Merge pull request #273 from marineam/gmerge

fix(coreos-base/gmerge): Remove reference to old package.provided file
fix(sys-apps/efunctions): Create functions.sh symlink in postinst.

This makes double sure that the symlink is never removed by INSTALL_MASK
or PKG_INSTALL_MASK. This symlink is so strictly required by random
tools we cannot allow it to ever go missing by mistake.

fix(app-emulation/docker): start with a clean slate
feat(app-emulation/docker): bump to docker 0.7.1
feat(app-emulation/docker): use the coreos unit file

On CoreOS we use systemd to manage docker containers. Having docker
automatically start containers on reboot makes everything confused. Stop
doing this.
Merge pull request #275 from philips/docker-0.7.1

Docker 0.7.1
bump(sys-libs/pam): Import current stable pam from Gentoo
fix(sys-libs/pam): Remove libs from /lib64

This ebuild calls gen_usr_ldscript to move libraries from /usr to / and
then symlinks to them from /usr. Clear all that crap out and use /usr.
