* move prototype defined in patch 1 but used in patch 2 to patch 2.
(qxl_vga_mode_get_command)
This patchset removes all uses of unlock/lock in qxl and spice code.
It does this by reimplementing the one path that required a lock from the
spice-server thread, namely interface_get_command when in vga mode or running
without a qxl device.
Incidentaly it fixes the assert(cpu_single_env) that happen in the unrelated
qemu-kvm repository, because we never drop the global lock in io vmexits.
Tested with winxp 32 bit and linux 64 bit vms, including changes between vga
mode and qxl mode using chvt. Also tested -sdl and -vnc together with -spice.
