these packages.  I have not
maintained them for a very long time already, so leave room for
fresh blood to take over them.

Log message:
Don't depend on gtk2+ package just to be able to update an icon cache file.
Instead update the cache iff gtk2 package also installed.
OKed wiz and jmmv.  Bump PKGREVISION.

Log message:
Replace mk/bsd.prefs.mk includes with bsd.fast.prefs.mk includes.
The redundant parsing of bsd.prefs.mk is mostly avoided now and
parse time e.g. for x11/kdebase3 gets reduced by up to 10%.
