Make everything a bit faster.

0) Issues several prayers and sacrifices to Enki under threat of a terrible deluge sent down by Ellil
1) Convert fork-write/read exprs to be non-forking
2) Pass mostly everything by reference
3) Don't bother cleaning the variable namespace because Bourne shell is an abomination
4) Removes broken ./pkgtool.sh -s, --restart-at, --update-diff & ./build.sh --dump-{in,on-abort}
5) Cleanup
