[ros-diffs] [ion] 18097: Open BNO directory with correct privileges, open CSR connection with correct path. Add InWindows boolean to use the right CSR ServerID in windows and add a hack to get kernel32 to be loadable if used with .local to force an application to use our kernel and not the system one. The result of this is that our kernel32 can now load in Windows XP (not 2000).

Open BNO directory with correct privileges, open CSR connection with
correct path. Add InWindows boolean to use the right CSR ServerID in
windows and add a hack to get kernel32 to be loadable if used with
.local to force an application to use our kernel and not the system one.
The result of this is that our kernel32 can now load in Windows XP (not
2000).
