Modernize copy prevention in KeyLookup to use = delete
----------------
Merge commit message:
Modernize copy prevention in KeyLookup to use = delete
Replace old-style private-and-undefined copy constructor/assignment
with explicit = delete. KeyLookup is a monostate singleton (all
methods and data are static), so copies are meaningless.
