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.

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).
