container_of: add container_of_const() that preserves const-ness of the pointer
container_of does not preserve the const-ness of a pointer that is
passed into it, which can cause C code that passes in a const pointer to
get a pointer back that is not const and then scribble all over the data
in it. To prevent this, container_of_const() will preserve the const
status of the pointer passed into it using the newly available _Generic()
method.
