LSA Patch for User Manager

LSA Patch for User Manager

New (major) patch
=================
- Enhances the "lsa.idl" file in the sense that it adds more values to
"PolicyInformation" to improve the "lsa_QueryInfoPolicy*" calls.
- Adds a minimal implementation for "AuditEvents" (also lsa_QueryInfoPolicy*
calls) to enable the "Audit" option in the "User Manager for Domains" (at least
readable).
- Adds to the "lsa.idl" file the system access mode flags needed for the calls
"lsa_*SystemAccessAccount".
- Fill in the "lsa_GetSystemAccessAccount" for enabling the "User Rights"
option in the "User Manager for Domains" (at least readable).
- Merge the two similar torture tests of the "lsa_QueryInfoPolicy*" calls in
one using "if"'s for a few separations.
- Add a torture test for "lsa_GetSystemAccessAccount".
- Some cosmetic-only changes (unifications) in output strings in the "LSA"
torture test.

The work has been done using the Microsoft WSPP docs.
