ui/gtk: gd_draw_event returns FALSE when no cairo surface is bound
ui/gtk-egl: guest fb texture needs to be regenerated when reinitializing egl
ui/gtk-egl: make sure the right context is set as the current

virtio-gpu: splitting one extended mode guest fb into n-scanouts

When guest is running Linux/X11 with extended multiple displays mode enabled,
the guest shares one scanout resource each time containing whole surface
rather than sharing individual display output separately. This extended frame
is properly splited and rendered on the corresponding scanout surfaces but
not in case of blob-resource (zero copy).

This code change lets the qemu split this one large surface data into multiple
in case of blob-resource as well so that each sub frame then can be blitted
properly to each scanout.

v2: resizing qemu console in virtio_gpu_update_dmabuf to scanout's width and
height

v3: updating stub function of virtio_gpu_update_dmabuf to match the type

hw/display: Restrict virtio-gpu-udmabuf stubs to !Linux

When using qemu configured with --enabled-modules, the
generic stubs are used instead of the module symbols:

qemu-system-x86_64: -device vi

hw/display: Restrict virtio-gpu-udmabuf stubs to !Linux

When using qemu configured with --enabled-modules, the
generic stubs are used instead of the module symbols:

qemu-system-x86_64: -device virtio-vga,blob=on: cannot enable blob resources without udmabuf

Restrict the stubs to Linux and only link them when
CONFIG_VIRTIO_GPU is disabled (only the modularized
version is available when it is enabled).
