Subject: [PATCH] Rewrite isWriteModeEnabled() with API

This also introduces a slight behavioral change: Previously, only the
core file with the "raised" io desc was checked, which is RzIO.desc. But
that member is deprecated for good reasons, so now we just check if
there is any core file whose primary fd has write enabled.
