This is not needed. setuid_rpc_client is trying to be very minimalistic

to have something small, thus auditable and yet capable of talking to
libvirtd through RPC.

Oops. You need to install cppi ;-)
The same problem is in 2/4.

You need to invent a new section to src/libvirt_private.syms so that
this symbol is correctly exported.
The rest of the patches looks okay.
