  level imports: Check the level of exported identifiers
  
  The level imports specification states that exported identifiers have to
  be at level 0. This patch adds the requird level checks that all
  explicitly mentioned identifiers occur at level 0.
  
  For implicit export specifications (T(..) and module B), only level 0
  identifiers are selected for re-export.

  Re CLC issue 292 Warn GHC.Internal.List.{init,last} are partial
  
  Also corrects the warning for `tail` to refer to `Data.List.uncons` (like the existing warning for `head`).
  
  In module `Settings.Warnings`, applies `-Wno-unrecognised-warning-flags` `-Wno-x-partial` to the `Cabal`, `filepath`, `hsc2hs`, `hpc`, `parsec`, `text` and `time` packages (outside GHC's repository).
