The pci_register_device() call in PCI nic initialization routines can
fail. Handle this failure and propagate a meaningful error message to
the user instead of generating a SEGV.

According to PnP specification, Appendix B, Option ROMs
that support DDIM (device driver initialization model) should
have their memory space writeable.
KVM deviates from us here, by removing the IO_MEM_ROM flag,
to allow for PCI option ROMs (they require DDIM). However,
there's absolutely no reason we can't do the same.

There are reasonable test cases where a read must span areas that are not
uniformly filled with one pattern but contains several parts. This makes -P
useless for them currently.
Introducing additional options which determine the part of the read data that
should be verified with the given pattern allows to check such reads.

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
