In an unexpected turn of events go1.24 reclassified import "C" non-local, which rendered C.blst_* type aliases defunct. The only working solution appears to be to wrap them into structs. Since all the C.blst_* types were opaque, the wrapping shouldn't affect applications. In the sense that the shell struct won't obstruct anything, because nothing was visible.
