target/riscv: Simplify probing in vext_ldff

The current pairing of tlb_vaddr_to_host with extra is either

Mark the reserve_addr check unlikely.  Use tlb_vaddr_to_host

for page writability.  Use set/clear_helper_retaddr so that

With this, a trivial loop around guest memset will no longer

chardev/char-win-stdio.c: restore old console mode

If I use `-serial stdio` on Windows, after QEMU exits, the terminal
could not handle arrow keys and tab any more. Because stdio backend
on Windows sets console mode to virtual terminal input when starts,
but does not restore the old mode when finalize.

This small patch saves the old console mode and set it back.

target/s390x: filter deprecated properties based on model expansion type

Currently, there is no way to execute the query-cpu-model-expansion
command to retrieve a comprehenisve list of deprecated properties, as
the result is dependent per-model. To enable this, the expansion output
is modified as such:

When reporting a "full" CPU model, show the *entire* list of deprecated
properties regardless if they are supported on the model. A full
expansion outputs all known CPU model properties anyway, so it makes
sense to report all deprecated properties here too.

This allows management apps to query a single model (e.g. host) to
acquire the full list of deprecated properties.

Additionally, when reporting a "static" CPU model, the command will
only show deprecated properties that are a subset of the model's
*enabled* properties. This is more accurate than how the query was
handled before, which blindly reported deprecated properties that
were never otherwise introduced for certain models.

hw: Fix crash that happens when introspecting scsi-block on older machine types

"make check SPEED=slow" is currently failing the device-introspect-test on
older machine types since introspecting "scsi-block" is causing an abort:

 $ ./qemu-system-x86_64 -M pc-q35-8.0 -monitor stdio
 QEMU 9.0.50 monitor - type 'help' for more information
 (qemu) device_add scsi-block,help

 can't apply global scsi-disk-base.migrate-emulated-scsi-request=false:
 Property 'scsi-block.migrate-emulated-scsi-request' not found
 Aborted (core dumped)

The problem is that the compat code tries to change the
"migrate-emulated-scsi-request" property for all devices that are
derived from "scsi-block", but the property has only been added
to "scsi-hd" and "scsi-cd" via the DEFINE_SCSI_DISK_PROPERTIES macro.

Thus let's fix the problem by only changing the property on the devices
that really have this property.

Cursor: 8 -> 1 bit alpha downsampling improvement

Mouse cursors with 8 bit alpha were downsampled to 1-bit opacity maps by
turning alpha values of 255 into 1 and everything else into 0. This
means that mostly-opaque pixels ended up completely invisible.

This patch changes the behaviour so that only pixels with less than 50%
alpha (0-127) are treated as transparent when converted to 1-bit alpha.

This greatly improves the subjective appearance of anti-aliased mouse
cursors, such as those used by macOS, when using a front-end UI without
support for alpha-blended cursors, such as some VNC clients.

plugins/stoptrigger: TCG plugin to stop execution under conditions

This new plugin allows to stop emulation using conditions on the
emulation state. By setting this plugin arguments, it is possible
to set an instruction count limit and/or trigger address(es) to stop at.
The code returned at emulation exit can be customized.

This plugin demonstrates how someone could stop QEMU execution.
It could be used for research purposes to launch some code and
deterministically stop it and understand where its execution flow went.

gdbstub: Re-factor gdb command extensions

Coverity reported a memory leak (CID 1549757) in this code and its
admittedly rather clumsy handling of extending the command table.
Instead of handing over a full array of the commands lets use the
lighter weight GPtrArray and simply test for the presence of each
entry as we go. This avoids complications of transferring ownership of

qga: centralize logic for disabling/enabling commands

It is confusing having many different pieces of code enabling and
disabling commands, and it is not clear that they all have the same
semantics, especially wrt prioritization of the block/allow lists.
The code attempted to prevent the user from setting both the block
and allow lists concurrently, however, the logic was flawed as it
checked settings in the configuration file  separately from the
command line arguments. Thus it was possible to set a block list
in the config file and an allow list via a command line argument.
The --dump-conf option also creates a configuration file with both
keys present, even if unset, which means it is creating a config
that cannot actually be loaded again.

Centralizing the code in a single method "ga_apply_command_filters"
will provide a strong guarantee of consistency and clarify the
intended behaviour. With this there is no compelling technical
reason to prevent concurrent setting of both the allow and block
lists, so this flawed restriction is removed.

qga: allow configuration file path via the cli

the default configuration file path is very unusual practice, made

This introduces the more normal '-c PATH'  / '--config=PATH' command

qga: don't disable fsfreeze commands if vss_init fails

The fsfreeze commands are already written to report an error if
vss_init() fails. Reporting a more specific error message is more
helpful than a generic "command is disabled" message, which cannot
between an admin config decision and lack of platform support.

qga: conditionalize schema for commands not supported on other UNIX

Rather than creating stubs for every command that just return

This changes the error message for affected commands from
