kunit: add support for named resources
The kunit resources API allows for custom initialization and cleanup code (init/fini); here a new resource add function sets the "struct kunit_resource" "name" field, and calls the standard add function. Having a simple way to name resources is useful in cases such as multithreaded tests where a set of resources are shared among threads; a pointer to the "struct kunit *" test state then is all that is needed to retrieve and use named resources. Support is provided to add, find and destroy named resources; the latter two are simply wrappers that use a "match-by-name" callback. If an attempt to add a resource with a name that already exists is made kunit_add_named_resource() will return -EEXIST.
