* 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.

A out-of-bounds heap buffer access issue was found in the SLiRP
networking implementation of the QEMU emulator. It occurs in tcp_emu()
routine while emulating IRC and other protocols due to unsafe usage of
snprintf(3) function.
A user/process could use this flaw to crash the Qemu process on the host
resulting in DoS or potentially execute arbitrary code with privileges
of the QEMU process on the host.

this effects our vncproxy. dominik and me tested if the issue is present
on our branch and it appears that it is.
in essence when we disconnect from a vnc connection, the memory isn't
free'd afterwards which causes the qemu process to use more and more
memory with each disconnect, which could lead to a dos scenario.
we tested the patch and it seems to mitigate the problem.
