  console: skip same-size resize

virtio-gpu does a set-scanout at each frame (it might be a driver
regression). qemu_console_resize() recreate a surface even if the size
didn't change, and this shows up in profiling reports because the
surface is cleared. With this patch, I get a +15-20% glmark2
improvement.

  console: track gl_block state in QemuConsole

Keep track of gl_block state (added in bba19b8 console: block rendering
until client is done) in QemuConsole and allow to query it.  This way
we can avoid state inconsistencies in case different code paths make use
of this.

  spice/gl: render DisplaySurface via opengl

This switches over spice (in opengl mode) to render DisplaySurface
updates into a opengl texture, using the helper functions in
ui/console-gl.c.  With this patch applied spice (with gl=on) will
stop using qxl rendering ops, it will use dma-buf passing all the
time, i.e. for bios/bootloader (before virtio-gpu driver is loaded)
too.

This should improve performance even using spice (with gl=on) with
non-accelerated stdvga because we stop squeezing all display updates
through a unix/tcp socket and basically using a shared memory transport
instead.

  ui/vnc-enc-tight: remove switch and have single return

When enabling the sanitizer build it will complain about control
reaching a non-void function. Normally the compiler should detect that
there is only one possible exit given a static VNC_SERVER_FB_BYTES.

As we always expect a static VNC_SERVER_FB_BYTES I've added a compile
time assert and just called the sub-function directly.
