ntdll: Add prototypes to winnt.h for the SList functions.

[Francois Gouget]

Fix the implementation to match the official prototypes.

I've had trouble with the placement of 'volatile' in 'const 
SLIST_HEADER* volatile'. I think putting 'volatile' last is correct 
because it applies to the pointer, not to the pointed-to data like 
'const'.
