    Switch from -this-package-key to -this-unit-id.
    
    A small cosmetic change, but we have to do a bit of work to
    actually support it:
    
        - Cabal submodule update, so that Cabal passes us
          -this-unit-id when we ask for it.  This includes
          a Cabal renaming to be consistent with Unit ID, which
          makes ghc-pkg a bit more scrutable.
    
        - Build system is updated to use -this-unit-id rather than
          -this-package-key, to avoid deprecation warnings.  Needs
          a version test so I resurrected the old test we had
          (sorry rwbarton!)
    
        - I've *undeprecated* -package-name, so that we are in the same
          state as GHC 7.10, since the "correct" flag will have only
          entered circulation in GHC 8.0.
    
        - I removed -package-key.  Since we didn't deprecate -package-id
          I think this should not cause any problems for users; they
          can just change their code to use -package-id.
    
        - The package database is indexed by UNIT IDs, not component IDs.
          I updated the naming here.
    
        - I dropped the signatures field from ExposedModule; nothing
          was using it, and instantiatedWith from the package database
          field.
    
        - ghc-pkg was updated to use unit ID nomenclature, I removed
          the -package-key flags but I decided not to add any new flags
          for now.
