linux-user: fix page_unprotect when host page size > target page size
When the host page size is bigger that the target one, unprotecting a

- mark all the target pages corresponding to the host page as writable

linux-user/ia64: workaround ia64 strangenesses
ia64 has some strangenesses that need to be workaround:
- it has a __clone2() syscall instead of the using clone() one, with
different arguments, and which is not declared in the usual headers.
- ucontext.uc_sigmask is declared with type long int, while it is
actually of type sigset_t.
- uc_mcontext, uc_sigmask, uc_stack, uc_link are declared using #define,
which clashes with the target_ucontext fields. Change their names to
tuc_*, as already done for some target architectures.

balloon: Fix overflow when reporting actual memory size
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

target-s390: Don't compile in virtio-pci
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.

tcg: Disambiguate qemu_ld32u with 32-bit and 64-bit outputs.
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.
