Use blk_unref to drop the last reference, which will close the block
backend and flush all caches and outstanding writes.
This is especially important for restoring to Ceph, as the userspace
librbd caches will not be flushed if the application exits immediately,
leading to potentially incomplete restores.

Lots of patches touched and some slight changes to the build process
since QEMU switched to meson as their build system. Functionality-wise
very little rebasing required.
New patches introduced:
* pve/0058: to fix VMA backups and clean up some code in general with
new 5.2 features now available to us (namely coroutine-enabled QMP).
* extra/0002: don't build man pages for guest agent when disabled
* extra/0003: fix live-migration with hugepages
* 0017 and 0018 are adjusted to fix snapshot abort and improve
snap performance a bit
