Xen devel - Oct 2006 - [BUGFIX][ACM][Resource Labels] This patch fixes problems with multiple representations of the same labeled resource

This patch fixes problems with resource representations in the 
resource_label file. Without this patch, multiple representations of the 
same resource can co-exist in the resource label file and lead to errors 
during operation.

This patch ensures that all resource file names are stored with absolute 
path name and are unique. Setting labels of phy-resources, relative 
paths will automatically be pre-pended with ''/dev/''; labeling 
file-resources with relative paths will raise an error.

This patch is tested successfully both manually, with ACM=n and xm-test, 
and with ACM=y and xm-test (using our pending ACM extensions to xm-test).

Thanks
Reiner
