Stefan Reiter 8dca018b68 udpate and rebase to QEMU v6.0.0
Mostly minor changes, bigger ones summarized:
* QEMU's internal backup code now uses a new async system, which allows
  parallel requests - the default max_workers settings is 64, I chose
  less, since 64 put enough stress on QEMU that the guest became
  practically unusable during the backup, and 16 still shows quite a
  nice measureable performance improvement. Little code changes for us
  though.
* 'malformed' QAPI parameters/functions are now a build error (i.e.
  using '_' vs '-'), I chose to just whitelist our calls in the name of
  backwards compatibility.
* monitor OOB race fix now uses the upstream variant, cherry-picked from
  origin/master since it's not in 6.0 by default
* last patch fixes a bug with snapshot rollback related to the new yank
  system

Subject: [PATCH] PVE: [Config] block/file: change locking default to off
'auto' only checks whether the system generally supports OFD
locks but not whether the storage the file resides on
supports any locking, causing issues with NFS.
