This patch adds required infrastructure for the new security model.

- A new configure option for attr/xattr.
- if CONFIG_VIRTFS will be defined if both CONFIG_LINUX and CONFIG_ATTR defined.
- Defines routines related to both security models.

The ABI-specific types used by linux_binprm and image_info
are different after forcing TARGET_ABI32 on.  Which means
that the parameters that load_elf_binary_multi sees are not
those that loader_exec passed.  This is inherently broken
and is more trouble than it's worth fixing.

This allows limited use of kvm functions (which will return ENOSYS)
even in once-compiled modules.  The patch also improves a bit the error

Commit b305b9d7 made building of virtio-pci
conditional and not enabled on S390x, because it collides with the S390 bus.

Commit 087431d1 accidentially reverted that
behavior, breaking S390x again.

So here's a follow-up patch disabling building of virtio-pci on S390x again.

This unbreaks the S390x target.

event notifiers are slightly generalized eventfd descriptors. Current
implementation depends on eventfd because vhost is the only user, and
vhost depends on eventfd anyway, but a stub is provided for non-eventfd
case.

We'll be able to further generalize this when another user comes along
and we see how to best do this.
