Move vfio_spapr_container_setup() to a VFIOIOMMUClass::setup handler
and convert the sPAPR VFIOIOMMUOps struct to a QOM interface. The
sPAPR QOM interface inherits from the legacy QOM interface because
because both have the same basic needs. The sPAPR interface is then
extended with the handlers specific to the sPAPR IOMMU.
This allows reuse and provides better abstraction of the backends. It
will be useful to avoid compiling the sPAPR IOMMU backend on targets
not supporting it.

VFIOContainerBase was not introduced as an abstract QOM object because
it felt unnecessary to expose all the IOMMU backends to the QEMU
machine and human interface. However, we can still abstract the IOMMU
backend handlers using a QOM interface class. This provides more
flexibility when referencing the various implementations.
Simply transform the VFIOIOMMUOps struct in an InterfaceClass and do
some initial name replacements. Next changes will start converting
VFIOIOMMUOps.

The edu_check_range function checks that start <= end1 < end2, where
end1 is the upper bound (exclusive) of the guest-supplied DMA range and
end2 is the upper bound (exclusive) of the device's allowed DMA range.
When the guest tries to transfer exactly DMA_SIZE (4096) bytes, end1
will be equal to end2, so the check fails and QEMU aborts with this
puzzling error message (newlines added for formatting):
qemu: hardware error: EDU: DMA range
0x0000000000040000-0x0000000000040fff out of bounds
(0x0000000000040000-0x0000000000040fff)!
By checking end1 <= end2 instead, guests will be allowed to transfer
exactly 4096 bytes. It is not necessary to explicitly check for
start <= end1 because the previous two checks (within(addr, start, end2)
and end1 > addr) imply start < end1.

It's no sense to check the CPU type when mc->valid_cpu_types[0] is

A precise hint for the error message is given when mc->valid_cpu_types[0]
is the only valid entry. Besides, enumeration on mc->valid_cpu_types[0]
when we have mutiple valid entries there is avoided to increase the code
readability, as suggested by Philippe Mathieu-Daudé.
Besides, @cc comes from machine->cpu_type or mc->default_cpu_type. For

Functions that use an Error **errp parameter to return errors should
not also report them to the user, because reporting is the caller's
job. The principle is violated by machine_run_board_init() because
it calls error_report(), error_printf(), and exit(1) when the machine
doesn't support the requested CPU type.
Clean this up by using error_setg() and error_append_hint() instead.

When a vm transitions from running to suspended, runstate notifiers are
not called, so the notifiers still think the vm is running. Hence, when
we call vm_start to restore the suspended state, we call vm_state_notify
with running=1. However, some notifiers check for RUN_STATE_RUNNING.
They must check the running boolean instead.
No functional change.

This variable is about the host OS, not the target. It is used a lot
more since the Meson conversion, but the original sin dates back to 2003.

config_all now lists only accelerators, rename it to indicate its actual

CONFIG_ALL is tricky to use and was ported over to Meson from the
recursive processing of Makefile variables. Meson sourcesets
however have all_sources() and all_dependencies() methods that
remove the need for it.

The sgx_epc_get_section stub is reachable from cpu_x86_cpuid. It
should not assert, instead it should just return true just like
the "real" sgx_epc_get_section does when SGX is disabled.
