PATCH: Usetup - Getting rid of some indirection

Created an attachment (id=4708)
Indirection patch for revision 45654

In usetup.c and a few related files there where many calls to methods in inffile.c which simply called another function with the same signature. In this patch I attempted to move things around so that the functions where called directly rather than going through inffile.c. I think the original thinking for the old way was to keep related functions in the same infros.h file which were not referenced in usetup.h. I tried my best to assure similar functionality and eliminate causes for errors though my view was limited so I could have missed some things. Limitations were due to using the usetup solution instead of the all encompassing one(which takes a long time to load) and the number of errors that show up in Microsoft Visual Studio reaching the limit before showing anything related to the files I was working on.
