    This cleans up the package subsystem a little.  There are some
    changes to the GHC API as a result.
      - GHC.init and GHC.initFromArgs are no longer necessary.
      - GHC.newSession takes the root of the GHC tree as an argument
        (previously passed to GHC.init).
      - You *must* do GHC.setSessionDynFlags after GHC.newSession,
        this is what loads the package database.
      - Several global vars removed from SysTools
      - The :set command in GHCi can now cause new packages to be loaded,
        or can hide/ignore existing packages.
