06f57abdf9 pci: vfio: Fix potential mmap leaks from the mmio regions 
We can return prematurely from 'map_mmio_regions()' (e.g. when a mmap call
failed for vfio or 'create_user_memory_region()' failed for vfio-user)
without updating the 'MmioRegion::user_memory_regions' with the
information of previous successful mmaps, which in turn would cause mmap
leaks particularly for the case of hotplug where the 'vmm' thread will
keep running. To fix the issue, let's keep 'MmioRegion::user_memory_regions'
updated right after successful mmap calls.

Fixes: #4068

1108bd1967 pci: vfio: Implement support for sparse mmap 
Reorganizing the code to leverage the same mechanics implemented for
vfio-user and aimed at supporting sparse memory mappings for a single
region.

Relying on the capabilities returned by the vfio-ioctls crate, we create
a list of sparse areas depending if we get SPARSE_MMAP or MSIX_MAPPABLE
capability, or a single sparse area in case we couldn't find any
capability.

The list of sparse areas is then used to create both the memory mappings
in the Cloud Hypervisor address space and the hypervisor user memory
regions.

This allowed for the simplification of the MmioRegion structure.

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').

37521ddff7 pci: vfio: Restore BARs in a more straightforward way 
In case a list of resources is provided to allocate_bars(), it directly
means we're restoring some existing BARs. That's why we shouldn't share
the codepath that creates BARs from scratch as we don't need to interact
with the device to retrieve the information.

Whenever resources are provided, we simply iterate over the list of
possible BAR indexes and create the BARs if the resource could be found.

11e9f43305 vmm: Use new Resource type PciBar 
Instead of defining some very generic resources as PioAddressRange or
MmioAddressRange for each PCI BAR, let's move to the new Resource type
PciBar in order to make things clearer. This allows the code for being
more readable, but also removes the need for hard assumptions about the
MMIO and PIO ranges. PioAddressRange and MmioAddressRange types can be
used to describe everything except PCI BARs. BARs are very special as
they can be relocated and have special information we want to carry
along with them.

as well as allow for custom Serialize/Deserialize implementation for the
PciBdf structure. These custom implementations let us display the PCI
s/b/d/f in a human readable format.

1bd30dc69f vfio-ioctls: Move away from archived crate rust-vmm/vfio-ioctls 
Make sure Cloud Hypervisor relies on upstream and actively maintained
vfio-ioctls crate from the rust-vmm/vfio repository instead of the
deprecated version coming from rust-vmm/vfio-ioctls repository.

cf68f03ab6 pci: vfio: Skip IOBAR allocation on AArch64 
AArch64 does not use IOBAR, and current code of panics the whole VMM if
we need to allocate the IOBAR.

This commit checks if IOBAR is enabled before the arch conditional code
of IOBAR allocation and if the IOBAR is not enabled, we can just skip
the IOBAR allocation and do nothing.

7444c3a0c5 pci: vfio_user: Batch IRQ enabling into batches of 16 
The sendmsg() syscall is limited in the number of fds it can handle.
This number matches that used by the vfio-user library and is
conservative (since we've seen it work with 64 fds.)

Fixes: #3401

to each region, Cloud Hypervisor can decide to mmap a region based on
the presence or absence of MSIX_MAPPABLE. Instead of blindly mmap'ing
the region, we check if the MSI-X table or PBA is present on the BAR,
and if that's the case, we look for MSIX_MAPPABLE.
If MSIX_MAPPABLE is present, we can go ahead and mmap the entire region.
If MSIX_MAPPABLE is not present, we simply ignore the mmap'ing of this
region as it wouldn't be supported.

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.

ed5f25446a pci: vfio: Support mapping BAR containing MSI-X 
In order to get proper performance out of hardware that might be passed
through the VM with VFIO, we decide to try mapping any region marked as
mappable, ignoring the failure and moving on to the next region. When
the mapping succeeds, we establish a list of user memory regions so that
we enable only subparts of the global mapping through the hypervisor.
This allows MSI-X table and PBA to keep trapping accesses from the guest
so that the VMM can properly emulate MSI-X.

0eb78ab177 vmm: Extract PCI related state from DeviceManager 
Move the PCI related state from the DeviceManager struct to a PciSegment
struct inside the DeviceManager. This is in preparation for multiple
segment support. Currently this state is just the bus itself, the MMIO
and PIO config devices and hotplug related state.

The main change that this required is using the Arc<Mutex<PciBus>> in
the device addition logic in order to ensure that
the bus could be created earlier.

0faa7afac2 vmm: Add fast path for PCI config IO port 
Looking up devices on the port I/O bus is time consuming during the
boot at there is an O(lg n) tree lookup and the overhead from taking a
lock on the bus contents.

Avoid this by adding a fast path uses the hardcoded port address and
size and directs PCI config requests directly to the device.

Command line:
target/release/cloud-hypervisor --kernel ~/src/linux/vmlinux --cmdline "root=/dev/vda1 console=ttyS0" --serial tty --console off --disk path=~/workloads/focal-server-cloudimg-amd64-custom-20210609-0.raw --api-socket /tmp/api

PIO exit: 17913
PCI fast path: 17871
Percentage on fast path: 99.8%

perf before:

marvin:~/src/cloud-hypervisor (main *)$ perf report -g | grep resolve
     6.20%     6.20%  vcpu0            cloud-hypervisor    [.] vm_device:🚌:Bus::resolve

perf after:

marvin:~/src/cloud-hypervisor (2021-09-17-ioapic-fast-path *)$ perf report -g | grep resolve
     0.08%     0.08%  vcpu0            cloud-hypervisor    [.] vm_device:🚌:Bus::resolve

The compromise required to implement this fast path is bringing the
creation of the PciConfigIo device into the DeviceManager::new() so that
it can be used in the VmmOps struct which is created before
DeviceManager::create_devices() is called.
