- Move some of the screen mode related functions into wined3d and add
  untested support for the new d3d9 options of providing the format to
  some of the calls.
- Move other functions from the directx interface into the common
  library and implement the calls from d3d9 as well.
- Copy across the first of the functions used to make traces more readable,
  creating utils.c to store them in. Eventually the ones in d3d8 will be
  removed but for now just duplicate the code.
