This is necessary for multi-disk backups where not all jobs are
immediately started after they are created. QEMU commit
06e0a9c16405c0a4c1eca33cf286cc04c42066a2 did already part of the work,
ensuring that new writes after job creation don't pass through to the
backup, but not yet for the MIRROR_SYNC_MODE_BITMAP case which is used
for PBS.

This drops debian/patches/pve/0005-PVE-Config-smm_available-false.patch
(and renumbers the remaining patches)
From what I could gather, this patch was originally added
due to issues with old kernels. Now we have users which
seem to run into issues *with* the patch.
All this does is toggle an option, and it's available via a
qemu CLI option anyway, so if dropping this patch causes
issues for some people we can just add an option to
qemu-server & UI control smm explicitly.

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

...instead of having them in the middle of the backup related patches.
These might (hopefully) become upstream at some point as well.
