This function is called after virtio_load, so all vlan configuration is
lost in migration case.
Just allow all the vlan-tagged packets if vlan is not configured, and
trust device reset to clear all filtered vlans.

To use the generic device the user will need to provide the config
region size via the command line. We also add a notifier so the guest
can be pinged if the remote daemon updates the config.
With these changes:
-device vhost-user-device-pci,virtio-id=41,num_vqs=2,config_size=8
is equivalent to:
-device vhost-user-gpio-pci

In theory we shouldn't need to repeat so much boilerplate to support
vhost-user backends. This provides a generic vhost-user-base QOM
object and a derived vhost-user-device for which the user needs to
provide the few bits of information that aren't currently provided by
the vhost-user protocol. This should provide a baseline implementation
from which the other vhost-user stub can specialise.

In order to make vhost-vdpa.c a target-agnostic source unit,
we need to remove the TARGET_PAGE_SIZE / TARGET_PAGE_MASK /
TARGET_PAGE_ALIGN uses. TARGET_PAGE_SIZE will be replaced by
the runtime qemu_target_page_size(). The other ones will be
deduced from TARGET_PAGE_SIZE.
Since the 3 macros are used in 3 related functions (sharing
the same call tree), we'll refactor them to only depend on
TARGET_PAGE_MASK.
Having the following call tree:
vhost_vdpa_listener_region_del()
-> vhost_vdpa_listener_skipped_section()
-> vhost_vdpa_section_end()
The first step is to propagate TARGET_PAGE_MASK to
vhost_vdpa_listener_skipped_section().

current code sets PCI_SEC_LATENCY_TIMER to RW, but for

pci express spec which says:
This register does not apply to PCI Express. It must be read-only
and hardwired to 00h. For PCI Express to PCI/PCI-X Bridges, refer to the
[PCIe-to-PCI-PCI-X-Bridge] for requirements for this register.
also, fix typo in comment where it's made writeable - this typo
is likely what prevented us noticing we violate this requirement
