declarations of functions for setting and getting a node ID number, a functionality that exists on many platforms. Since this functionality was not considered part of the Contiki core, each platform defined its own node-id.h file. This commit attempts to clean this up by collecting the node-id.h into a core/sys/node-id.h file that replaces the old node-id.h files from the platform directories.
