[PATCH] netdev - udevdb+dev.d changes

Here is a patch to change the netdev handling in the database and for
the dev.d/ calls. I applies on top of the udevd.patch, cause klibc has
no sysinfo().

 o netdev's are also put into our database now. I want this for the
   udevruler gui to get a list of all handled devices.
   All devices in the db are stamped with the system uptime value at
   the creation time. 'udevinfo -d' prints it.

 o the DEVPATH value is the key for udevdb, but if we rename
   a netdev, the name is replaced in the kernel, so we add
   the changed name to the db to match with the remove event.

   NOTE: The dev.d/ scripts still get the original name from the
   hotplug call. Should we replace DEVPATH with the new name too?

 o We now only add a device to the db, if we have successfully created
   the main node or successfully renamed a netdev. This is the main part
   of the patch, cause I needed to clean the retval passing trough all
   the functions used for node creation.

 o DEVNODE sounds a bit ugly for netdev's so I exported DEVNAME too.
   Can we change the name?

 o I've added a UDEV_NO_DEVD to possibly skip the script execution
   and used it in udev-test.pl.
   udevstart is the same horror now, if you have scripts with logging
   statements in dev.d/ it takes minutes to finish, can we skip the
   scripts here too?

 o The get_device_type() function is changed to be more strict, cause
   'udevinfo -a -p /block/' gets a class device for it and tries to
   print the major/minor values.

 o bugfix, the RESULT value has now a working newline removal and a test
   for this case.
