Introducing additional required GSB elements and helper routines for state
exchange of each of the nested guest state elements for which get/set state

Since cap-nested-hv is an optional capability, it makes sense to register

requires to introduce a new API to unregister hypercalls to maintain
sanity across guest reboot since caps are re-applied across reboots and

The current post-loading code for scanout has a FIXME: it doesn't take
the resource region/rect into account. But there is more, when adding
blob migration support in commit f66767f75c, I didn't realize that blob
resources could be used for scanouts. This situationn leads to a crash
during post-load, as they don't have an associated res->image.
virtio_gpu_do_set_scanout() handle all cases, but requires the
associated virtio_gpu_framebuffer, which is currently not saved during
migration.
Add a v2 of "virtio-gpu-one-scanout" with the framebuffer fields, so we
can restore blob scanouts, as well as fixing the existing FIXME.

The error_vprepend() should use ERRP_GUARD() just as the documentation
of ERRP_GUARD() says:
> It must be used when the function dereferences @errp or passes
> @errp to error_prepend(), error_vprepend(), or error_append_hint().
Considering that error_vprepend() is also an API provided in error.h,
it is necessary to add it to the description of the rules for using
ERRP_GUARD().

NXP PCF8574 and compatible ICs are simple I2C GPIO expanders.
PCF8574 incorporates quasi-bidirectional IO, and simple
communication protocol, when IO read is I2C byte read, and
IO write is I2C byte write. User can think of it as
open-drain port, when line high state is input and line low
state is output.

This new parameter controls where the zero page checking is running.
1. If this parameter is set to 'legacy', zero page checking is
done in the migration main thread.
2. If this parameter is set to 'none', zero page checking is disabled.

A small number of migration options are accessed by migration clients,
but to see them clients must include all of options.h, which is mostly
for migration core code. migrate_mode() in particular will be needed by
multiple clients.
Refactor the option declarations so clients can see the necessary few via
misc.h, which already exports a portion of the client API.

Introduce a new enum type property allowing to set an
IOMMU granule. Values are 4k, 8k, 16k, 64k and host.
This latter indicates the vIOMMU granule will match
the host page size.
A subsequent patch will add such a property to the
virtio-iommu device.

Target-agnostic code can use IGD methods. To allow that, extract

When setting GLIB_VERSION_MAX_ALLOWED to GLIB_VERSION_2_58 or higher,
glib adds type safety checks to the g_steal_pointer() macro. This
triggers errors in the ct3_build_cdat_entries_for_mr() function which
uses the g_steal_pointer() for type-casting from one pointer type to
the other (which also looks quite weird since the local pointers have
all been declared with g_autofree though they are never freed here).
Fix it by using a proper typecast instead. For making this possible, we
have to remove the QEMU_PACKED attribute from some structs since GCC
otherwise complains that the source and destination pointer might
have different alignment restrictions. Removing the QEMU_PACKED should
be fine here since the structs are already naturally aligned. Anyway,
add some QEMU_BUILD_BUG_ON() statements to make sure that we've got
the right sizes (without padding in the structs).
