Postpone stopping the dirty log to the point where the command fifo is
configured to allow drivers which don't use the fifo to work too.
(Without this the picture rendered into the vram never got to the
screen and the DIRECT_VRAM option meant to support this case was
removed a year ago.)

With both text (curses) and graphics (vnc/sdl/spice/...) display active
vga text mode emulation fails to update both correctly. Depending on
whenever vga_update_text() or vga_draw_text() happens to be called first
only the text display or only the graphics display will see display
resolution changes and full redraws.
Fix it by calling both text/gfx resize functions in both code paths and
keep track of full screen redraws needed in VGACommonState fields.

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,
standards conformant hwaddr.
Outstanding patchsets can be fixed up with the command
git rebase -i --exec 'find -name "*.[ch]"

Zap the global VGA_RAM_SIZE #define, make the vga ram size configurable
for standard vga and vmware vga. cirrus and qxl are left with a fixed
size (and private VGA_RAM_SIZE #define) for now.
qxl needs some non-trivial adjustments in the mode list handling deal
with a runtime-configurable size, which calls for a separate qxl patch.
cirrus emulates cards which have 2 MB (isa) and 4 MB (pci), so I guess
it would make sense to use these sizes. That change would break
migration though, so I left it fixed at 8 MB size. Making it
configurabls is pretty pointless for cirrus as we have to match real
hardware.

The vgabios will check whenever any given video mode will fit into the
given video memory before adding it to the list of available modes, so
there is no need to keep xmax * ymax * 32bpp lower than VGA_RAM_SIZE.
Lets raise the limits a bit. Should be good for a few years, display
sizes are not growing that fast.

With pc-0.12, we map the video RAM both through the PCI BAR (the guest does
this) and through a fixed mapping at 0xe0000000. The memory API doesn't allow
this double map, and aborts.
Fix by using an alias.

Most VGA memory access modes require MMIO handling as they demand weird
logic to get a byte from or into the video RAM. However, there is one
exception: chain 4 mode with all memory planes enabled for writing. This
mode actually allows lineary mapping, which can then be combined with
dirty logging to accelerate KVM.
This patch accelerates specifically VBE accesses like they are used by
grub in graphical mode. Not only the standard VGA adapter benefits from
this, also vmware and spice in VGA mode.

Convert all vga memory to the memory API. Note we need to fall back to
get_system_memory(), since the various buses don't pass the vga window
as a memory region.
We no longer need to sync the dirty bitmap of the cirrus mapped memory
banks, since the memory API takes care of that for us.

qxl is a paravirtual graphics card. The qxl device is the bridge
between the guest and the spice server (aka libspice-server). The
spice server will send the rendering commands to the spice client, which
will actually render them.
The spice server is also able to render locally, which is done in case
the guest wants read something from video memory. Local rendering is
also used to support display over vnc and sdl.
qxl is activated using "-vga qxl". qxl supports multihead, additional
cards can be added via '-device qxl".

This patch enables dirty log tracking whenever it's needed and disables it
when it is not.
We unconditionally enable dirty log tracking on reset, restart dirty log
tracking when PCI IO regions are remapped, and disable/enable it based on
commands from the guest.

Apparently, VBE maps the VGA vram to a fixed physical location. KVM requires
that all mappings of the VGA vram have dirty tracking enabled on them. Any
access to the VGA vram through the VBE mapping currently fails to result in
dirty page tracking updates causing a black screen.
This is the true root cause of VMware VGA not working correctly under KVM and
likely also an issue with some of the std-vga black screen issues too.
Cirrus does not enable VBE so it would not be a problem when using Cirrus.

The naming convention is goofy and it causes a massive merge problem. Something

All VGA devices share a common field subset; currently they do so by
a macro which defines the common fields inline their state structures,
relying on the the common state being placed at offset 0 in the structure.
This makes refactoring the code difficult and requires a lot of error prone
casts.
Replace the macro by a new VGACommonState structure, and the casts by
regular field access and container_of() for upcasts.

In theory, there are no more quirks in the KVM slot management that
requires dirty log start/stop all over the place. We just have to start
the logging each time the mapping may have changed. This patch drops
vga_dirty_log_stop for both standard and cirrus VGA. It also reverts
#6851 as it was obviously a tribute to the old slot system.
