add stable patches for 8.0.0

Changes to other patches are all just metadata/context changes except
for pvebackup_co_prepare() needing to call bdrv_co_unref() rather than
bdrv_unref(), because it is a coroutine itself. This is documented in
d6ee2e324e ("block-coroutine-wrapper: Introduce no_co_wrapper"). The
change is necessary, because one of the stable fixes converts
bdrv_unref and blk_unref into no_co_wrappers (in preparation for a
second patch to fix a hang with the block resize QMP command).
