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

- still works if the build dir is not the src dir
- use find instead of *.c block/*.c etc...

AUDIO_PT only changes LDFLAGS to include -pthread, but it change it in
Makefile, and audio files are linked only on Makefile.target

Now we have to variables: QEMU_CFLAGS: flags without which we can't compile
CFLAGS: "-g -O2"
We can now run:
make CFLAGS="-fbar" foo.o
make CFLAGS="" foo.o
make CFLAGS="-O3" foo.o
And it all should work.

This is a new block driver written from scratch
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

Message-Id:
This patch is a major overhaul of the device properties. The properties
are saved directly in the device state struct now, the linked list of
property values is gone.
Advantages:
* We don't have to maintain the list with the property values.
* The value in the property list and the value actually used by
the device can't go out of sync any more (used to happen for
the pci.devfn == -1 case) because there is only one place where
the value is stored.
* A record describing the property is required now, you can't set
random properties any more.
There are bus-specific and device-specific properties. The former
should be used for properties common to all bus drivers. Typical
use case is bus addressing, i.e. pci.devfn and i2c.address.
Properties have a PropertyInfo struct attached with name, size and
function pointers to parse and print properties. A few common property
types have PropertyInfos defined in qdev-properties.c. Drivers are free
to implement their own very special property parsers if needed.
Properties can have default values. If unset they are zero-filled.
