description:
Convert EV_SET(2) back into macro again

This retains compatibility with other moder BSDs if someone uses:
"#ifdef EV_SET".

This code also casts the last parameter to intptr_t, as other BSDs keep
this argument with a different type void*.

This change renames function EV_SET to EV_SET_, and calls it from EV_SET().
