[PATCH] udev - safer string handling - part four

[PATCH] udev - safer string handling - part four

Mainly a cleanup of the earlier patches with a few missing pieces
and some cosmetical changes.

I've moved the udev_init_config() to very early init, otherwise we
don't get any logging for the processing of the input. What would I
do without gdb :)

Greg, it's the 7th patch in your box to apply. I will stop now and
wait for you :)
