Initialize functions used to handle messages

/* initialize functions for handling messages */
iofunc_func_init(_RESMGR_CONNECT_NFUNCS, &connect_funcs, 
                 _RESMGR_IO_NFUNCS, &io_funcs);

Here we supply two tables that specify which function to call when a particular message arrives:

• connect functions table
• I/O functions table

Instead of filling in these tables manually, we call iofunc_func_init() to place the iofunc_*_default() handler functions into the appropriate spots.
