        * X11Structs.cs : added couple of structs for XIM support.
        * X11Keyboard.cs :
          Release XIM in case it failed to create XIC.
          Use consts for XNblah string.
          Add support for IM style customization and XIC creation
          for preedit-position and preedit-callback.
          Right now use MONO_WINFORMS_XIM_STYLE environment variable
          (list of: over-the-spot | on-the-spot | root). Only root
          mode works so far.

          (redoing r99172 with fix.)
