Also removes now redundant setting of vidmem flag on rendertargets, prevents 
adding vidmem flag when sysmem flag is present. Fixes missing textures in Forsaken.

comctl32: statusbar: Rename NtfUnicode to bUnicode to make is more consistent with other controls, use NF_REQUERY in WM_CREATE.

comctl32: statusbar: Window is always Unicode, CCM_SETUNICODEFORMAT should change the notify format.

This patch enables texture filtering for textures using the A4R4G4B4
format, I can see no reason why it shouldn't be filtered (especially
considering X4R4G4B4 has it).

The regression was caused by destroying the caret when it didn't need to
be shown in the richedit control, but this affected other controls.

rpcrt4: Fix the memory pointer passed into the conformant array marshaller in NdrComplexStructMarshall.

It needs to be the end of the memory used by the constant part of the
structure, which is returned by CompkexStructMarshall.

wined3d: Use rev_tex_unit_map instead of assuming there's a 1:1 mapping between samplers and texture units.
