Hi,
This patch series brings some minor opengl bug fixes and also
some virtio-gpu preparations for spice support.
please review,
Gerd

Allow gl user interfaces to block display device gl rendering.
The ui code might want to do that in case it takes a little
longer to bring things to screen, for example because we'll
hand over a dma-buf to another process (spice will do that).

We'll go take out the commands we receive out of the virt queue and put
them into a linked list, to decouple virtio queue handling from actual
command processing.
Also move cmd processing to new virtio_gpu_handle_ctrl func, so we can
easily kick it from different places.

g_new0 is costly (the struct is big) and quite unnecessary here:

Add:

and you can switch to g_new.
