cleanup: my_getopt, consistency

almost all my_getopt settings and callbacks are global variables,
directly assignable to configure my_getopt. Only getopt_get_addr
was using a setter function. Get rid of it, make it a global
directly assignable variable like all other settings.

Also make getopt_compare_strings() static.
