Start to add support for DirectX 8 vertex shaders, constants and
registers are now correctly assigned and loaded allowing support for
most basic d3d8 shaders.

The BytesRead parameter passed to ReadFile may never be NULL.

On Win9x,ME RegCreateKeyEx ignores the backslash character if the
subkey begins with one. With a regression test.

Add a framework for writing the strings for marshaling and
unmarshaling parameters and make the client and server use it.

- Add framework for updating proc offsets.
- Write out argument lists in the server.

- better render_texture emulation (using pbuffers)
- support GLX_ATI_render_texture for render_texture

In HttpQueryInfo if dwInfoLevel includes HTTP_QUERY_CUSTOM then
lpBuffer is In/Out because the header we are querying is there.
Additionally standard headers can be queried in this manner as well
(such as Set-Cookie).

- Fix device probing at driver load time.
- Fix memory leaks at driver exit time.

- add directx9 support for dplay8.h and dpaddr.h
- new file dplobby8.h

- return correct MM error code when no connection to server has been
  opened
- don't close the AU driver if it hasn't been opened

When converting SendRequestExA -> W we need to set the lpcszHeader
parameter to NULL if the original one is NULL.

Fixed the return value type.

Fix DispCallFunc to work with MSDN-undocumented behaviour used by
Office 2003 and document the function.

Fix more fallout from dispinterface retval patch: make typelib
marshaler use the internal function description so that it calls
dispinterface functions with the correct number of parameters again.
Also fixes some memory leaks caused by the fact that a corresponding
ReleaseXDesc function has to be called for each GetXDesc.
