[Qemu-devel] [PATCH for-2.7 v3 07/12] spice: Initialization stubs on qemu-spice.h

[Eduardo Habkost <ehabkost@redhat.com>]

This reduces the number of CONFIG_SPICE #ifdefs in vl.c.

Changes v1 -> v2:
* Move stubs to qemu-spice.h, as the header file already
  had a separate section for !CONFIG_SPICE
