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.

Self NACK, some errors in this patchset, sending v2 with cleanup
(qxl_cookie_new to reduce the duplicate code).

RHBZ# 794658
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, allocated and copied before passing, deallocated on
the interface_async_complete callback.

We still have spice_qxl_flush_surfaces_async(&qxl->ssd.qxl, 0);
So cookie might be NULL in this case.

I don't know if it's prohibited in qemu code, but g_slice would be a
good fit here: frequently allocated bits of same size.

Hmm, why that? If the callers want a cookie, then they should
explicitly pass in what they want instead of expecting the function to
magically do the correct thing. If the callers don't need a cookie,
then use something like QXL_COOKIE_TYPE_UNUSED or simply pass on the
NULL pointer.
cheers,
Gerd

NACK these two, Marc Andre found a cookie I missed, and the bz in the
commit message is a dup of an existing bug (747011).

I can move it to the users if it makes it a little less magic.
Note that I will be sending a revized version, since:
1) I forgot about my previous attempt (october 2010,
http://lists.gnu.org/archive/html/qemu-devel/2011-10/msg02758.html)
2) there are a few bugs with this approach, that I fixed correctly back
then: one is the async monitor command, which I will not send this time
since I don't want to get into the same argument.
3) the second is the dirty rectangles, for which I have to raise
SPICE_INTERFACE_QXL_MINOR.
