[Qemu-devel] [RFC][PATCH 10/10] virtproxy: add compat defs for linking against vl.c

[Michael Roth <mdroth@linux.vnet.ibm.com>]

Virtagent depends on basic qemu functions re-implemented by qemu-vp to
allow it to be used in output of qemu (in particular, to allow the
client code to be used for guest-to-host RPC calls). To build virtagent
into qemu we need to define these in terms of the built-in qemu
functions.
