Subject: [PATCH] libutil: make Fd{Sink,Source} io buffer shareable

we will need this during RemoteStore wire asyncification to be able to
use the old synchronous serializers. alternatively we could define all
serializers on the async types as well, but that'd be slow and far too
much unnecessarily duplicated code (that will be deleted soon anyway).
