My commit ea053add70 broke -net socket by
overwriting an intermediate buffer in the added check_param. Fix this
by switching check_param to automatic buffer allocation and release, ie.
callers no longer have to worry about providing a scratch buffer.

If the KVM MMU is asynchronous (kernel does not support MMU_NOTIFIER),
we have to avoid COW for the guest memory. Otherwise we risk serious
breakage when guest pages change there physical locations due to COW
after fork. Seen when forking smbd during runtime via -smb.

Format must be identical to the guest surface, we can't work with
the 32 bpp used by the default surface allocator.
Without this patch vnc doesn't get the conversions right when sending
pixel data to the client. The bug triggers if
(a) the client doesn't support WMVi, and
(b) the guest screen depth is != 32 bpp.

Add support for SG_IO passthru (packet commands) to the virtio-blk
backend. Conceptually based on an older patch from Hannes Reinecke
but largely rewritten to match the code structure and layering in
virtio-blk.
Note that currently we issue the hose SG_IO synchronously. We could
easily switch to async I/O, but that would required either bloating
the VirtIOBlockReq by the size of struct sg_io_hdr or an additional
memory allocation for each SG_IO request.

There is no need to reject an unaligned memory region registration if
the region will be I/O memory and it will not split an existing KVM
slot. This fixes KVM support on PPC.
