As we want qemu symbols be exported to modules we should use the
gmodule-export-2.0 pkg-config instead of gmodule-2.0.

QEMU's screendump command can only take dumps from the primary display.
When using multiple VGA cards, there is no way to get a dump from a
secondary card or other display heads yet. So let's add a 'device' and
a 'head' parameter to the HMP and QMP commands to be able to specify
alternative devices and heads with the screendump command, too.

Add support for cursor dmabufs. qemu has to render the cursor for
that, so in case a cursor is present qemu allocates a new dmabuf, blits
the scanout, blends in the pointer and passes on the new dmabuf to
spice-server. Without cursor qemu continues to simply pass on the
scanout dmabuf as-is.

Secondary displays in multihead setups are allowed to have a NULL
DisplaySurface. Typically user interfaces handle this by hiding the
window which shows the display in question.
This isn't an option for vnc though because it simply hasn't a concept
of windows or outputs. So handle the situation by showing a placeholder
DisplaySurface instead. Also check in console_select whenever a surface
is preset in the first place before requesting an update.
This fixes a segfault which can be triggered by switching to an unused
display (via vtrl-alt-<nr>) in a multihead setup, for example using
-device virtio-vga,max_outputs=2.

For dma-buf support we need a egl context. The gtk x11 backend uses glx
contexts though. We can't use the GtkGlArea widget on x11 because of
that, so use our own gtk-egl code instead. wayland continues to use
the GtkGlArea widget.

This patch disables the pragma diagnostic -Wunused-but-set-variable for
clang in util/coroutine-ucontext.c.
This in turn allows us to remove it from the configure check, so the
CONFIG_PRAGMA_DIAGNOSTIC_AVAILABLE will succeed for clang.
With that in place clang builds (linux) will use -Werror by default,
which breaks the build due to warning about unaligned struct members.
Just turning off this warning isn't a good idea as it indicates
portability problems. So make it a warning again, using
-Wno-error=address-of-packed-member. That way it doesn't break the
build but still shows up in the logs.
Now clang builds qemu without errors. Well, almost. There are some
left in the rdma code. Leaving that to the rdma people. All others can
use --disable-rdma to workarounds this.

There are 3 parts to this change:
- Add a comment showing the relative sizes and positions of the blocks of
memory
- introduce and use new aligned_{start,size} instead of adjusting
real_{start_size}
- When we clean up (on failure), munmap(real_start, real_size) instead of
munmap(aligned_start, aligned_size). It *shouldn't* make any
difference, but I will admit that this does mean we are making the
syscall with different values, so this isn't quite a no-op patch.

initialization
init_guest_commpage needs to check if the mapped space, which ends at
real_start+real_size overlaps with where it needs to put the commpage,
which is (assuming sane qemu_host_page_size) guest_base + 0xffff000, where
guest_base is real_start - guest_start.
[guest_base][ 0xffff0000 ][commpage]
[guest_base][guest_start][real_size] [commpage]
[ real_start ][real_size] [commpage]
^
fail if this gap < 0
Since init_guest_commpage wants to do everything relative to guest_base
(rather than real_start), it obviously needs to be comparing 0xffff0000
against guest_start+real_size, not just real_size.
This bug has been present since 806d102141b99d4f1e55a97d68b7ea8c8ba3129f in
2012, but guest_start is usually 0, and prior to v2.11 real_size was
usually much smaller than 0xffff0000, so it was uncommon for it to have
made a difference.

Instead of defining a bogus validate_guest_space that always returns 1 on

In linux-user QEMU that runs for a target with TARGET_ABI_BITS bigger
than L1_MAP_ADDR_SPACE_BITS an assertion in page_set_flags fires when
mmap, munmap, mprotect, mremap or shmat is called for an address outside
the guest address space. mmap and mprotect should return ENOMEM in such
case.
Change definition of GUEST_ADDR_MAX to always be the last valid guest
address. Account for this change in open_self_maps.
Add macro guest_addr_valid that verifies if the guest address is valid.
Add function guest_range_valid that verifies if address range is within
guest address space and does not wrap around. Use that macro in
mmap/munmap/mprotect/mremap/shmat for error checking.

From the "Physical Layer Simplified Specification Version 3.01":
A known data block ("Tuning block") can be used to tune sampling
point for tuning required hosts. [...]
This procedure gives the system optimal timing for each specific
host and card combination and compensates for static delays in
the timing budget including process, voltage and different PCB
loads and skews. [...]
Data block, carried by DAT[3:0], contains a pattern for tuning
sampling position to receive data on the CMD and DAT[3:0] line.
[based on a patch from Alistair Francis <alistair.francis@xilinx.com>
from qemu/xilinx tag xilinx-v2015.2]

Add support for passing 'max' to -machine gic-version. By analogy
with the -cpu max option, this picks the "best available" GIC version
whether you're using KVM or TCG, so it behaves like 'host' when
using KVM, and gives you GICv3 when using TCG.
Also like '-cpu host', using -machine gic-version=max' means there
is no guarantee of migration compatibility between QEMU versions;
in future 'max' might mean '4'.

Now we have a working '-cpu max', the linux-user-only
'any' CPU is pretty much the same thing, so implement it
that way.
For the moment we don't add any of the extra feature bits
to the system-emulation "max", because we don't set the
ID register bits we would need to to advertise those
features as present.

Add support for "-cpu max" for ARM guests. This CPU type behaves
like "-cpu host" when KVM is enabled, and like a system CPU with
the maximum possible feature set otherwise. (Note that this means
it won't be migratable across versions, as we will likely add
features to it in future.)

Move the definition of the 'host' cpu type into cpu.c, where all the
other CPU types are defined. We can do this now we've decoupled it
from the KVM-specific host feature probing. This means we now create
the type unconditionally (assuming we were built with KVM support at
all), but if you try to use it without -enable-kvm this will end
up in the "host cpu probe failed and KVM not enabled" path in
arm_cpu_realizefn(), for an appropriate error message.
