qxl: make qxl_render_update async
RHBZ# 747011
Removes the last user of QXL_SYNC when using update drivers that use the
_ASYNC io ports.
The last user is qxl_render_update, it is called both by qxl_hw_update
which is the vga_hw_update_ptr passed to graphic_console_init, and by
qxl_hw_screen_dump.
At the same time the QXLRect area being passed to the red_worker thread
is passed as a copy, as part of the QXLCookie.
The implementation uses interface_update_area_complete with a bh to make
sure dpy_update and qxl_flip are called from the io thread, otherwise
the vga->ds->surface.data can change under our feet.
With this patch sdl+spice works fine. But spice by itself doesn't
produce the expected screendumps unless repeated a few times, due to
ppm_save being called before update_area (rendering done in spice server
thread) having a chance to complete. Fixed by next patch, but see commit
message for problem introduced by it.
