+ * Create new udev device, and fill in information from the sys

+ * by a special string:
+ * b8:2 - block device major:minor
+ * c128:1 - char device major:minor
+ * n3 - network device ifindex
+ * +sound:card29 - kernel driver core subsystem:device name
+ *
+ * The initial refcount is 1, and needs to be decremented to
+ * release the resources of the udev device.

+ * Returns: a new udev device, or #NULL, if it does not exist
