[PATCH] udevstart: simplify "dev" file searching

Just stat() the "dev" file in the device directory instead of
opening the directory and iterating over all entries.

Make udevstart work with the settings in with udev.conf so we can
run a test program.

Add a test for udevstart.

Remove changelog stuff from code. We should never start with this
silly thing.
