Log message:
Drop maintainership.  I can't seriously be the maintainer of so many
packages - specially of packages that I haven't touched for a long
while or those that other people can handle better than me.

Log message:
DEPENDS and PKGREVISION bumps because db4's library name changed.

Log message:
Recursive PKGREVISION bump for gnutls shlib major bump.
Bump BUILDLINK_RECOMMENDED.

Log message:
Do not install gtodo_tray.png, which is installed by time/gtodo.

Log message:
Remove the abuse of buildlink that was pkg-config/buildlink3.mk.  That
file's sole purpose was to provide a dependency on pkg-config and set
some environment variables.  Instead, turn pkg-config into a "tool"
in the tools framework, where the pkg-config wrapper automatically
adds PKG_CONFIG_LIBDIR to the environment before invoking the real
pkg-config.

For all package Makefiles that included pkg-config/buildlink3.mk, remove
that inclusion and replace it with USE_TOOLS+=pkg-config.

Log message:
Change path from devel/pkgconfig to devel/pkg-config.
No PKGREVISION bump since pkg-config is only a BUILD_DEPENDS.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
Add RMD160 checksums.

Log message:
Libtool fix for PR pkg/26633, and other issues.  Update libtool to 1.5.10
in the process.  (More information on tech-pkg.)

Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.

Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.

Log message:
Make use of the new USE_DIRS variable, instead of directly depending on the
*-dirs packages.
