[PATCH] kobject: add add_hotplug_env_var()
Add a (non-inlined) add_hotplug_env_var() function to <linux/kobject.h>
and lib/kobject.c. There's a lot of boilerplate code involved in
setting environment variables in a hotplug method, so we should have a
convenience function to consolidate it (and avoid subtle bugs).
