932c8c9713 vmm: Add CPU affinity support
With the introduction of a new option `affinity` to the `cpus`
parameter, Cloud Hypervisor can now let the user choose the set
of host CPUs where to run each vCPU.

This is useful when trying to achieve CPU pinning, as well as making
sure the VM runs on a specific NUMA node.

a4f5ad6076 option_parser: Fix inner bracket support with list of integers
Give the option parser the ability to handle tuples with inner brackets
containing list of integers. The following example can now be handled
correctly "option=[key@[v1-v2,v3,v4]]" which means the option is
assigned a tuple with a key associated with a list of integers between
the range v1 - v2, as well as v3 and v4.

ad521fd4e4 option_parser: Create generic type Tuple
Creates a new generic type Tuple so that the same implementation of
FromStr trait can be reused for both parsing a list of two integers and
parsing a list of one integer associated with a list of integers.

This anticipates the need for retrieving sublists, which will be needed
when trying to describe the host CPU affinity for every vCPU.

def98faf37 vmm, vm-allocator: Introduce an allocator for platform devices
This allocator allocates 64-bit MMIO addresses for use with platform
devices e.g. ACPI control devices and ensures there is no overlap with
PCI address space ranges which can cause issues with PCI device
remapping.

cd9d1cf8fc pci, virtio-devices, vmm: Allocate PCI 64-bit bars per segment
Since each segment must have a non-overlapping memory range associated
with it the device memory must be equally divided amongst all segments.
A new allocator is used for each segment to ensure that BARs are
allocated from the correct address ranges. This requires changes to
PciDevice::allocate/free_bars to take that allocator and when
reallocating BARs the correct allocator must be identified from the
ranges.

For the bus scanning the GED AML code now calls into a PSCN method that

correctly where one GED interrupt is services for two hotplugs on
distinct segments.

The PCIU and PCID field values are now determined by the PSEG field that
is uses to select which segment those values should be used for.
Similarly _EJ0 will notify based on the value of _SEG.
