[PATCH] add udev-test perl script from Kay Sievers <kay.sievers@vrfy.org> which blows away my puny shell scripts.

+# udev-test
+#
+# Provides automated testing of the udev binary.
+# The whole test is self contained in this file, except the matching sysfs tree.
+# Simply extend the @tests array, to add a new test variant.
+#
+# Every test is driven by its own temporary config file.
+# This program prepares the environment, creates the config and calls udev.
+#
+# udev reads the config, looks at the provided sysfs and
+# first creates and then removes the device node.
+# After creation and removal the result is checked against the
+# expected value and the result is printed.
+#
+# happy testing,
+# Kay Sievers <kay.sievers@vrfy.org>, 2003
