include isc/region.h and new omapi/types.h typedefs moved to omapi/types.h define protocol port to 7912 so as not to conflict with dhcp server; this clearly needs more thought. the default omapi port will need to be server specific rather than library specific. new public functions, omapi_listener_shutdown, omapi_data_getint. changed API, omapi_string_totext, omapi_value_getint
