The dynamic linker converts the Linux layout to the AIX layout and is
reentrant so it won't do it a second time if it's already been
converted. In short it work just fine with either register layout.

OTOH, statically linked binaries expect a Linux layout.

Remove code converting the Linux layout to AIX layout so that all
binaries are presented the Linux Layout.

The location tracking interface is used by code shared with qemi-img,
qemu-nbd and qemu-io, so it needs to be available there.  Commit
827b0813 provides it in a rather hamfisted way: it adds a dummy
implementation to qemu-tool.c.

It's cleaner to provide the real thing, and put a few more dummy
monitor functions into qemu-tool.c.

The current default stack limit of 512kB is far too small; a fair
number of gcc testsuite failures (for all guests) are directly
attributable to this.  Using the -s option in every invocation of
the emulator is annoying to say the least.

A reasonable compromise seems to be to honor the system rlimit.
At least on two Linux distributions, this is set to 8MB and 10MB
respectively.  If the system does not limit the stack, then we're
no worse off than before.

At the same time, rename the variable from x86_stack_size and
change the ultimate fallback size from 512kB to 8MB.

Beginning with its introduction, the virtio balloon has had an overflow error
that causes 'info balloon' to misreport the actual memory size when the balloon
itself becomes larger than 4G.  Use a cast when converting dev->actual from
pages to kB to prevent overflows.

Before:
(qemu) info balloon
balloon: actual=5120
(qemu) balloon 1025
(qemu) info balloon
balloon: actual=1025
(qemu) balloon 1024
(qemu) info balloon
balloon: actual=5120

After:
(qemu) info balloon
balloon: actual=5120
(qemu) balloon 1025
(qemu) info balloon
balloon: actual=1025
(qemu) balloon 1024
(qemu) info balloon
balloon: actual=1024

As soon as virtio-pci.c gets compiled and used on S390 the internal qdev magic
gets confused and tries to give us PCI devices instead of S390 virtio devices.

Since we don't have PCI on S390, we can safely not compile virtio-pci at all.

In order to do this I added a new config option "CONFIG_VIRTIO_PCI" that I
enabled for every platform except S390. Thanks to this the change should be a
complete nop for every other platform.

Some targets (e.g. Alpha and MIPS64) need to keep 32-bit operands
sign-extended in 64-bit registers (regardless of the "real" sign
of the operand).  For that, we need to be able to distinguish
between a 32-bit load with a 32-bit result and a 32-bit load with
a given extension to a 64-bit result.  This distinction already
exists for the ld* loads, but not the qemu_ld* loads.

Reserve qemu_ld32u for 64-bit outputs and introduce qemu_ld32 for
32-bit outputs.  Adjust all code generators to match.
