where there is no good reason to keep them separate. It's a pain
during rebase if there are multiple patches changing the same code
over and over again. This was especially bad for the backup-related
patches. If the history of patches really is needed, it can be
extracted via git. Additionally, compilation with partial application
of patches was broken since a long time, because one of the master key
changes became part of an earlier patch during a past rebase.
If only the same files were changed by a subsequent patch and the
changes felt to belong together (obvious for later bug fixes, but also
done for features e.g. adding master key support for PBS), the patches
were squashed together.
The PBS namespace support patch was split into the individual parts
it changes, i.e. PBS block driver, pbs-restore binary and QMP backup
infrastructure, and squashed into the respective patches.
No code change is intended, git diff in the submodule should not show
any difference between applying all patches before this commit and
applying all patches after this commit.
The query-proxmox-support QMP function has been left as part of the
"PVE-Backup: Proxmox backup patches for QEMU" patch, because it's
currently only used there. If it ever is used elsewhere too, it can
be split out from there.
The recent alloc-track and BQL-related savevm-async changes have been
left separate for now, because it's not 100% clear they are the best
approach yet. This depends on what upstream decides about the BQL
stuff and whether and what kind of issues with the changes pop up.
The qemu-img dd snapshot patch has been re-ordered to after the other
qemu-img dd patches.

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

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

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.
