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

No major semantic changes, mostly just deprecations and changed function
signatures. Drop the extra/ patches, as they have been applied upstream.
The added extra/ patch was accepted upstream[0] but has not been picked
up for 5.1. It is required for non-4M aligned backups to work with PBS.
