Changes related to arithmetic types:

* Renamed macros NUMERIC_FOO to ARITHMETIC_FOO to match C99-speak

* ARITHMETIC_TYPEs now have a Real instance, otherwise they are quite useless.
  Note that this differs from the FFI spec, but the spec should very probably
  changed in this respect.

* Some changes to fix the wrong assumption that CTime/CClock are integral types,
  C99 in fact guarantees only that they are arithmetic types. This has been
  accomplished by using

     realToInteger = round . realToFrac :: Real a => a -> Integer

  instead of fromIntegral for CTime/CClock. I'm not sure if we could do better,
  going via Double seems to be overkill, but I couldn't think of a better way.
  GHC could e.g. use RULES here. Improvements welcome.
