I would suggest not to spend the spares in the main branch.
So this commit should add the field, keeping 8 spares. But
the merge to stable/14 should use a spare.

Otherwise we eventually will run out of spares in main
and also nearly run out of spares in some stable/22 branch.

I'd suggest to follow the policy of not spending spares
in the main branch for all structures, not just xsocket.
