707cea2182 vmm, devices: Move logging of 0x80 timestamp to its own device 
This is a cleaner approach to handling the I/O port write to 0x80.
Whilst doing this also use generate the timestamp at the start of the VM
creation. For consistency use the same timestamp for the ARM equivalent.

c47e3b8689 gdb: Do not use VmmOps for memory manipulation 
We don't use the VmmOps trait directly for manipulating memory in the
core of the VMM as it's really designed for the MSHV crate to handle
instruction decoding. As I plan to make this trait MSHV specific to
allow reduced locking for MMIO and PIO handling when running on KVM this
use should be removed.

5bd7a1f03c pci: vfio_user: Simplify 'unmap_mmio_regions()' 
Instead of always creating a single large mmap for the MMIO region of a
BAR, we create multiple mmaps for the BARs that need multiple kvm user
memory regions. In this way, we can simplify 'unmap_mmio_regions()' (by
reusing information kept from 'MmioRegion::user_memory_region').

7fe399598d vmm: device_manager: Map MMIO regions to the guest correctly 
To correctly map MMIO regions to the guest, we will need to wait for valid
MMIO region information which is generated from 'PciDevice::allocate_bars()'
(as a part of 'DeviceManager::add_pci_device()').

0c00da1dd8 vfio_user: Split the function for getting device regions 
To prepare the support of region capabilities, this commit factorizes
the `VFIO_USER_DEVICE_GET_REGION_INFO` operation in its own function. In
this process, it also removes the need of the hard-coded arbitrary value
for `vfio_region_info.argsz` (the maximum size of the reply payload).

1dfe4eda5c vmm: Prevent "internal" identifiers being used by user 
For devices that cannot be named by the user use the "__" prefix to
identify them as internal devices. Check that any identifiers provided
in the config do not clash with those internal names. This prevents the
user from creating a disk such as "__serial" which would then cause a
failure in unpredictable manner.

6e101f479c vmm: Ensure hotplugged device identifier is unique 
Whenever a device (virtio, vfio, vfio-user or vdpa) is hotplugged, we
must verify the provided identifier is unique, otherwise we must return
an error.

Particularly, this will prevent issues with identifiers for serial,
console, IOAPIC, balloon, rng, watchdog, iommu and gpio since all of
these are hardcoded by the VMM.

e70bd069b3 vmm: Load kernel asynchronously 
Start loading the kernel as possible in the VM in a separate thread.
Whilst it is loading other work can be carried out such as initialising
the devices.

The biggest performance improvement is seen with a more complex set of
devices. If using e.g. four virtio-net devices then the time to start the
kernel improves by 20-30ms. With the simplest configuration the
improvement was of the order of 2-3ms.
