softmmu: fix device deletion events with -device JSON syntax

The -device JSON syntax impl leaks a reference on the created
DeviceState instance. As a result when you hot-unplug the
device, the device_finalize method won't be called and thus
it will fail to emit the required DEVICE_DELETED event.

A 'json-cli' feature was previously added against the
'device_add' QMP command QAPI schema to indicated to mgmt
apps that -device supported JSON syntax. Given the hotplug
bug that feature flag is not usable for its purpose, so
we add a new 'json-cli-hotplug' feature to indicate the
-device supports JSON without breaking hotplug.

It's also unfortunate that the ioctl will be disabled on Linux in case
the user did not install the right xfsprogs-devel package before running
configure. Thus let's simplify this by providing the ioctl definition

ppc/pnv: use stack->pci_regs[] in pnv_pec_stk_pci_xscom_write()

pnv_pec_stk_pci_xscom_write() is pnv_pec_stk_pci_xscom_ops write
callback. It writes values into regs in the stack->nest_regs[] array.
The pnv_pec_stk_pci_xscom_read read callback, on the other hand, returns
values of the stack->pci_regs[]. In fact, at this moment, the only use
of stack->pci_regs[] is in pnv_pec_stk_pci_xscom_read(). There's no code
that is written anything in stack->pci_regs[], which is suspicious.

Considering that stack->nest_regs[] is widely used by the nested
MemoryOps pnv_pec_stk_nest_xscom_ops, in both read and write callbacks,
the conclusion is that we're writing the wrong array in
pnv_pec_stk_pci_xscom_write(). This function should write stack->pci_regs[]
instead.

ppc/pnv: Introduce user creatable pnv-phb4 devices

This patch introduces pnv-phb4 user creatable devices that are created
in a similar manner as pnv-phb3 devices, allowing the user to interact
with the PHBs directly instead of creating PCI Express Controllers that
will create a certain amount of PHBs per controller index.

We accomplish this by doing the following:

- add a pnv_phb4_get_stack() helper to retrieve which stack an user
created phb4 would occupy;

- when dealing with an user created pnv-phb4 (detected by checking if
phb->stack is NULL at the start of phb4_realize()), retrieve its stack
and initialize its properties as done in stk_realize();

- use 'defaults_enabled()' in stk_realize() to avoid creating and
initializing a 'stack->phb' qdev that might be overwritten by an user
created pnv-phb4 device. This process is wrapped into a new helper
called pnv_pec_stk_default_phb_realize().

ppc/pnv: turn 'phb' into a pointer in struct PnvPhb4PecStack

At this moment, stack->phb is the plain PnvPHB4 device itself instead of
a pointer to the device. This will present a problem when adding user
creatable devices because we can't deal with this struct and the
realize() callback from the user creatable device.

We can't get rid of this attribute, similar to what we did when enabling
pnv-phb3 user creatable devices, because pnv_phb4_update_regions() needs
to access stack->phb to do its job. This function is called twice in
pnv_pec_stk_update_map(), which is one of the nested xscom write
callbacks (via pnv_pec_stk_nest_xscom_write()). In fact,
pnv_pec_stk_update_map() code comment is explicit about how the order of
the unmap/map operations relates with the PHB subregions.

All of this indicates that this code is tied together in a way that we
either go on a crusade, featuring lots of refactories and redesign and
considerable pain, to decouple stack and phb mapping, or we allow stack
update_map operations to access the associated PHB as it is today even
after introducing pnv-phb4 user devices.

This patch chooses the latter. Instead of getting rid of stack->phb,
turn it into a PHB pointer. This will allow us to assign an user created
PHB to an existing stack later. In this process,
pnv_pec_stk_instance_init() is removed because stack->phb is being
initialized in stk_realize() instead.

ppc/pnv: move PHB4 XSCOM init to phb4_realize()

and add_subregion() to phb4_realize() time is a natural thing to do
since it's strictly PHB related.

The remaining XSCOM initialization is also related to 'stack->phb' but
in a different manner. For instance, 'stack->nest_regs_mr'
MemoryRegionOps, 'pnv_pec_stk_nest_xscom_ops', uses
pnv_pec_stk_nest_xscom_write() as a write callback. When trying to write
the PEC_NEST_STK_BAR_EN reg, pnv_pec_stk_update_map() is called. Inside
this function, pnv_phb4_update_regions() is called twice. This function
uses 'stack->phb' to manipulate memory regions of the phb.

This is not a problem now but, when enabling user creatable phb4s, a
stack that doesn't have an associated phb (i.e. stack->phb = NULL) it
will cause a SIGINT during boot in pnv_phb4_update_regions().

All this can be avoided if all XSCOM realize is moved to phb4_realize(),
when we have certainty about the existence of 'stack->phb'. A lot of
code was moved from pnv_phb4_pec.c to pnv_phb4.c due to static constant
and variables being used but the cleaner logic is worth the trouble.

Most common QEMU buses and PCI controllers are named based on their bus

common name for a PCIE bus controller in QEMU is 'pcie'. Naming it
'pcie' would break the documented use of the pnv-phb3 device, since
'pcie.0' would now refer to the root bus instead of the first root port.

There's nothing particularly wrong with the 'root-bus' name used before,
aside from the fact that 'root-bus' is being used for pnv-phb3 and

the existing and the previously used name. Creating 3 phbs without ID

python/aqmp: use absolute import statement

pylint's dependency astroid appears to have bugs in 2.9.1 and 2.9.2 (Dec
31 and Jan 3) that appear to erroneously expect the qemu namespace to
have an __init__.py file. astroid 2.9.3 (Jan 9) avoids that problem, but
appears to not understand a relative import within a namespace package.

Update the relative import - it was worth changing anyway, because these
packages will eventually be packaged and distributed separately.
