005feccf62 memory-device: trace when pre_plugging/plugging/unplugging
Let's trace the address and the id of a memory device when
pre_plugging/plugging/unplugging succeeded.

Trace it when pre_plugging as well as when plugging, so we really know
when a specific address is actually used.

c331d3e136 memory-device: add device class function set_addr()
To be able to factor out address assignment of memory devices, we will
have to read (get_addr()) and write (set_addr()) the address.

We can't use properties for this purpose, as properties are device
specific. E.g. while the address property for a DIMM is called "addr", it
might be called differently (e.g. "memaddr") for other devices.

Especially virtio based memory devices cannot use "addr" as that is already
reserved and used for the address on the bus (for the proxy device).

Also, it might be possible to have memory devices without address
properties (e.g. internal DIMM-like thingies).

In contrast to get_addr(), we expect that set_addr() can fail.

Keep it simple for now for pc-dimm and simply set the static property, that
will fail once realized.

af39002747 memory-device: drop get_region_size()
There are no remaining users of get_region_size() except
memory_device_get_region_size() itself. We can make
memory_device_get_region_size() work directly on get_memory_region()
instead and drop get_region_size().

In addition, we can now use memory_device_get_region_size() in pc-dimm
code to implement get_plugged_size()"

3a0a2b0a2b memory-device: factor out get_memory_region() from pc-dimm
The memory region is necessary for plugging/unplugging a memory device.
The region size (via get_region_size()) is no longer sufficient, as
besides the alignment, also the region itself is required in order to
add it to the device memory region of the machine via
- memory_region_add_subregion
- memory_region_del_subregion

So, to factor out plugging/unplugging of memory devices from pc-dimm
code, we have to factor out access to the memory region first.

946d6154ab memory-device: add and use memory_device_get_region_size()
We will factor out get_memory_region() from pc-dimm to memory device code
soon. Once that is done, get_region_size() can be implemented
generically and essentially be replaced by
memory_device_get_region_size (and work only on get_memory_region()).

We have some users of get_memory_region() (spapr and pc-dimm code) that are
only interested in the size. So let's rework them to use
memory_device_get_region_size() first, then we can factor out
get_memory_region() and eventually remove get_region_size() without
touching the same code multiple times.

e40c5b6b3f memory-device: forward errors in get_region_size()/get_plugged_size()
Let's properly forward the errors, so errors from get_region_size() /
get_plugged_size() can be handled.

Users right now call both functions after the device has been realized,
which is will never fail, so it is fine to continue using error_abort.

While at it, remove a leftover error check (suggested by Igor).

b836723dfe fsdev: Clean up error reporting in qemu_fsdev_add()
Calling error_report() from within a function that takes an Error **
argument is suspicious.  qemu_fsdev_add() does that, and its caller
fsdev_init_func() then fails without setting an error.  Its caller
main(), via qemu_opts_foreach(), is fine with it, but clean it up
anyway.

fff4c9c325 xen/pt: Fix incomplete conversion to realize()
The conversion of "xen-pci-passthrough" to realize() (commit
5a11d0f754, v2.6.0) neglected to convert the xen_pt_config_init()
error path.  If xen_pt_config_init() fails, xen_pt_realize() reports
the error, then returns success without completing its job.  I don't
know the exact impact, but it can't be good.

Belatedly convert the error path.

Calling error_report() in a function that takes an Error ** argument

also passes &error_fatal to qemu_opts_validate().  Both wrong, but
currently harmless, as its only caller passes &error_fatal.  Messed up
in commit 1007a37e20.  Clean it up.

d319e05d6f pc: Fix machine property nvdimm-persistence error handling
Calling error_report() in a function that takes an Error ** argument
is suspicious.  pc.c's pc_machine_set_nvdimm_persistence() does that,
and then exit()s.  Wrong.  Attempting to set machine property
nvdimm-persistence to a bad value instantly kills the VM:

    $ qemu-system-x86_64 -nodefaults -S -display none -qmp stdio
    {"QMP": {"version": {"qemu": {"micro": 50, "minor": 0, "major": 3}, "package": "v3.0.0-837-gc5e4e49258"}, "capabilities": []}}
    {"execute": "qmp_capabilities"}
    {"return": {}}
    {"execute": "qom-set", "arguments": {"path": "/machine", "property": "nvdimm-persistence", "value": "instadeath"}}
    -machine nvdimm-persistence=instadeath: unsupported option
    $ echo $?
    1

Broken when commit 11c39b5cd9 (v3.0.0) replaced error_propagate();
return by error_report(); exit() instead of error_setg(); return.  Fix
that.

1245402e3c 9pfs: Fix CLI parsing crash on error
Calling error_report() in a function that takes an Error ** argument
is suspicious.  9p-handle.c's handle_parse_opts() does that, and then
fails without setting an error.  Wrong.  Its caller crashes when it
tries to report the error:

    $ qemu-system-x86_64 -nodefaults -fsdev id=foo,fsdriver=handle
    qemu-system-x86_64: -fsdev id=foo,fsdriver=handle: warning: handle backend is deprecated
    qemu-system-x86_64: -fsdev id=foo,fsdriver=handle: fsdev: No path specified
    Segmentation fault (core dumped)

Screwed up when commit 91cda4e8f3 (v2.12.0) converted the function to
Error.  Fix by calling error_setg() instead of error_report().

c3b8e3e0ed vfio: Clean up error reporting after previous commit
The previous commit changed vfio's warning messages from

    vfio warning: DEV-NAME: Could not frobnicate

to

    warning: vfio DEV-NAME: Could not frobnicate

To match this change, change error messages from

    vfio error: DEV-NAME: On fire

to

    vfio DEV-NAME: On fire

Note the loss of "error".  If we think marking error messages that way
is a good idea, we should mark *all* error messages, i.e. make
error_report() print it.

e1eb292ace vfio: Use warn_report() & friends to report warnings
The vfio code reports warnings like

    error_report(WARN_PREFIX "Could not frobnicate", DEV-NAME);

where WARN_PREFIX is defined so the message comes out as

    vfio warning: DEV-NAME: Could not frobnicate

This usage predates the introduction of warn_report() & friends in
commit 97f40301f1.  It's time to convert to that interface.  Since
these functions already prefix the message with "warning: ", replace
WARN_PREFIX by VFIO_MSG_PREFIX, so the messages come out like

    warning: vfio DEV-NAME: Could not frobnicate

The next commit will replace ERR_PREFIX.

While there, split a warning consisting of multiple sentences to
