Resolves: bug 237356

Description: Move DS Admin Code into Admin Server - Inf, ds_newinst.pl
Fix Description: Some minor cleanup:
1) Setup must not write to the user supplied inf file.  Setup uses the user supplied inf to initialize its cache, but creates a tempfile for writing.
2) When writing an Inf, preserve the continuation lines.
3) Added Noriko's fix for suffix generation to ds_newinst.pl
Platforms tested: RHEL4
Flag Day: No.
Doc impact: No.
