machine: Replace has_dynamic_sysbus with list of allowed devices
The existing has_dynamic_sysbus flag makes the machine accept
every user-creatable sysbus device type on the command-line.
Replace it with a list of allowed device types, so machines can
easily accept some sysbus devices while rejecting others.
To keep exactly the same behavior as before, the existing
has_dynamic_sysbus=true assignments are replaced with a
TYPE_SYS_BUS_DEVICE entry on the allowed list. Other patches
will replace the TYPE_SYS_BUS_DEVICE entries with more specific
lists of devices.

qdev: Check for the availability of a hotplug controller before adding a
device
The qdev_unplug() function contains a g_assert(hotplug_ctrl) statement,
so QEMU crashes when the user tries to device_add + device_del a device
that does not have a corresponding hotplug controller. This could be
provoked for a couple of devices in the past (see commit 4c93950659487c7ad
or 84ebd3e8c7d4fe955 for example), and can currently for example also be
triggered like this:
$ s390x-softmmu/qemu-system-s390x -M none -nographic
QEMU 2.10.50 monitor - type 'help' for more information
(qemu) device_add qemu-s390x-cpu,id=x
(qemu) device_del x
**
ERROR:qemu/qdev-monitor.c:872:qdev_unplug: assertion failed: (hotplug_ctrl)
Aborted (core dumped)
So devices clearly need a hotplug controller when they should be usable
with device_add.
The code in qdev_device_add() already checks whether the bus has a proper
hotplug controller, but for devices that do not have a corresponding bus,
there is no appropriate check available yet. In that case we should check
whether the machine itself provides a suitable hotplug controller and
refuse to plug the device if none is available.

Log Message:

hostmem-file: add "align" option
When mmap(2) the backend files, QEMU uses the host page size
(getpagesize(2)) by default as the alignment of mapping address.
However, some backends may require alignments different than the page
size. For example, mmap a device DAX (e.g., /dev/dax0.0) on Linux
kernel 4.13 to an address, which is 4K-aligned but not 2M-aligned,
fails with a kernel message like
[617494.969768] dax dax0.0: qemu-system-x86: dax_mmap: fail, unaligned vma
(0x7fa37c579000 - 0x7fa43c579000, 0x1fffff)
Because there is no common approach to get such alignment requirement,
we add the 'align' option to 'memory-backend-file', so that users or
management utils, which have enough knowledge about the backend, can
specify a proper alignment via this option.

nvdimm: add 'unarmed' option
Currently the only vNVDIMM backend can guarantee the guest write
persistence is device DAX on Linux, because no host-side kernel cache
is involved in the guest access to it. The approach to detect whether
the backend is device DAX needs to access sysfs, which may not work
with SELinux.
Instead, we add the 'unarmed' option to device 'nvdimm', so that users
or management utils, which have enough knowledge about the backend,
can control the unarmed flag in guest ACPI NFIT via this option. The
guest Linux NVDIMM driver, for example, will mark the corresponding
vNVDIMM device read-only if the unarmed flag in guest NFIT is set.
The default value of 'unarmed' option is 'off' in order to keep the
backwards compatibility.

possible_cpus: add CPUArchId::type field
Remove dependency of possible_cpus on 1st CPU instance,
which decouples configuration data from CPU instances that

Also later it would be used for enabling early cpu to numa node
configuration at runtime qmp_query_hotpluggable_cpus() should
provide a list of available cpu slots at early stage,
before machine_init() is called and the 1st cpu is created,
so that mgmt might be able to call it and use output to set
numa mapping.
Use MachineClass::possible_cpu_arch_ids() callback to set
cpu type info, along with the rest of possible cpu properties,
to let machine define which cpu type* will be used.
* for SPAPR it will be a spapr core type and for ARM/s390x/x86
a respective descendant of CPUClass.
Move parse_numa_opts() in vl.c after cpu_model is parsed into
cpu_type so that possible_cpu_arch_ids() would know which
cpu_type to use during layout initialization.
