- Remove the d1x, d2x ebuilds. Gentoo uses the dxx name now, so the old
placeholder ebuilds are no longer needed.
- Update the dxx snapshot ebuild to a current commit.
- Resynchronize the dxx snapshot ebuild from the dxx live ebuild.
- This adds support for USE=valgrind and for USE=data.
- Add a helper script to generate snapshot ebuilds for arbitrary
commits.
