The syscall l4_task_cap_equal almost returns false although the referenced kernel-objects are equal. This patch changes the semantic of the syscall so that whenever two capabilities refering the same kernel-object are compared it will return true. Please refer to the discussion of the following mail thread: http://www.mail-archive.com/l4-hackers@os.inf.tu-dresden.de/msg05162.html
