Here's the patch applying the latest libsysfs.
- adds the latest libsysfs code to udev
* new code includes dlist implementation, a generic linked list
implementation. Needed our own because LGPL
* rearranged structures
* provided more functions for accessing directory and attributes
- gets rid of ->directory->path references in namedev.c
- replaces sysfs_get_value_from_attributes with sysfs_get_classdev_attr
