This patchset is the QEMU-side implementation of a (new) dirty "quota"
based throttling algorithm that selectively throttles vCPUs based on their
individual contribution to overall memory dirtying and also dynamically
adapts the throttle based on the available network bandwidth.
Overview
Introduces a (new) throttling scheme where QEMU defines a limit on the dirty
rate of each vcpu of the VM. This limit is enfored on the vcpus in small
intervals (dirty quota intervals) by allowing the vcpus to dirty only as many
pages in these intervals as to maintain a dirty rate below the set

During my PIIX consolidation work [1] I've noticed that both PIIX models have
quite different pci_slot_get_pirq() implementations. These functions seem to
map PCI INTx pins to input pins of a programmable interrupt router which is
AFAIU board-specific. IOW, board-specific assumptions are
pci_bus_irqs() coupled together the assignment of pci_set_irq_fn and
pci_map_irq_fn to a PCI bus. This coupling gets in the way when the
pci_map_irq_fn is board-specific while the pci_set_irq_fn is device-
specific.
For example, both of QEMU's PIIX south bridge models have different
pci_map_irq_fn's in general seem to be board-specific, and PIIX4's
pci_slot_get_pirq() in particular seems very Malta-specific. So move the
latter to malta.c to 1/ keep the board logic in one place and 2/ avoid
PIIX4 to make assumptions about its board.

Ceph RBD encryption API required specifying the encryption format
for loading encryption. The supported formats were LUKS (v1) and LUKS2.
Starting from Reef release, RBD also supports loading with "luks-any" format,
which works for both versions of LUKS.
This commit extends the qemu rbd driver
Add const modifier to passphrases,
and remove redundant stack variable passphrase_len.

Starting from ceph Reef, RBD has built-in support for layered encryption,
where each ancestor image (in a cloned image setting) can be possibly
encrypted using a unique passphrase.
A new function, rbd_encryption_load2, was added to librbd API.
This new function supports an array of passphrases
