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.

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.
The grand plan with gnome-mount is to get the appropriate GNOME
software (such as gnome-volume-manager and gnome-vfs) to use this
instead of invoking mount(1)/umount(1)/eject(1) / invoking methods on
HAL directly.
Included in gnome-mount is also gnome-umount and gnome-eject. All
programs utilize the methods on HAL and as such run unprivileged. The
rationale for gnome-mount is to have a centralized place (in gconf)
where settings (e.g. mount options, mount location) are
maintained.
