Fiona Ebner 7882afe30d update submodule and patches to QEMU 9.1.2
Notable changes, most interestingly the two build system changes:

* avoid making 'migration' target depend on 'libproxmox_backup_qemu':

  Having pbs-state.c be part of the 'migration_files' makes the
  'migration' target depend on 'libproxmox_backup_qemu'. Adding the
  dependency to 'migration' and 'libmigration' would not be enough
  however, because pbs-state.c depends on savevm.c (for
  register_savevm_live()), and savevm.c is not itself part of the
  'migration_files' and would need to be moved too. Otherwise, linking
  the 'test-xbzrle' unit test is broken. Instead, don't declare
  pbs-state.c to be part of the 'migration_files'.

* meson: pbs-restore + vma: add qemuutil dependency explicitly

  Both pbs-restore and vma use "qemu/osdep.h" so the dependency is
  present. Being explicit is required after commit 414b180d42 ("meson:
  Pass objects and dependencies to declare_dependency()").

* QAPI docs "Notes:" to ".. note::" conversion following commit
  d461c27973 ("qapi: convert "Note" sections to plain rST").

* Removal of QERR_* macros following commit
  a95921f171 ("qapi: Inline and remove QERR_DEVICE_HAS_NO_MEDIUM
  definition") and friends.

* Signature change for .save_setup callbacks following commit
  01c3ac681b ("migration: Add Error** argument to .save_setup()
  handler").

* Removal of separate .bdrv_file_open callbacks following commit
  44b424dc4a ("block: remove separate bdrv_file_open callback")

* Adapt dirty bitmap migration error handling following commit
  dd03167725 ("migration: Add Error** argument to
  add_bitmaps_to_list()")

* Adapt savevm async to removed block migration following commit
  eef0bae3a7 ("migration: Remove block migration")

Subject: [PATCH] alloc-track: error out when auto-remove is not set
Since replacing the node now happens in the stream job, where the
option cannot be read from (it's internal to the driver), it will
always be treated as on.
qemu-server will always set it, make sure to have other users notice
the change (should they even exist). The option can be fully dropped
in the future while adding a version guard in qemu-server.
