conf: Introduce new <hostdev> attribute 'display' QEMU 2.12 introduced a new type of display for mediated devices using vfio-pci backend which allows a mediated device to be used as a VGA compatible device as an alternative to an emulated video device. QEMU exposes this feature via a vfio device property 'display' with supported values 'on/off/auto' (libvirt will default to 'off'). This patch adds the necessary bits to domain config handling in order to expose this feature. Since there's no convenient way for libvirt to come up with usable defaults for the display setting, simply because libvirt is not able to figure out which of the display implementations - dma-buf which requires OpenGL support vs vfio regions which doesn't need OpenGL (works with OpenGL enabled too) - the underlying mdev uses.

tests: fix name of 32-bit x86 QEMU binary The 32-bit x86 binary is called qemu-system-i386, not qemu-system-i686. This mistake across many test XML files was not noticed because the mistake was also made in testutilsqemu.c when mocking the capabilities.

qemu: populate <audio> element with default config Currently the QEMU driver secretly sets the QEMU_AUDIO_DRV env variable - VNC - set to "none", unless passthrough of host env variable is set - SPICE - always set to "spice" - SDL - always passthrough host env - No graphics - set to "none", unless passthrough of host env variable is set The setting of the QEMU_AUDIO_DRV env variable is done in the code which configures graphics. If no <audio> element is present, we now auto-populate <audio> elements to reflect this historical default config. This avoids need to set audio env when processing graphics.
