[PATCH] udev - safer string handling - part three

Here we truncate our input strings from the environment to our
defined limit. It's a bit theroretical but better check for it.

It cleans up some magic length definitions and removes the code
duplication in udev, udevtest and udevsend.

udevd needs to be killed after installation, cause the message size
is changed with this patch.
Should we do this with the 'make install', like we do with the '.udevdb'?
