This patch introduces a new socket for QEMU, called multi-socket. This
socket allows multiple QEMU instances to communicate by sharing messages
and file descriptors.
A socket can be instantiated with the following parameters:

From: Baptiste Reynal
This patch introduces a shared memory backend, allowing to share memory
between a master and many slaves.
The memory is implemented using hugetlbfs, and relies on the
multi-socket backend to share informations (size and offset for the
slaves).
Instantiation on the master:

This patch introduces the Interrupt Distribution Module (IDM) device for ARM,
x86 and X86_64 architectures, as the only currently supported ones.
The IDM device is used both as and Inter-processor interrupt routing device,

that depends on the machine model

Send the shm for the dirty pages logging if the backend supports
VHOST_USER_PROTOCOL_F_LOG_SHMFD. Wait for a reply to make sure
the old log is no longer used.

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 function is a precondition for most vhost-user tests.

This patch adds a menu item called "Run Custom Script".
When the user selects it, a open-file dialog has the
user select a text file with the custom scripts to run.
This allows for virtually unlimited expandability. All
monitor commands should
