Build uset targers as true PIE if user want to keep qemu
self-virtualizable.

v5:
  - Split into to patches: drop link hack and add PIE support
  - do not build PIE by default and drop toolchain check

v4:
  - Add test for toolchain if it has proper PIE support

v3:
  - One more pice of the hack was removed
  - Description updated

v2:
  - Add configure options do enable/disable PIE for usermode targets.
    Disabling can be useful if you build uswing toolchain which has
    broken PIE support. PIE for usermode targets enabled by default.

* Add SCSIBus.
 * Add SCSIDeviceInfo, move device callbacks here.
 * add qdev/scsi helper functions.
 * convert drivers.

Adding scsi disks via -device works now, i.e. you can do:

 -drive id=sda,if=none,...
 -device lsi
 -device scsi-disk,drive=sda

legacy command lines (-drive if=scsi,...) continue to work.

QDict is a high-level dictionary data type that can be used to store a
collection of QObjects. A unique key is associated with only one
QObject.

The following functions are available:

- qdict_new()    Create a new QDict
- qdict_put()    Add a new 'key:object' pair
- qdict_get()    Get the QObject of a given key
- qdict_del()    Delete a 'key:object' pair
- qdict_size()   Return the size of the dictionary
- qdict_haskey() Check if a given 'key' exists

Some high-level helpers to operate on QStrings and QInts objects
are also provided.

QString is a high-level data type that can be used to represent
C strings.

The following functions are available:

- qstring_from_str() Create a new QString
- qstring_get_str()  Get a pointer to the stored string

Note that qstring_get_str() is too low-level for a data type like
this, but it's interesting for quick read-only accesses.

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.

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
