Removed the object-table function macros from each demo object header file since it was very difficult to maintain when new functions are added. Added device-client.c file which is a small device object just for simple clients. Updated most Makefiles of client demo applications to utilize device-client.c file.

Added two device object table functions for COV support.
Corrected demo COV handler interaction with TSM, COV flags, and multiple subscriptions for the same object.
