Return to Makefile CVS log

Up to [local] / src / usr.bin / make

adjust to ohash being in libutil now, and to the interface changes.
fix potential integer overflows in memory allocation (mostly for pedagogical
purposes, these are unlikely to overflow in practice)
move the rest of lst.lib stuff into its own directory.
