6650b7100b win32: Set unbuffered stdout
Win32 does not support line-buffering, but it allows
unbuffered output.

Unbuffered output is a good approximation. For typical output
statements which usually end with '\n', it's even identical.

Buffered output is unusable for program traces because of
its large delay.

ea9c16989b trace: Use TP_PROTO() and TP_ARGS() for LTTng UST
The LTTng UserSpace Tracer formerly used TPPROTO() and TPARGS() instead
of TP_PROTO() and TP_ARGS() like the kernel uses.  This has been changed
so QEMU needs to follow.

I am not aware of a graceful way of making the transition but since no
one complained that the UST build is broken, it should be fine to just
switch over without compatibility for old UST headers.  The newer UST
headers are shipping in distro packages so it is realistic to make this
change now.

010ec62934 eepro100: Add support for multiple individual addresses (multiple IA)
I reviewed the latest sources of Linux, FreeBSD and NetBSD.
They all reset the multiple IA bit (multi_ia in BSD) to zero,
but I did not find code which sets this bit to one
(like it is done by some routers).

Running Windows guests also did not set this bit.

Intel's Open Source Software Developer Manual does not
give much information on the semantics related to this bit,
so I had to guess how it works. The guess was good enough
to make the router emulation work.

Related changes in this patch:
* Update naming and documentation of the internal hash register.
  It is not limited to multicast, but also used for multiple IA.
* Dump complete configuration register when debug traces are enabled.
* Debug output when multiple IA bit is set during CmdConfigure.
* Debug output when frames are received because multiple IA bit is set,
  or when they are ignored although it is set.

a083a89d72 net: delay freeing peer host device
With -netdev, virtio devices present offload
features to guest, depending on the backend used.
Thus, removing host netdev peer while guest is
active leads to guest-visible inconsistency and/or crashes.

As a solution, while guest (NIC) peer device exists,
we prevent the host peer from being deleted.
This patch does this by adding peer_deleted flag in nic state:
if host device is going away while guest device
is around, set this flag and keep a shell of
the host device around for as long as guest device exists.

The link is put down so all packets will get discarded.

At the moment, management can detect that device deletion
is delayed by doing info net. As a next step, we shall add
commands that control hotplug/unplug without
removing the device, and an event to report that
guest has responded to the hotplug event.

    __attribute__ ((format (gnu_printf, 1, 2)))

because QEMU always uses standard format strings (even with mingw32).

The patch replaces format attribute printf / __printf__ by macro
GCC_FMT_ATTR which uses gnu_printf if supported.

It also removes an #ifdef __GNUC__ (not needed any longer).
