It's looking better now, thanks. I realize that this is a bit onerous, but to maximize the chances of this code being accepted, it should be split into three separate commits:
1. Add SLLoadApplicationPolicies stub. 2. Add SLGetApplicationPolicy stub. 3. Sleep forever in SLOpen.
You may already be a Git expert, but if not, you may find that `git reset HEAD^` and `git add -p` are helpful for redoing a commit as multiple commits.
Patches 1 and 2 will hopefully not be controversial. I still don't know what others are going to think of patch 3. If it is not considered acceptable for mainline Wine, please submit it to [Wine Staging](https://gitlab.winehq.org/wine/wine-staging) instead; one of the goals of the Staging fork is to make things work in ways that would not be considered acceptable in mainline Wine.
