[Devel] [PATCH][NET-2.6.25] Move sock_valbool_flag to socket.c

[Pavel Emelyanov]

The sock_valbool_flag() helper is used in setsockopt to 
set or reset some flag on the sock. This helper is required
in the net/socket.c only, so move it there.

Besides, patch two places in sys_setsockopt() that repeat
this helper functionality manually.

Since this is not a bugfix, but a trivial cleanup, I
prepared this patch against net-2.6.25, but it also
applies (with a single offset) to the latest net-2.6.
