Initial import: SBo-danix repo setup, sbshadow, sbpull

slackrepo_setup_SBo-danix.sh rebuilds the personal SBo-danix repo from
upstream plus the personal and pentesting subtree overlays. Shadowing is
delegated to sbshadow, which reconciles both ways against the pristine
current branch (shadow packages now carried in an overlay, restore those
no longer carried) and then runs mkhint -F. sbpull.bash provides the
sbpull shell function that pulls one overlay subtree and runs sbshadow.
