Thomas Huth bc3d41a9f6 migration/ram: Fix compilation with -Wshadow=local
Rename the variable here to avoid that it shadows a variable from
the beginning of the function scope. With this change the code now
successfully compiles with -Wshadow=local.

This function is only used for compression.  So we rename it as
compress_send_queued_data().  We put it on ram-compress.h because we
are moving it later to ram-compress.c.

libfdt is installed in /usr/local on FreeBSD, and since this
library does not have a pkg-config file, we have to specify the
paths manually. This way we can avoid that Meson has to recompile

Thomas Huth c7437f0ddb docs/about: Mark the old pc-i440fx-2.0 - 2.3 machine types as deprecated
As we've seen in the past, it's useful for deprecating old machine
types to finally be able to get of legacy code or do other clean-ups
(see e.g. commit ea985d235b that was used to drop the PCI code in
the 128k bios binaries to free some precious space in those binaries).

So let's continue deprecating the oldest pc machine types. QEMU 2.3
has been released 8 years ago, so that's plenty of time since such
machine types have been used by default, thus deprecating pc-i440fx-2.0
up to pc-i440fx-2.3 should be fine nowadays.

Paolo Bonzini 2cb81af0b1 kvm: unify listeners for PIO address space
Since we now assume that ioeventfds are present, kvm_io_listener is always
registered.  Merge it with kvm_coalesced_pio_listener in a single
listener.  Since PIO space does not have KVM memslots attached to it,
the priority is irrelevant.

Paolo Bonzini 5d9ec1f4c7 kvm: assume that many ioeventfds can be created
NR_IOBUS_DEVS was increased to 200 in Linux 2.6.34.  By Linux 3.5 it had
increased to 1000 and later ioeventfds were changed to not count against
the limit.  But the earlier limit of 200 would already be enough for
kvm_check_many_ioeventfds() to be true, so remove the check.

Paolo Bonzini cc5e719e2c kvm: require KVM_CAP_SIGNAL_MSI
This was introduced in KVM in Linux 3.5, we can require it unconditionally
in kvm_irqchip_send_msi().  However, not all architectures have to implement
it so check it only in x86, the only architecture that ever had MSI injection
but not KVM_CAP_SIGNAL_MSI.

ARM uses it to detect the presence of the ITS emulation in the kernel,
introduced in Linux 4.8.  Assume that it's there and possibly fail when
realizing the arm-its-kvm device.
