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.
