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

to ensure we have the new 'incremental' parameter for the
proxmox_backup_register_image and proxmox_backup_register_image_async
functions available

Add trailing newline to two error messages, and drop an extra
unconditional `qdict_put_str(options, "driver", format);`
Besides that it's just formatting.

Move qemu_savevm_state_{header,setup} into the main loop and
the rest of the iteration into a coroutine. The former need
to lock the iothread (and we can't unlock it in the
coroutine), and the latter can't deal with being in a
separate thread, so a coroutine it must be.

Release the lock on qemu_coroutine_yield, so coroutines don't
deadlock.
