When converting from hx to texi format, hxtool (or to be
more precise sh which interprets hxtool) used standard
shell expansion of wildcards while writing lines to the
output.

Thus, something like "Password: ********"
looked very different in the generated documentation.

The patch disables this unwanted wildcard expansion.

We want to do (at least) two things to the virtio-balloon device:
suppress it, and control its PCI address.  Option -no-virtio-balloon
lets us do only the former.  To get the latter, replace
-no-virtio-balloon with

    -balloon none   disable balloon device
    -balloon virtio[,addr=str]
                    enable virtio balloon device (default)

This patch aligns the KVM-related layout and encoding of the CPU state
to be saved to disk or migrated with qemu-kvm. The major differences are
reordering of fields and a compressed interrupt_bitmap into a single
number as there can be no more than one pending IRQ at a time.

At this point, this refactoring looks like overkill. But we will need it
for CPU hotplugging, and qemu-kvm already carries it. Merging it early
would help qemu-kvm when rebasing against upstream.

During startup and after reset we have to synchronize user space to the
in-kernel KVM state. Namely, we need to transfer the VCPU registers when
they change due to VCPU as well as APIC reset.

This patch refactors the required hooks so that kvm_init_vcpu registers
its own per-VCPU reset handler and adds a cpu_synchronize_state to the
APIC reset. That way we no longer depend on the new reset order (and can
drop this disliked interface again) and we can even drop a KVM hook in
main().

The really time consuming part of snapshotting is to adjust the reference count
of all clusters. Currently after each adjusted cluster the refcount block is
written to disk.

Don't write each single byte immediately to disk but cache all writes to the
refcount block and write them out once we're done with the block.

When using O_DIRECT, qcow2 snapshots didn't work any more for me. In the
process of creating the snapshot, qcow2 tries to pwrite some new information
(e.g. new L1 table) which will often end up being after the old end of the
image file. Now pwrite tries to align things and reads the old contents of the
file, read returns 0 because there is nothing to read after the end of file and
pwrite is stuck in an endless loop.

This patch allows to pread beyond the end of an image file. Whenever the
given offset is after the end of the image file, the read succeeds and fills
the buffer with zeros.
