  intel_iommu: Add support for translation for devices behind bridges

- Use a hash table indexed on bus pointers to store information about buses
  instead of using the bus numbers.
  Bus pointers are stored in a new VTDBus struct together with the vector
  of device address space pointers indexed by devfn.
- The bus number is still used for lookup for selective SID based invalidate,
  in which case the bus number is lazily resolved from the bus hash table and
  cached in a separate index.

  net: don't set native endianness

commit 5be7d9f1b1452613b95c6ba70b8d7ad3d0797991
    vhost-net: tell tap backend about the vnet endianness
makes vhost net always try to set LE - even if that matches the
native endian-ness.

This makes it fail on older kernels on x86 without TUNSETVNETLE support.

To fix, make qemu_set_vnet_le/qemu_set_vnet_be skip the
ioctl if it matches the host endian-ness.

  util: add linux-only memfd fallback

Implement memfd_create() fallback if not available in system libc.
memfd_create() is still not included in glibc today, atlhough it's been
available since Linux 3.17 in Oct 2014.

memfd has numerous advantages over traditional shm/mmap for ipc memory
sharing with fd handler, which we are going to make use of for
vhost-user logging memory in following patches.

The next patches are going to introduce helpers to use best practices of
memfd usage and provide some compatibility fallback. memfd.c is thus
temporarily useless and eventually empty if memfd_create() is provided
by the system.

While doing this, I found that "unsigned long long" and "uint64_t" were
used interchangeably and causing compilation warnings, using uint64_t
instead, as the vhost & protocol specifies.

  vhost user: add support of live migration

Some vhost user backends are able to support live migration.
To provide this service the following features must be added:
1. Add the VIRTIO_NET_F_GUEST_ANNOUNCE capability to vhost-net when netdev
   backend is vhost-user.
2. Provide a nop receive callback to vhost-user.
   This callback is called by:
    *  qemu_announce_self after a migration to send fake RARP to avoid network
       outage for peers talking to the migrated guest.
   - For guest with GUEST_ANNOUNCE capabilities, guest already sends GARP
     when the bit VIRTIO_NET_S_ANNOUNCE is set.
     => These packets must be discarded.
   - For guest without GUEST_ANNOUNCE capabilities, migration termination
     is notified when the guest sends packets.
     => These packets can be discarded.
    * virtio_net_tx_bh with a dummy boot to send fake bootp/dhcp request.
      BIOS guest manages virtio driver to send 4 bootp/dhcp request in case of
      dummy boot.
      => These packets must be discarded.

  vhost user: add rarp sending after live migration for legacy guest

A new vhost user message is added to allow QEMU to ask to vhost user backend to
broadcast a fake RARP after live migration for guest without GUEST_ANNOUNCE
capability.

This new message is sent only if the backend supports the new
VHOST_USER_PROTOCOL_F_RARP protocol feature.
The payload of this new message is the MAC address of the guest (not known by
the backend). The MAC address is copied in the first 6 bytes of a u64 to avoid
to create a new payload message type.

This new message has no equivalent ioctl so a new callback is added in the
userOps structure to send the request.

Upon reception of this new message the vhost user backend must generate and
broadcast a fake RARP request to notify the migration is terminated.

  vhost: set the correct queue index in case of migration with multiqueue

When a live migration is started the log address to mark dirty pages is provided
to the vhost backend through the vhost_dev_set_log function.
This function is called for each queue pairs but the queue index is wrongly set:
always set to the first queue pair. Then vhost backend lost descriptor addresses
of the queue pairs greater than 1 and behaviour of the vhost backend is
unpredictable.

The queue index is computed by taking account of the vq_index (to retrieve the
queue pair index) and calling the vhost_get_vq_index method of the backend.

  hw/isa/lpc_ich9: inject the SMI on the VCPU that is writing to APM_CNT

Commit 4d00636e97b7 ("ich9: Add the lpc chip", Nov 14 2012) added the
ich9_apm_ctrl_changed() ioport write callback function such that it would
inject the SMI, in response to a write to the APM_CNT register, on the
first CPU, invariably.

Since this register is used by guest code to trigger an SMI synchronously,
the interrupt should be injected on the VCPU that is performing the write.

apm_ioport_writeb() is the .write callback of the "apm_ops"
MemoryRegionOps [hw/isa/apm.c]; it is parametrized to call
ich9_apm_ctrl_changed() by ich9_lpc_init() [hw/isa/lpc_ich9.c], via
apm_init(). Therefore this change affects no other board.

ich9_generate_smi() is an unrelated function that is called by the TCO
watchdog; a watchdog is likely in its right to (asynchronously) inject
interrupts on the first CPU only.

This patch allows the combined edk2/OVMF SMM driver stack to work with
multiple VCPUs on TCG, using both qemu-system-i386 and qemu-system-x86_64.
