generic/062 has been written with assumption that user.* xattrs will fail on symlinks and special files. On newer kernel this will not be true. Found it very hard to modify generic/062 so that it can deal with both the possibilities. So creating a new test which basically is same as 062. Only difference is that it runs only if user.* xattrs can be set on symlinks and special files. Given this test is more or less same as 062, I have retained original copyright as well. Modified the test slightly to bail out if kernel is older and user xattrs are not supposed to be set on symlinks and special files. This patch will need little modification if corresponding kernel changes are merged upstream.
