vmstate, memory: decouple vmstate from memory API

Currently creating a memory region automatically registers it for
live migration. This differs from other state (which is enumerated
in a VMStateDescription structure) and ties the live migration code
into the memory core....

ivshmem: fix PCI BAR2 registration during initialization

Ivshmem cannot work, and the command lspci cannot show ivshmem BAR2 in the guest.
As for pci_register_bar(), parameter MemoryRegion should be s->bar instead of s->ivshmem.

ivshmem: use migration blockers to prevent live migration in peer mode (v2)

Now when you try to migrate with ivshmem, you get a proper QMP error:

(qemu) migrate tcp:localhost:1025
Migration is disabled when using feature 'peer mode' in device 'ivshmem'

Add endianness as io mem parameter

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.

This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose...

hw/ivshmem.c don't check for negative values on unsigned data types

There is no need to check for dest < 0 or vector >= 0 as both are
