In xlnx_dp_aux_set_command, when the command leads to the default
branch, xlxn-dp will abort and then crash.
This patch removes this abort and drops this operation.

When in CGA modes, QEMU wants to ignore the maximum scan field (bits 0..4) of
the maximum scan length register in the CRTC. It is not clear why this is
needed---for example, Bochs ignores bit 7 instead. The issue is that the
CGA modes are not detected correctly, and in particular mode 6 results in
multi_scan==3 according to how SeaBIOS programs it. The right way to check
for CGA graphics modes is to check whether bit 13 of the address is special
cased by the CRT controller to achieve line interleaving, i.e. whether bit 0
of the CRTC mode control register is clear.

This patch fixes the dedicated framebuffer mailbox interface by
removing an unneeded offset. This means that we pick the framebuffer
address in the same way that we do if the guest code uses the buffer
allocate mechanism of the bcm2835_property interface (case
0x00040001: /* Allocate buffer */ in bcm2835_property.c).
The documentation of this mailbox interface doesn't say anything
about using parts of the request buffer address to affect the
chosen framebuffer address:
https://github.com/raspberrypi/firmware/wiki/Mailbox-framebuffer-interface
Some baremetal applications like the Screen01/Screen02 examples from
Baking Pi tutorial[1] didn't work before this patch.

Add an asynchronous version of i2c_send() that requires the slave to
explicitly acknowledge on the bus with i2c_ack().
The current master must use the new i2c_start_send_async() to indicate
that it wants to do an asynchronous transfer. This allows the i2c core
to check if the target slave supports this or not. This approach relies
on adding a new enum i2c_event member, which is why a bunch of other
devices needs changes in their event handling switches.

This change adds a new member, refresh_rate to QemuUIInfo in
include/ui/console.h. It represents the refresh rate of the
physical display backend, and it is more appropriate than
GUI update interval as the refresh rate which the emulated device
reports:
- sdl may set GUI update interval shorter than the refresh rate
of the physical display to respond to user-generated events.
- sdl and vnc aggressively changes GUI update interval, but
a guests is typically not designed to respond to frequent
refresh rate changes, or frequent "display mode" changes in
general. The frequency of refresh rate changes of the physical
display backend matches better to the guest's expectation.
QemuUIInfo also has other members representing "display mode",
which makes it suitable for refresh rate representation. It has
a throttling of update notifications, and prevents frequent changes
of the display mode.

whenever that module depends on the Kconfig to be enabled.
When the module is enabled in Kconfig we are sure that its dependencies
will be enabled as well, thus the module will be loaded without any
problem.
The correct way to use module_kconfig is by passing the Kconfig option
to module_kconfig (or the *config-devices.mak without CONFIG_).

The framebuffer_update_display() function returns the dirty scanlines that were
touched since the last display update, however artist_update_display() always calls
dpy_gfx_update() with start and end scanlines of 0 and s->height causing the
entire display surface to be rendered on every update.
Update artist_update_display() so that dpy_gfx_update() only renders the dirty
scanlines on the display surface, bypassing the display surface rendering
completely if framebuffer_update_display() indicates no changes occurred.
This noticeably improves boot performance when the framebuffer is enabled on my
rather modest laptop here, including making the GTK UI usable.

In certain circumstances, typically when there is lots changing on the
screen, updates will be discarded resulting in garbled output.
This change simplifies the traversal of the display update FIFO queue
when applying updates. We just track the queue length and iterate up to
the end of the queue.
Additionally when adding updates to the queue, if the buffer reaches
capacity we force a flush before accepting further events.

One less qemu-specific macro. It also helps to make some headers/units
only depend on glib, and thus moved in standalone projects eventually.

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

QEMU currently abort()s if the user tries to add a second ISA VGA
device, for example:
$ ./qemu-system-x86_64 -device isa-vga -device isa-vga
RAMBlock "vga.vram" already registered, abort!
Aborted (core dumped)
$ ./qemu-system-x86_64 -device isa-cirrus-vga -device isa-cirrus-vga
RAMBlock "vga.vram" already registered, abort!
Aborted (core dumped)
$ ./qemu-system-mips64el -M pica61 -device isa-vga
RAMBlock "vga.vram" already registered, abort!
Aborted (core dumped)
Such a crash should never happen just because of giving bad parameters
at the command line. Let's return a proper error message instead.
(The idea is based on an original patch by Jose R. Ziviani for the
isa-vga device, but this now fixes it for the isa-cirrus-vga device, too)

The vga_common_init() function currently cannot report errors to its
caller. But in the following patch, we'd need this possibility, so
let's change it to take an "Error **" as parameter for this.

Most of the code in this function had been indented with 5 spaces instead
of 4. Since 4 is our preferred style, remove one space in the bad lines here.

If booting Linux directly in the q800 machine using -kernel rather than using a
MacOS toolbox ROM, the mode control registers are never initialised,
causing macfb_mode_write() to fail to determine the current resolution after
migration. Resolve this by always setting the initial values of the mode control
registers based upon the initial macfb properties during realize.

These fields are required in the migration stream to restore macfb state
correctly.
Note this is a migration break, but since there are upcoming incompatible changes
for the q800 machine (and migration does not even succeed without these patches)
then this is not an issue.

The MacOS toolbox ROM accesses a number of addresses between 0x0 and 0x200 during
initialisation and resolution changes. Whilst the function of many of these
registers is unknown, it is worth the minimal cost of saving these extra values as
part of migration to help future-proof the migration stream for the q800 machine
as it starts to stabilise.

Currently when QEMU tries to migrate the macfb framebuffer it crashes randomly
because the opaque provided by the DeviceClass vmsd property for both devices
is set to MacfbState rather than MacfbNubusState or MacfbSysBusState as
appropriate.
Resolve the issue by adding new VMStateDescriptions for MacfbNubusState and
MacfbSysBusState which embed the existing vmstate_macfb VMStateDescription
within them using VMSTATE_STRUCT.

Many files use "qemu/log.h" declarations but neglect to include
it (they inherit it via "exec/exec-all.h"). "exec/exec-all.h" is
a core component and shouldn't be used that way. Move the
"qemu/log.h" inclusion locally to each unit requiring it.
