it ships a symbol file now, so it can be auto-generated based on the
build-dep and usage.

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

Fixes vma restore when the target is an iSCSI storage which expects that
initiatorname. Also avoids the need to always explicitly set the initiatorname
in PVE code, thus fixing moving efidisks from and to such iSCSI storages.

jemalloc does not play nice with our Rust library (proxmox-backup-qemu),
specifically it never releases memory allocated from Rust to the OS.
This leads to a problem with larger caches (e.g. for the PBS block driver).
It appears to be related to this GitHub issue:
https://github.com/jemalloc/jemalloc/issues/1398
The background_thread solution seems weirdly hacky, so let's disable
jemalloc entirely for now.

bump build-dependency on libproxmox-backup-qemu0-dev with version query

The idea in general is to migrate all the state, which is small for
us, in a single step once. But, QEMU only calls save state if we
return active true.
Hardcoding is-active to return true, like done initially, makes the
migration freeze, as QEMU thinks this is never done, and only stops
calling us and finishes after a few seconds.
So, add a state with an "active" boolean, set to true when
initializing a migration, and set it to false when the state was
saved.

With the transaction patches, patch 0026-PVE-Backup-modify-job-api.patch
is no longer necessary, so drop it and rebase all following patches on
top.

Prints QEMU errors that occur *after* the "-daemonize" fork to the
systemd journal, instead of pushing them into /dev/null like before.

this is needed for template backups with PBS until we have the backup
equivalent of 'pbs-restore'.

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.

fixes an assertion failure in qemu network packet processing, which can
lead to DOS'ing the qemu process on the host. this affects 'e1000e' and
'vmxnet3' network devices.
patch is cherry-picked from the commit mentioned in the oss-security email.

"PVE backup: rename incremental to use-dirty-bitmap" merged two
variables (use_dirty_bitmap and incremental) into one, but they served
two different purposes. Rename the original use_dirty_bitmap to
"expect_only_dirty" so the new one doesn't conflict, and rework "PVE:
use proxmox_backup_check_incremental" around that semantic.
In practice, this had the effect that only one disk at a time would
have a bitmap added, as after the first "use_dirty_bitmap" would be set
to one and the rest would behave as if the QMP parameter of the same
name was unset.

* rename "incremental" param to "use-dirty-bitmap", avoids confusion
as the backup can be incrementally also with that param set to
false.
* use new proxmox_backup_check_incremental
* fix setting dirty counter and adapt to new connect API semantic
