DDraw can draw to the front buffer only, thus there's never a Present
call which could pass this window. Due to that a drawing-independent
method is needed.

This is a long-needed cleanup aimed at removing the ddraw_primary,
ddraw_window, ddraw_width and ddraw_height members from
IWineD3DDeviceImpl, which just do not belong there.  Destination
window and screen handling is supposed to be done by swapchains.

It's needed by DispatchEx implementation.

RPC_FC_ERROR_STATUS_T has a value of 0x10 and therefore isn't a
possible value of "flags_type & 0xf" in the switch statement.

header isn't a string and therefore using strncmp doesn't make sense.

It's the number of elements, not the number of bytes.

shell32: Don't assign a result from a function that returns a BOOL to an HRESULT in shellex_get_dataobj.

Otherwise there could be confusion as to what type GetFullPathNameW is
returning.

This makes it more obvious what the code is doing.

msrle32: Fix uses of arithmetic operators on Boolean types in MSRLE32_CompressRLE4Line and MSRLE32_CompressRLE8Line.

The "extra_byte" variable is used as though it contains an integer
rather than a TRUE/FALSE value so make it into an integer.

Use a conditional operator to get the same result, but improving
readability of the code.

Also compare the result of IOleObject_QueryInterface with S_OK instead
of using not operator so it is more clear what the code is doing.
