QInt is a high-level data type that can be used to represent integers,
internally it stores an int64_t value.

The following functions are available:

- qint_from_int() Create a new QInt
- qint_get_int()  Get the stored integer

Now that do have a nicer interface to work against we can add Linux native
AIO support.  It's an extremly thing layer just setting up an iocb for
the io_submit system call in the submission path, and registering an
eventfd with the qemu poll handler to do complete the iocbs directly
from there.

This started out based on Anthony's earlier AIO patch, but after
estimated 42,000 rewrites and just as many build system changes
there's not much left of it.

To enable native kernel aio use the aio=native sub-command on the
drive command line.  I have also added an option to qemu-io to
test the aio support without needing a guest.

As requested by Anthony make pthreads mandatory.  This means we will always
have AIO available on posix hosts, and it will also allow enabling the I/O
thread unconditionally once it's ready.

Implement migration via unix sockets.  While you can fake this using
exec and netcat, this involves forking another process and is
generally not very nice.  By doing this directly in qemu, we can avoid
the copy through the external nc command.  This is useful for
implementations (such as libvirt) that want to do "secure" migration;
we pipe the data on the sending side into the unix socket, libvirt
picks it up, encrypts it, and transports it, and then on the remote
side libvirt decrypts it, dumps it to another unix socket, and
feeds it into qemu.

The implementation is straightforward and looks very similar to
migration-exec.c and migration-tcp.c

to support the VDI format in QEMU.

VDI is the native format used by Innotek / SUN VirtualBox.

Latest changes:

* stripped down version
  (code for synchronous operations and experimental code removed)

* don't open VDI snapshot images (with uuid_link or uuid_parent)

* modified vdi_aio_cancel
