Fiona Ebner a573598321 update patches and submodule to QEMU stable 7.2.10
Many stable fixes came in since the last bump, a few of which were
actually already present. Notable ones not yet present include a few
guest-triggerable assert fixes, some AHCI/IDE fixes (including the fix
for bug #2784), TGC fixes for i386 and ARM, VirtIO fixes, fix to avoid
VNC clipboard denial-of-service.

The reentrancy patches that landed upstream/stable were a newer
version than the ones backported initially here, so it was necessary
to explicitly drop them before rebase (which then picked up the
upstream version).

There were no other conflicts.

Subject: [PATCH] mirror: move some checks to qmp
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
and assert the passing conditions in block/mirror.c. while incremental
mode was never available for drive-mirror, it makes the interface more
uniform w.r.t. backup block jobs.
