Remove CError.throwCError. Export the new function errnoToIOError.

Add a missing colon in a string inside IOException formed from
the error-specific part and optional filename. The IOException
representation has not changed yet, but IMHO the filename should
be kept separate.

Correctly handle user errors in IO.ioeGet* functions like other
IO errors.

Let fail :: String -> IO a throw a user error instead of invoking error
(Haskell98 is ambiguous about that and IMHO it should be this way;
this is also what nhc does).
