vertex_desc.Pool should obviously be used in the 
WINED3DRTYPE_VERTEXBUFFER case instead of index_desc.Pool.

The base version won't suffice anymore as it is not able to upload
palette changes to the drawable in an efficient way for both GDI and
GL. Further the LoadLocation code in RealizePalette isn't needed for
the GDI version as in all cases it works on system memory.

wininet/tests: Don't include the trailing '\0' in dwHeadersLength otherwise HttpSendRequestEx() sends it too which some servers object to.

wininet: Document HttpAddRequestHeadersW()'s handling of the trailing '\0'. Fix tracing of the corresponding header strings as they may not be '\0' terminated.

advapi32/tests: Check whether RegGetValue() '\0'-terminates the buffer when retrieving a zero-byte string value.

advapi32/tests: Remove an obsolete comment: Wine's on-disk registry format now supports string values with no trailing '\0'.

msi: Use 'HKCU\Software\Microsoft\MS Setup (ACME)' as a source for the default user and company names before falling back to the RegisteredXXX values. Fix the conformance test accordingly.

advapi32: Fix the AccessCheck tests so that the ACCESS_SYSTEM_SECURITY test now runs (when the user has the Security privilege).

Duplicate the token at SecurityImpersonation impersonation level instead
of SecurityIdentification, otherwise the call to RtlAdjustPrivilege
fails on Windows.

If HTTP_QUERY_CUSTOM is specified then the buffer contains a
null-terminated string on input and data of length len on output. The
code wasn't taking into account that the input len could be less than
the length of the string and thus could result in the allocated buffer
being overrun with the call to WideCharToMultiByte.

Adds support for D3D >= 8 style palettes that contain alpha. This fixes
rendering problems in games like Commandos 3 and Madden NFL 2004.

Slight rewrite to make creating additional D3D1 tests easier.
