wined3d: Flip the coordinate system rather than the coordinates itself for onscreen surfaces in stretch_rect_fbo.

Implement SetupQueryInfOriginalFileInformationA on top of SetupQueryInfOriginalFileInformationW.

setupapi: The inf file containing the SourceDisksFiles and SourceDisksNames sections is the same as hinf if there is no layout file specified.

So pass the correct inf handle to SetupQueueDefaultCopyW and SetupQueueCopySectionW.

hhctrl.ocx: Update HtmlHelp and its commands definitions, and partially implement data A->W translation.

The TEXT_TabbedTextOut didn't set correctly the text starting point
(x0) for left-aligned tabs and was ignoring the last tab. I've also
changed GetTextMetricsA to W as this should be slightly faster.
