Removes a whole lot of unnecessary boilerplate code. Machines
don't need to be objects. The expansion of the SOC object model
for the RISC-V machines will happen in the future as SiFive
plans to add their FE310 and FU540 SOCs to QEMU. However, it
seems that this present boilerplate is complete unnecessary.

We set up the infrastructure to enumerate all the PCI devices
attached to the SMMU and create an associated IOMMU memory
region and address space.
Those info are stored in SMMUDevice objects. The devices are
grouped according to the PCIBus they belong to. A hash table
indexed by the PCIBus pointer is used. Also an array indexed by
the bus number allows to find the list of SMMUDevices.

When running omap1/2 or pxa2xx based ARM machines with -nodefaults,
they bail out immediately complaining about a "missing SecureDigital
device". That's not how the "default" devices in vl.c are meant to
work - it should be possible for a board to also start up without
default devices. So let's turn the error message and exit() into
a warning instead.

This allows to pin the host controller in the Linux PCI domain space.
Linux requires that property to be available consistently or not at all,
in which case the domain number becomes unstable on additions/removals.
Adding it here won't make a difference in practice for most setups as we
only expose one controller.
However, enabling Jailhouse on top may introduce another controller, and
that one would like to have stable address as well. So the property is
needed for the first controller as well.

The NBD spec is proposing a relaxation of NBD_CMD_BLOCK_STATUS
where a server may have the final extent per context give a
length beyond the original request, if it can easily prove that
subsequent bytes have the same status, on the grounds that a
client can take advantage of this information for fewer block
status requests. Since qemu 2.12 as a client always sends
NBD_CMD_FLAG_REQ_ONE, and rejects a server that sends extra
length, the upstream NBD spec will probably limit this behavior
to clients that don't request REQ_ONE semantics; but it doesn't
hurt to relax qemu to always be permissive of this server
behavior, even if it continues to use REQ_ONE.

Initialize received variable. Otherwise, is is possible for server to
answer without any contexts, but we will set context_id to something
random (received_id is not initialized too) and return 1, which is
wrong.
To solve it, just initialize received to false. Initialize received_id
too, just to make all possible checkers happy.

The TARGET_BASE_ARCH values from "configure" don't all map to the
@CpuInfoArch enum constants; in particular "s390x" from the former does
not match @s390 in the latter. Clients are known to rely on the @s390
constant specifically, so we can't change it silently. Instead, deprecate
the @CpuInfoFast.@arch member (in favor of @CpuInfoFast.@target) using the
regular deprecation process.
(No deprecation reminder is added to sysemu_target_to_cpuinfo_arch(): once
@CpuInfoFast.@arch is removed, the assignment expression that calls
sysemu_target_to_cpuinfo_arch() from qmp_query_cpus_fast() will have to
disappear; in turn the static function left without callers will also
break the build, thus it'll have to go.)

Add a new field @target (of type @SysEmuTarget) to the output of the
@query-cpus-fast command, which provides more information about the
emulation target than the field @arch (of type @CpuInfoArch). Make @target
the new discriminator for the @CpuInfoFast return structure. Keep @arch
for compatibility.

We'll soon need an enumeration type that lists all the softmmu targets
that QEMU (the project) supports. Introduce @SysEmuTarget to
"common.json".
The enum constant @x86_64 doesn't match the QAPI convention of preferring
hyphen ("-") over underscore ("_"). This is intentional; the @SysEmuTarget
constants are supposed to produce QEMU executable names when stringified
and appended to the "qemu-system-" prefix. Put differently, the
replacement text of the TARGET_NAME preprocessor macro must be possible to
look up in the list of (stringified) enum constants.
Like other enum types, @SysEmuTarget too can be used for discriminator
fields in unions. For the @i386 constant, a C-language union member called
"i386" would be generated. On mingw build hosts, "i386" is a macro
however. Add "i386" to "polluted_words" at once.

* Commit ca230ff33f added the @arch field to @CpuInfoFast, but it failed
to set the new field in qmp_query_cpus_fast(), when TARGET_S390X was not
defined. The updated @query-cpus-fast example in "qapi-schema.json"
showed "arch":"x86" only because qmp_query_cpus_fast() calls g_malloc0()
to allocate @CpuInfoFast, and the CPU_INFO_ARCH_X86 enum constant is
generated with value 0.
All @arch values other than @s390 implied the @CpuInfoOther sub-struct
for @CpuInfoFast -- at the time of writing the patch --, thus no fields
other than @arch needed to be set when TARGET_S390X was not defined. Set
@arch now, by copying the corresponding assignments from
qmp_query_cpus().
* Commit 25fa194b7b added the @riscv enum constant to @CpuInfoArch (used
in both @CpuInfo and @CpuInfoFast -- the return types of the @query-cpus
and @query-cpus-fast commands, respectively), and assigned, in both
return structures, the @CpuInfoRISCV sub-structure to the new enum
value.
However, qmp_query_cpus_fast() would not populate either the @arch field
or the @CpuInfoRISCV sub-structure, when TARGET_RISCV was defined; only
qmp_query_cpus() would.
Assign @CpuInfoOther to the @riscv enum constant in @CpuInfoFast, and
populate only the @arch field in qmp_query_cpus_fast(). Getting CPU
state without interrupting KVM is an exceptional thing that only S390X
does currently. Quoting Cornelia Huck <cohuck@redhat.com>, "s390x is
exceptional in that it has state in QEMU that is actually interesting
for upper layers and can be retrieved without performance penalty". See
