[PATCH] udevd test script

Thanks to Yin, Hu <hu.yin@intel.com>, who made a nice perl script to test the
expected behavior of the udevd sequence number handling. The test sends
different SEQNUM sequences to udevd, while analyzing the reordering and timeout
handling of udevd.

+# This is a script for replacing udev binary during udevsend/udevd testing.
+# It first amplifies the execution time ( sleep 5 ) and then logs the event 
+# information sent by udved in order that test script udevd-test.pl can
+# analyze whether udved execute as we expected.
+# You should not execute this script directly because it will be invoked by 
+# udevd automatically.
+#
+# Before you run your test please modify $log_file to designate where the udev
+# log file should be placed, in fact, the default value is ok.
