kobject: remove the static array for the name
Due to historical reasons, struct kobject contained a static array for
the name, and a dynamic pointer in case the name got bigger than the
array. That's just dumb, as people didn't always know which variable to
reference, even with the accessor for the kobject name.
This patch removes the static array, potentially saving a lot of memory
as the majority of kobjects do not have a very long name.
Thanks to Kay for the idea to do this.
