edcbea008d hw/display/edid: Add missing 'qdev-properties.h' header
When trying to consume the DEFINE_EDID_PROPERTIES() macro
by including "hw/display/edid.h", we get this build failure:

  include/hw/display/edid.h:24:5: error: implicit declaration of
  function ‘DEFINE_PROP_UINT32’ [-Werror=implicit-function-declaration]
     24 |     DEFINE_PROP_UINT32("xres", _state, _edid_info.prefx, 0),    \
        |     ^~~~~~~~~~~~~~~~~~

Headers should be self-contained, and one shouldn't have to
dig to find the missing headers.
In this case "hw/qdev-properties.h" is missing. Add it.

0911a60c76 ppc/spapr: Add hotremovable flag on DIMM LMBs on drmem_v2
On reboot, all memory that was previously added using object_add and
device_add is placed in this DIMM area.

The new SPAPR_LMB_FLAGS_HOTREMOVABLE flag helps Linux to put this memory in
the correct memory zone, so no unmovable allocations are made there,
allowing the object to be easily hot-removed by device_del and
object_del.

This new flag was accepted in Power Architecture documentation.

c6996cf9a6 blockdev: Promote several bitmap functions to non-static
The next patch will split blockdev.c, which will require accessing
some previously-static functions from more than one .c file.  But part
of promoting a function to public is picking a naming scheme that does
not reek of exposing too many internals (two of the three functions
were named starting with 'do_').  To make future code motion easier,
perform the function rename and non-static promotion into its own
patch.

ef893b5c84 block: Make it easier to learn which BDS support bitmaps
Upcoming patches will enhance bitmap support in qemu-img, but in doing
so, it turns out to be nice to suppress output when persistent bitmaps
make no sense (such as on a qcow2 v2 image).  Add a hook to make this
easier to query.

This patch adds a new callback .bdrv_supports_persistent_dirty_bitmap,
rather than trying to shoehorn the answer in via existing callbacks.
In particular, while it might have been possible to overload
.bdrv_co_can_store_new_dirty_bitmap to special-case a NULL input to
answer whether any persistent bitmaps are supported, that is at odds
with whether a particular bitmap can be stored (for example, even on
an image that supports persistent bitmaps but has currently filled up
the maximum number of bitmaps, attempts to store another one should
fail); and the new functionality doesn't require coroutine safety.
Similarly, we could have added one more piece of information to
.bdrv_get_info, but then again, most callers to that function tend to
already discard extraneous information, and making it a catch-all
rather than a series of dedicated scalar queries hasn't really
simplified life.

In the future, when we improve the ability to look up bitmaps through
a filter, we will probably also want to teach the block layer to
automatically let filters pass this request on through.

2df9f5718d ui/win32-kbd-hook: handle AltGr in a hook procedure
Import win32 keyboard hooking code from project spice-gtk. This
patch removes the extra left control key up/down input events
inserted by Windows for the right alt key up/down input events
with international keyboard layouts. Additionally there's some
code to grab the keyboard.

The next patches will use this code.

Only Windows needs this.

ba607ca8bf aio-posix: disable fdmon-io_uring when GSource is used
The glib event loop does not call fdmon_io_uring_wait() so fd handlers
waiting to be submitted build up in the list. There is no benefit is
using io_uring when the glib GSource is being used, so disable it
instead of implementing a more complex fix.

This fixes a memory leak where AioHandlers would build up and increasing
amounts of CPU time were spent iterating them in aio_pending(). The
symptom is that guests become slow when QEMU is built with io_uring
support.

Any current user of child_file, child_format, and child_backing can and

appropriate BdrvChildRole when the child is created/attached.  (The
following commits will take care of that.)

3cdc69d31b block: Pass parent_is_format to .inherit_options()
We plan to unify the generic .inherit_options() functions.  The
resulting common function will need to decide whether to force-enable
format probing, force-disable it, or leave it as-is.  To make this
decision, it will need to know whether the parent node is a format node
or not (because we never want format probing if the parent is a format
node already (except for the backing chain)).

bd86fb990c block: Rename BdrvChildRole to BdrvChildClass
This structure nearly only contains parent callbacks for child state
changes.  It cannot really reflect a child's role, because different

because parents can have custom callbacks even when the child fulfills a
standard role.

d67066d8bc block: Add BlockDriver.is_format
We want to unify child_format and child_file at some point.  One of the
important things that set format drivers apart from other drivers is
that they do not expect other format nodes under them (except in the
backing chain), i.e. we must not probe formats inside of formats.  That
means we need something on which to distinguish format drivers from
others, and hence this flag.

(WRITE_UNCHANGED suffices, because callers generally use this function
to clear a node with a backing file after a commit operation.)

Introduce bdrv_make_empty() that verifies that it does.

This reverts commit f79081b4b7.

Patch has broken byteorder handling: RAMFBCfg fields are in bigendian
byteorder, the reset function doesn't care so native byteorder is used
instead.  Given this went unnoticed so far the feature is obviously
unused, so just revert the patch.
