get rid of duplicate logics in __SC_....[1-6] definitions
All those guys have the same form - "take a list of type/name pairs, apply some macro to each of them". Abstract that part away, convert all __SC_FOO##x(__VA_ARGS__) to __MAP(x,__SC_FOO,__VA_ARGS__). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
