update submodule and patches to 7.0.0

Only very minor changes needed:
* Most patches in extra (or some version of them) are part of 7.0.0.
* aio_set_fd_handler got an extra parameter, but can just pass NULL
  like we did for the related 'poll' parameter. See QEMU commit
  826cc32423db2a99d184dbf4f507c737d7e7a4ae for more.
* Add include for qemu/memalign.h in vma.c and vma-writer.c.
* Add reverts for fixups of already reverted 0347a8fd4c ("block/rbd:
  implement bdrv_co_block_status") that came in with 7.0.0. Those
  fixups are not enough, see Proxmox bugzilla #4047.
* Two trivial context changes for bitmap-mirror patches.
* block_int.h got split up into multiple headers.
* Some context changes in configure and meson.build.
* Used the oppurtunity to squash fixup of bdrv_backuo_dump_create typo
  in a later patch into the patch introducing the function (had to
  move code to new header during rebase).
