* \param id identifier to distinguish multiple calls to 'fn'

* The initcall function must comply 'int func(void)'.
* The marked function is exported via a non-static symbol called
* "dde_kit_initcall_<id>_<fn>". On driver startup, the driver environment has
* to explicitly call these functions.
*
* This is the right mechanism to mark, e.g., Linux module_init() functions.
