console: add same surface replace pre-condition
Catch an invalid state early, before a potential use-after-free. This is
mainly useful for documentation purposes.

memory: add support getting and using a dirty bitmap copy.
This patch adds support for getting and using a local copy of the dirty
bitmap.
memory_region_snapshot_and_clear_dirty() will create a snapshot of the
dirty bitmap for the specified range, clear the dirty bitmap and return
the copy. The returned bitmap can be a bit larger than requested, the
range is expanded so the code can copy unsigned longs from the bitmap
and avoid atomic bit update operations.
memory_region_snapshot_get_dirty() will return the dirty status of
pages, pretty much like memory_region_get_dirty(), but using the copy
returned by memory_region_copy_and_clear_dirty().

-----------
vga: add vga_scanline_invalidated helper
Add vga_scanline_invalidated helper to check whenever a scanline was
invalidated. Add a sanity check to fix OOB read access for display
heights larger than 2048.
Only cirrus uses this, for hardware cursor rendering, so having this
work properly for the first 2048 scanlines only shouldn't be a problem
as the cirrus can't handle large resolutions anyway. Also changing the
invalidated_y_table size would break live migration.

vga: make display updates thread safe.
The vga code clears the dirty bits *after* reading the framebuffer
memory. So if the guest framebuffer updates hits the race window
between vga reading the framebuffer and vga clearing the dirty bits
vga will miss that update
Fix it by using the new memory_region_copy_and_clear_dirty()
memory_region_copy_get_dirty() functions. That way we clear the
dirty bitmap before reading the framebuffer. Any guest display
updates happening in parallel will be properly tracked in the
dirty bitmap then and the next display refresh will pick them up.
Problem triggers with mttcg only. Before mttcg was merged tcg
never ran in parallel to vga emulation. Using kvm will hide the
problem too, due to qemu operating on a userspace copy of the
kernel's dirty bitmap.

Fix standard vga mode check: Both s->config and s->enabled must be set
to enable vmware command fifo processing.
Drop dirty tracking code from the fifo rendering code path, it isn't
used anyway because vmsvga turns off dirty tracking when leaving
standard vga mode.

qxl: add xres and yres properties
Add properties for the default display resolution, pass
on that information to the guest so the driver can use it.
Also move up qxl_crc32() function so we don't need a
forward declaration.
Additionally guest driver updates are needed so the
guest driver will actually pick this up, which will
probably land in linux kernel 4.12.
