How hard would it be to modularize the libspice-server side?  The part
of the library that is used by QXL rendering should have much fewer
dependencies than the part that is used for keyboard, mouse, audio,
vmchannel/agent, etc.

Then you could link libspice-server-core into QEMU and libspice-server
into the modules.  Unless both have been linked together, functions such
as spice_server_add_client would fail, and so would adding most of the
SPICE_INTERFACE_* interface kinds.
