[pve-devel] [PATCH qemu-server 4/5] introduce QMPHelpers module

[Fiona Ebner]

moving qemu_{device,object}{add,del} helpers there for now.

In preparation to remove the cyclic include of PVE::QemuServer in the
memory module and generally for better modularity in the future.

No functional change intended.
