- Implement D3DSIO_DP2ADD, D3DSIO_TEXKILL, D3DSIO_TEXM3X3PAD
- Partially implement D3DSIO_TEXBEM, D3DSIO_TEXM3X3VSPEC (as much as
  they are implemented in ARB_fragment_program at least).
- Stop copying the SHADER_PARSE_STATE struct in each ARB shader
  routine - use a pointer instead.

Really check in MCI open string commands if the name we have is a
device (and no longer rely on bad heuristics for it).

- added the elf_is_in_thunk_area() function to locate an address
  within the known thunk area of Wine's builtin modules
- now passing this thunk information to the dwarf parser so that it
  can drop functions from the thunk areas (as dwarf symbols), so that
  those functions can be later on marked as thunks in dbghelp
  internals

Enhancement over previous fix (we don't need to insert NOTYPE symbols
in our public symbol table, so drop them as early as possible).

Compute the default verb as documented on MSDN instead of blindly
assuming it is 'open'. This fixes the WordViewer association in some
cases.

Tell gl to draw to the back buffer when a back buffer is used, do not
use the value from gl.
