Testing service/driver install via setupapi

[Paul Vriens]

Hi,

I'm looking into bug 12030 (http://bugs.winehq.org/show_bug.cgi?id=12030). The 
driver service is not installed by our InstallHinfSection function.

I'm first trying to come up with a test before even trying to do the 
implementation. The question I'm having is whether I should be doing the test 
with InstallHinfSection and/or SetupInstallServicesFromInfSection[Ex]?

The current setupapi tests only test InstallHinfSection. But in the end 
SetupInstallFromInfSection will be called from within InstallHinfSection.

Should I take the same approach for the services piece?. So,

1) Implement in SetupInstallServicesFromInfSection[Ex]
2) Test via InstallHinfSection
