advapi32: Stubs for GetNamedSecurityInfoEx (attempt 4)

[Paul Bryan Roberts]

Reference bug 14334 (WordPerfect Office 2002: Unable to Install)

Use of breakpoints in a debugger under WindowsTM has shown that 
GetNamedSecurityInfoExA is called during a normal installation.  From 
this we infer that some kind of implementation of this routine is 
necessary if the app in question is ever to install.  It has been 
determined empirically that a empty sub is sufficient.

This attempt has been written without reference to the previous attempts 
or to the piclist web site.  It takes on board feedback received and has 
done after study of carefully distilled precedent exposed at:

The patch provides a stub pair for the A and W forms of 
GetNamedSecurityInfoEx.  Prototypes in include/aclapi.h, implementations 
in advapi32/security.c and the whats-it-called in advapi32/advapi32.spec.

No reference to GetNamedSecurityInfoEx is to be found on the MSDN 
web-site:  the signature of these stubs is derived by splicing to 
together GetNamedSecurityInfo and GetSecurityInfoEx (as found in 
aclapi.h etc).
