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 Signed-off-by: Stefan Reiter <s.reiter@proxmox.com>
