Initial conversion of HMP debugging commands to QMP
This introduces a new policy that all HMP commands will be converted to
have QMP equivalents, marked unstable if no formal QAPI modelling is
intended to be done.
New unstable commands are added as follows:
- HMP "info roms" => QMP "x-query-roms"
- HMP "info profile" => QMP "x-query-profile"
- HMP "info numa" => QMP "x-query-numa"
- HMP "info usb" => QMP "x-query-usb"
- HMP "info rdma" => QMP "x-query-rdma"
- HMP "info ramblock" => QMP "x-query-ramblock"
- HMP "info irq" => QMP "x-query-irq"
- HMP "info jit" => QMP "x-query-jit"
- HMP "info opcount" => QMP "x-query-opcount"

usb-storage: tag usb_msd_csw as packed struct
Without this the struct has the wrong size: sizeof() evaluates
to 16 instead of 13. In most cases the bug is hidden by the
fact that guests submits a buffer which is exactly 13 bytes
long, so the padding added by the compiler is simply ignored.
But sometimes guests submit a larger buffer and expect a short
transfer, which does not work properly with the wrong struct
size.

ui/gtk: Update the refresh rate for gl-area too
This is a bugfix that stretches all the way back to January 2020,
where I initially introduced this problem and potential solutions.
A quick recap of the issue: QEMU did not sync up with the monitors
refresh rate causing the VM to render frames that were NOT displayed
to the user. That "fix" allowed QEMU to obtain the screen refreshrate
information from the system using GDK API's and was for GTK only.
Well, I'm back with the same issue again. But this time on Wayland.
And I did NOT realize there was YET another screen refresh rate
function, this time for Wayland specifically. Thankfully the fix was
simple and without much hassle.
Thanks,
Nikola

docs/devel: document expectations for HMP commands in the future
We no longer wish to have commands implemented in HMP only. All commands
should start with a QMP implementation and the HMP merely be a shim
around this. To reduce the burden of implementing QMP commands where
there is low expectation of machine usage, requirements for QAPI
modelling are relaxed provided the command is under the "x-" name
prefix.

docs/devel: document expectations for QAPI data modelling for QMP
Traditionally we have required that newly added QMP commands will model
any returned data using fine grained QAPI types. This is good for
commands that are intended to be consumed by machines, where clear data
representation is very important. Commands that don't satisfy this have
generally been added to HMP only.
In effect the decision of whether to add a new command to QMP vs HMP has
been used as a proxy for the decision of whether the cost of designing a
fine grained QAPI type is justified by the potential benefits.
As a result the commands present in QMP and HMP are non-overlapping
sets, although HMP comamnds can be accessed indirectly via the QMP
command 'human-monitor-command'.
One of the downsides of 'human-monitor-command' is that the QEMU monitor
APIs remain tied into various internal parts of the QEMU code. For
example any exclusively HMP command will need to use 'monitor_printf'
to get data out. It would be desirable to be able to fully isolate the
monitor implementation from QEMU internals, however, this is only
possible if all commands are exclusively based on QAPI with direct
QMP exposure.
The way to achieve this desired end goal is to finese the requirements
for QMP command design. For cases where the output of a command is only
intended for human consumption, it is reasonable to want to simplify
the implementation by returning a plain string containing formatted
data instead of designing a fine grained QAPI data type. This can be
permitted if-and-only-if the command is exposed under the 'x-' name
prefix. This indicates that the command data format is liable to
future change and that it is not following QAPI design best practice.
The poster child example for this would be the 'info registers' HMP
command which returns printf formatted data representing CPU state.
This information varies enourmously across target architectures and
changes relatively frequently as new CPU features are implemented.
It is there as debugging data for human operators, and any machine
usage would treat it as an opaque blob. It is thus reasonable to
expose this in QMP as 'x-query-registers' returning a 'str' field.

monitor: introduce HumanReadableText and HMP support
This provides a foundation on which to convert simple HMP commands to
use QMP. The QMP implementation will generate formatted text targeted
for human consumption, returning it in the HumanReadableText data type.
The HMP command handler will simply print out the formatted string
within the HumanReadableText data type. Since this will be an entirely
formulaic action in the case of HMP commands taking no arguments, a
custom command handler is provided.
Thus instead of registering a 'cmd' callback for the HMP command, a
'cmd_info_hrt' callback is provided, which will simply be a pointer
to the QMP implementation.

Revert "elf: Relax MIPS' elf_check_arch() to accept EM_NANOMIPS too"
Per the "P32 Porting Guide" (rev 1.2) [1], chapter 2:
p32 ABI Overview
----------------
The Application Binary Interface, or ABI, is the set of rules
that all binaries must follow in order to run on a nanoMIPS
system. This includes, for example, object file format,
instruction set, data layout, subroutine calling convention,
and system call numbers. The ABI is one part of the mechanism
that maintains binary compatibility across all nanoMIPS platforms.
p32 improves on o32 to provide an ABI that is efficient in both
code density and performance. p32 is required for the nanoMIPS
architecture.
So far QEMU only support the MIPS o32 / n32 / n64 ABIs. The p32 ABI
is not implemented, therefore we can not run any nanoMIPS binary.

Note, the format definition could be named @3rf_b (for
3R with a df field BYTE-based) but since the instruction
class is named '3R', we simply call the format @3r to
ease reviewing the msa.decode file.
However we directly call the trans_msa_3rf() function,
which handles the BYTE-based df field.

The LBA28 capacity (at offsets 60/61 of identification) is supposed to
express the maximum size supported by LBA28 commands. If the device is
larger than this, we have to cap it to 2^28-1.
At least NetBSD happens to be using this value to determine whether to use

block/rbd: implement bdrv_co_block_status
the qemu rbd driver currently lacks support for bdrv_co_block_status.
This results mainly in incorrect progress during block operations (e.g.
qemu-img convert with an rbd image as source).
This patch utilizes the rbd_diff_iterate2 call from librbd to detect
allocated and unallocated (all zero areas).
To avoid querying the ceph OSDs for the answer this is only done if
the image has the fast-diff feature which depends on the object-map and
exclusive-lock features. In this case it is guaranteed that the information
is present in memory in the librbd client and thus very fast.
If fast-diff is not available all areas are reported to be allocated
which is the current behaviour if bdrv_co_block_status is not implemented.

block/vpc: Add a sanity check that fixed-size images have the right type
The code in vpc.c uses BDRVVPCState->footer.type in various places
to decide whether the image is a fixed-size (VHD_FIXED) or a dynamic
(VHD_DYNAMIC) image. However, we never check that this field really
contains VHD_FIXED if we detected a fixed size image in vpc_open(),
so a wrong value here could cause quite some trouble during runtime.

vmdk: allow specification of tools version
VMDK files support an attribute that represents the version of the guest
tools that are installed on the disk.
This attribute is used by vSphere before a machine has been started to
determine if the VM has the guest tools installed.
This is important when configuring "Operating system customizations" in
vSphere, as it checks for the presence of the guest tools before
allowing those customizations.
Thus when the VM has not yet booted normally it would be impossible to
customize it, therefore preventing a customized first-boot.
The attribute should not hurt on disks that do not have the guest tools
installed and indeed the VMware tools also unconditionally add this
attribute.
(Defaulting to the value "
2147483647", as is done in this patch)
