console: add support for dmabufs

This patch adds support for dma-bufs to the qemu console interfaces.
It adds a new "struct QemuDmaBuf" to represent a dmabuf with accociated
metatdata (size, format).  It adds three functions (and
DisplayChangeListenerOps operations) to set a dma-buf as display
scanout, as cursor and to release a dmabuf.
