+Subject: [PATCH] Remove ThreadPool.h inclusion in upnpdebug.h
+
+ThreadPool.h is now a private header which is not installed so remove
+this header from upnpdebug.h otherwise an external application which
+includes upnpdebug.h will crash
+
+Also add LinkedList.h to service_table.h as it was included by
+ThreadPool.h in upnpdebug.h
