b8779ddc9e vmm: Create the api socket fd to pass to the http server
Instead of using the http server's method to have it create the
fd (causing the http thread to need to support the socket, bind and
listen syscalls). Create the socket fd in the vmm thread and use the
http server's new method supporting passing in this fd for the api
socket.

767b4f0e59 main: Enable the api-socket to be passed as an fd
To avoid race issues where the api-socket may not be created by the
time a cloud-hypervisor caller is ready to look for it, enable the
caller to pass the api-socket fd directly.

Avoid breaking current callers by allowing the --api-socket path to be
passed as it is now in addition to through the path argument.

0b00442022 vmm: acpi: Allow reading from B0EJ field
Windows guests read this field upon PCI device ejection. Let's make sure
we don't return an error as this is valid. We simply return an empty u32
since the ejection is done right away upon write access, which means
there's no pending ejection that might be reported to the guest.

Here is the error that was shown during PCI device removal:

b92fe648e9 vmm: cpu: Disable KVM_FEATURE_ASYNC_PF_INT in CPUID
By disabling this KVM feature, we prevent the guest from using APF
(Asynchronous Page Fault) mechanism. The kernel has recently switched to
using interrupts to notify about a page being ready, but for some
reasons, this is causing unexpected behavior with Cloud Hypervisor, as
it will make the vcpu thread spin at 100%.

While investigating the issue, it's better to disable the KVM feature to
prevent 100% CPU usage in some cases.

e1cc702327 memory_manager: Fix address range calculation in MemorySlot
The MCRS method returns a 64-bit memory range descriptor. The
calculation is supposed to be done as follows:

max = min + len - 1

However, every operand is represented not as a QWORD but as combination
of two DWORDs for high and low part. Till now, the calculation was done
this way, please see also inline comments:

max.lo = min.lo + len.lo //this may overflow, need to carry over to high
max.hi = min.hi + len.hi
max.hi = max.hi - 1 // subtraction needs to happen on the low part

This calculation has been corrected the following way:

max.lo = min.lo + len.lo
max.hi = min.hi + len.hi + (max.lo < min.lo) // check for overflow
max.lo = max.lo - 1 // subtract from low part

The relevant part from the generated ASL for the MCRS method:
```
Method (MCRS, 1, Serialized)
{
    Acquire (MLCK, 0xFFFF)
    \_SB.MHPC.MSEL = Arg0
    Name (MR64, ResourceTemplate ()
    {
	QWordMemory (ResourceProducer, PosDecode, MinFixed, MaxFixed, Cacheable, ReadWrite,
	    0x0000000000000000, // Granularity
	    0x0000000000000000, // Range Minimum
	    0xFFFFFFFFFFFFFFFE, // Range Maximum
	    0x0000000000000000, // Translation Offset
	    0xFFFFFFFFFFFFFFFF, // Length
	    ,, _Y00, AddressRangeMemory, TypeStatic)
    })
    CreateQWordField (MR64, \_SB.MHPC.MCRS._Y00._MIN, MINL)  // _MIN: Minimum Base Address
    CreateDWordField (MR64, 0x12, MINH)
    CreateQWordField (MR64, \_SB.MHPC.MCRS._Y00._MAX, MAXL)  // _MAX: Maximum Base Address
    CreateDWordField (MR64, 0x1A, MAXH)
    CreateQWordField (MR64, \_SB.MHPC.MCRS._Y00._LEN, LENL)  // _LEN: Length
    CreateDWordField (MR64, 0x2A, LENH)
    MINL = \_SB.MHPC.MHBL
    MINH = \_SB.MHPC.MHBH
    LENL = \_SB.MHPC.MHLL
    LENH = \_SB.MHPC.MHLH
    MAXL = (MINL + LENL) /* \_SB_.MHPC.MCRS.LENL */
    MAXH = (MINH + LENH) /* \_SB_.MHPC.MCRS.LENH */
    If ((MAXL < MINL))
    {
	MAXH += One /* \_SB_.MHPC.MCRS.MAXH */
    }

    MAXL -= One
    Release (MLCK)
    Return (MR64) /* \_SB_.MHPC.MCRS.MR64 */
}
```

Fixes #1800.

9e9aba7c0b CpuManager: Fix MMIO read handling
There are two parts:

- Unconditionally zero the output area. The length of the incoming
  vector has been seen from 1 to 4 bytes, even though just the first
  byte might need to be handled. But also, this ensures any possibly
  unhandled offset will return zeroed result to the caller. The former
  implementation used an I/O port which seems to behave differently from
  MMIO and wouldn't require explicit output zeroing.
- An access with zero offset still takes place and needs to be handled.

Fixes #2437.

5b168f54a6 hyperv: Fix CPU hotadd
The following is from the Hyper-V specification v6.0b.

Cpuid leaf 0x40000003 EDX:

Bit 3: Support for physical CPU dynamic partitioning events is
available.

When Windows determines to be running under a hypervisor, it will
require this cpuid bit to be set to support dynamic CPU operations.

Cpuid leaf 0x40000004 EAX:

Bit 5: Recommend using relaxed timing for this partition. If
used, the VM should disable any watchdog timeouts that
rely on the timely delivery of external interrupts.

This bit has been figured out as required after seeing guest BSOD
when CPU hotplug bit is enabled. Race conditions seem to arise after a
hotplug operation, when a system watchdog has expired.

Closes #1799.

1e11e6789a vmm: device_manager: Factorize passthrough_device creation
There's no need to have the code creating the passthrough_device being
duplicated since we can factorize it in a function used in both cases
(both cold plugged and hot plugged devices VFIO devices).

b06fd80fa9 vmm: device_manager: Use DeviceTree to store PCI devices
Extend and use the existing DeviceTree to retrieve useful information
related to PCI devices. This removes the duplication with pci_devices
field which was internal to the DeviceManager.

c8c3cad8cb vmm: device_manager: Update structure holding PCI IRQs
Make the code a bit clearer by changing the naming of the structure
holding the list of IRQs reserved for PCI devices. It is also modified
into an array of 32 entries since we know this is the amount of PCI
slots that is supported.

e311fd66cd vmm: device_manager: Remove the need for Any
We define a new enum in order to classify PCI device under virtio or
VFIO. This is a cleaner approach than using the Any trait, and
downcasting it to find the object back.
