* fix secondary bus setup.
 * use base->name instead of "FIXME" for device name.
   Yes, the device name is redundant.  Only for drivers converted
   to qdev already though.  Once all drivers are converted we can
   and should kill it.

The only purpose DeviceType serves is creating a linked list of
DeviceInfo structs.  This removes DeviceType and add a next field to
DeviceInfo instead, so the DeviceInfo structs can be changed that way.
Elimitates a pointless extra level of indirection.

BusInfo is filled with name and size (pretty much like I did for
DeviceInfo as well).  There is also a function pointer to print
bus-specific device information to the monitor.  sysbus is hooked
up there, I've also added a print function for PCI.

Device creation is slightly modified as well:  The device type search
loop now also checks the bus type while scanning the list instead of
complaining thereafter in case of a mismatch.  This effectively gives
each bus a private namespace for device names.

Makes pci_qdev_register take a PCIDeviceInfo struct instead of a bunch
of parameters.  Also adds config_read and config_write callbacks to
PCIDeviceInfo, so drivers needing these can be converted to the qdev
device API too.

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)

Valgrind was so kind to remark that no one bothers to release keycodes
after use and that something is fishy about cleaning up the requested
keyboard descriptor. With this patch applied, we no longer leak about
12k during startup.

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.

Refactor the ACL monitor interface to make full use of the monitor
command dispatcher. This also gives proper help formatting and command
completion. Note that 'acl allow' and 'acl deny' were combined to
'acl_add aclname match allow|deny [index]' for consistency reasons.

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 "pci_addr=" prefix currently required by pci_add/remove and
drive_add has no practical use. Drop it, but still silently accept it
for backward compatibility.
