The logic to handle AArch64 system event was: SHUTDOWN and RESET were
all treated as RESET.
Now we handle them differently:
- RESET event will trigger Vmm::vm_reboot(),
- SHUTDOWN event will trigger Vmm::vm_shutdown().

Now Vcpu::run() returns a boolean value to VcpuManager, indicating
whether the VM is going to reboot (false) or just continue (true).
Moving the handling of hypervisor VCPU run result from Vcpu to
VcpuManager gives us the flexibility to handle more scenarios like
shutting down on AArch64.

Set the test case test_snapshot_restore X86 only, instead of excluding
it from test command line.
The command line option was added because we used to support migration
with Virtio-MMIO, but not Virtio-PCI.

Rather than filling the guest memory from a file at the point of the the
guest memory region being created instead fill from the file later. This
simplifies the region creation code but also adds flexibility for
sourcing the guest memory from a source other than an on disk file.

Tests not ported include 1) the ones that start guest VMs without
network (e.g. test_net_hotplug, test_initramfs), 2) test_vfio that
involves l2 guest. Also, some tests that use bionic guest image are
given extended timeout (120s) for 'wait_vm_boot'.

Instead of waiting blindly with fixed amount of sleeping time, we can
use the `wait-timeout` crate to explicitly wait VM shutdown (with a
timeout). It can reduces the execution time of some tests
substantially. Also, this patch increases the `shutdown` timeout for
'test_reboot', which should fix the recent sporadic failures on this
test.

Instead of blindly waiting for 20-40s for the guest VM to boot, this
patch waits the notification from the guest VM explicitly by using a
simple TcpListener on the host and a custom systemd service in the
guest.
This patch also ported few tests to use this new machanism, while more
tests are to be ported.

Use a Result<> type with an error to simplify the code in start_vmm().
This will also make it easier to add cleanup funtionality.

This gives a nicer user experience and this error can now be used as the
source for other errors based off this.

Any occurrence of of a variable containing `ext_region` is replaced with
the less confusing name `saved_region`. The point is to clearly identify
the memory regions that might have been saved during a snapshot, while
the `ext` standing for `external` was pretty unclear.

In the context of saving the memory regions content through snapshot,
using the term "backing file" brings confusion with the actual backing
file that might back the memory mapping.
To avoid such conflicting naming, the 'backing_file' field from the
MemoryRegion structure gets replaced with 'content', as this is
designating the potential file containing the memory region data.

Use GuestRegionMmap::read_exact_from() to ensure that all of the file is
read into the guest. This addresses an issue where
GuestRegionMmap::read_from() was only copying the first 2GiB of the
memory and so lead to snapshot-restore was failing when the guest RAM
was 2GiB or greater.
This change also propagates any error from the copying upwards.
