The CPU manager uses an I/O port and to prevent potential clashes with
assignment for PCI devices ensure that it is allocated by the allocator.

Rather than hardcode the CPU status for all the CPUs instead query from
the CPU manager via the I/O port that is is on via the ACPI tables.
Each CPU device has a _STA method that calls into the CSTA method which
reads and writes the I/O ports via the PRST field which exposes the I/O
port through and OpRegion.
As we only support boot CPUS report that all the CPUs are enabled for
now.

The Linux kernel expects all CPUs, whether they be enabled or disabled
to have an _MAT entry containing the LAPIC details for this CPU with the
enabled bit set to 1 (in the flags.)
In the MADT table the same bit is used to determine if the CPU is
present at boot vs available later.

The comments of vfio kernel module said that individual subindex
interrupts can be disabled using the -1 value for DATA_EVENTFD or
the index can be disabled as a whole with:
flags = (DATA_NONE|ACTION_TRIGGER), count = 0.

This commit introduces a dedicated document describing the device model
supported by cloud-hypervisor VMM.
It needs to be updated anytime a new device will be added in the future.

When adding devices to the guest, and populating the device model, we

The new micro_http package provides a built-in HttpServer wrapper for
