2013-04-29libqos: Convert fw_cfg values to host endiannessAndreas Färber
The fw_cfg ABI is Little Endian, so byte-swap the generically read byte array to host endianness. This unbreaks the fw_cfg tests on ppc.

2013-04-29virtio-net: unbreak the minix guestJason Wang
Multiqueue patchset conditionally add control vq only when guest negotiate the feature. Though the spec is not clear on this but it breaks the minix guest since it will identify the ctrl vq even if it does not support it. Though this behavior seems a violation on the spec "If the VIRTIO_NET_F_CTRL_VQ feature bit is negotiated, identify the control virtqueue.", to keep the backward compatibility, always add the ctrl vq at end of the queues.

2013-04-29win32: add readv/writev emulationPaolo Bonzini
Commit e9d8fbf (qemu-file: do not use stdio for qemu_fdopen, 2013-03-27) introduced a usage of writev, which mingw32 does not have. Even though qemu_fdopen itself is not used on mingw32, the future-proof solution is to add an implementation of it. This is simple and similar to how we emulate sendmsg/recvmsg in util/iov.c. Some files include osdep.h without qemu-common.h, so move the definition of iovec to osdep.h too, and include osdep.h from qemu-common.h unconditionally (protection against including files when NEED_CPU_H is defined is not needed since the removal of AREG0).
