The GTK 3.0 release was made in Feb, 2011:

  https://blog.gtk.org/2011/02/10/gtk-3-0-released/

That will soon be 7 years ago, which is enough time to consider
the 3.x series widely supported.

Thus we deprecate the GTK 2.x support, which will allow us to
delete it in the last release of 2018. By this time, GTK 3.x
will be almost 8 years old.

The GICv2 specification says that reserved register addresses
must RAZ/WI; now that we implement external abort handling
for Arm CPUs this means we must return MEMTX_OK rather than
MEMTX_ERROR, to avoid generating a spurious guest data abort.

Refactor disas_thumb2_insn() so that it generates the code for raising
an UNDEF exception for invalid insns, rather than returning a flag
which the caller must check to see if it needs to generate the UNDEF
code. This brings the function in to line with the behaviour of
disas_thumb_insn() and disas_arm_insn().

Our copy of the nwfpe code for emulating of the old FPA11 floating
point unit doesn't check the coprocessor number in the instruction
when it emulates it.  This means that we might treat some
instructions which should really UNDEF as being FPA11 instructions by
accident.

The kernel's copy of the nwfpe code doesn't make this error; I suspect
the bug was noticed and fixed as part of the process of mainlining
the nwfpe code more than a decade ago.

Add a check that the coprocessor number (which is always in bits
[11:8] of the instruction) is either 1 or 2, which is where the
FPA11 lives.

In current implementation, packet queue flushing logic seem to suffer
from a deadlock like scenario if a packet is received by the interface
before before Rx ring is initialized by Guest's driver. Consider the
following sequence of events:

	1. A QEMU instance is started against a TAP device on Linux
	   host, running Linux guest, e. g., something to the effect
	   of:

	   qemu-system-arm \
	      -net nic,model=imx.fec,netdev=lan0 \
	      netdev tap,id=lan0,ifname=tap0,script=no,downscript=no \
	      ... rest of the arguments ...

	2. Once QEMU starts, but before guest reaches the point where
	   FEC deriver is done initializing the HW, Guest, via TAP
	   interface, receives a number of multicast MDNS packets from
	   Host (not necessarily true for every OS, but it happens at
	   least on Fedora 25)

	3. Recieving a packet in such a state results in
	   imx_eth_can_receive() returning '0', which in turn causes
	   tap_send() to disable corresponding event (tap.c:203)

	4. Once Guest's driver reaches the point where it is ready to
	   recieve packets it prepares Rx ring descriptors and writes
	   ENET_RDAR_RDAR to ENET_RDAR register to indicate to HW that
	   more descriptors are ready. And at this points emulation
	   layer does this:

	   	 s->regs[index] = ENET_RDAR_RDAR;
                 imx_eth_enable_rx(s);

	   which, combined with:

	   	  if (!s->regs[ENET_RDAR]) {
		     qemu_flush_queued_packets(qemu_get_queue(s->nic));
		  }

	   results in Rx queue never being flushed and corresponding
	   I/O event beign disabled.

To prevent the problem, change the code to always flush packet queue
when ENET_RDAR transitions 0 -> ENET_RDAR_RDAR.

ldxp loads two consecutive doublewords from memory regardless of CPU
endianness. On store, stlxp currently assumes to work with a 128bit
value and consequently switches order in big-endian mode. With this
change it packs the doublewords in reverse order in anticipation of the
128bit big-endian store operation interposing them so they end up in
memory in the right order. This makes it work for both MTTCG and !MTTCG.
It effectively implements the ARM ARM STLXP operation pseudo-code:

data = if BigEndian() then el1:el2 else el2:el1;

With this change an aarch64_be Linux 4.14.4 kernel succeeds to boot up
in system emulation mode.

Rename nbd_option and nbd_opt_reply to NBDOption and NBDOptionReply
to correspond to Qemu coding style and other structures here.

Currently the pseries machine sets the compatibility mode for the
guest's cpus in two places: 1) at machine reset and 2) after CAS
negotiation.

This means that if we set or negotiate a compatiblity mode, then
hotplug a cpu, the hotplugged cpu doesn't get the right mode set and
will incorrectly have the full native features.

To correct this, we set the compatibility mode on a cpu when it is
brought online with the 'start-cpu' RTAS call.  Given that we no
longer need to set the compatibility mode on all CPUs at machine
reset, so we change that to only set the mode for the boot cpu.

It's a deprecated dummy device since QEMU v2.6.0. That should have
been enough time to allow the users to update their scripts in case
they still use it, so let's remove this legacy code now.

Currently QEMU does not build on Mac OS 10.6
because of a missing patch in the dtc
subproject. Updating dtc to make the patch
available fixes this problem.
