[ros-dev] Setupapi & VBox additions

[Thomas Faber]

Hi,

I've been looking at VirtualBox 4.1.x guest additions, which don't install
in ROS [1] and came up with a patch [2] that seems to fix them.

While patchbot says this is okay [3] (and the last hunk even fixes a few
setupapi tests), I am very unsure about the SP_COPY_NOOVERWRITE part.
The correct solution might instead be to handle SetupCopyOEMInf returning
ERROR_FILE_EXISTS or I might be "fixing" something in the completely
wrong place.

It would be great if someone with some insight into setupapi
(Eric? Hervé? ;]) could review this and give some pointers.

Thanks!

Patch explanation:
- The first hunk isn't really required, but I guess it shouldn't break
  anything, and seems to find what it's looking for this way.
- The second hunk is in the code path used by VBox guest additions setup.
  It is apparently called with an already-existing inf file, but I have
  no idea why. :|
- The third hunk is a trivial bug that our CreateService just didn't
  complain about before r53872/r53886
