GL_LIMITS(textures) is currently used for both the number of texture
stages and the maximum number of simultaneous textures. In the current
code that's the same, but in a later patch that will be separated,
since a texture stage doesn't have to reference an actual
texture. Also, shaders can access a larger number of samplers than the
number of texture units the fixed function pipeline can access.

Show a confirmation dialog in SHFileOperationW for the FO_DELETE
operation when called without FOF_NOCONFIRMATION or with
FOF_WANTNUKEWARNING. That way the user's files won't be deleted
without a warning.

This means we don't need to add checks for NULL libxml node ptrs in our node implementation.

when requesting info on a module by address, always print the module
ELF/PE pair (if this applies) (and not only the embedded PE), which
can be confusing.

This allows reimplementing the module list command and do less black
magic to guess the ELF debug format.

- now internally storing module info as a 64bit module structure
  (the interest in not in the 64 bit side of things, but because
  it allows storing lots of usefull information)
- fixed SymGetModuleInfo64W which wasn't returning the
  LoadedPdbName field
- now filling for MSC files with the extended information
  (instead of guessing it)
- reused the extended module info to store wine ELF module
  information (link for map link, stabs vs dwarf symbol info)

- 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.
