I don't think it's critical to do this, but it's
best to keep uninit and error recovery consistent.

This patch addresses the problems found by Andriy Gapon:
- The code was incorrectly overwriting the high order 32
bits of the timer and hpet config registers. This didn't show up
in testing because linux and windows use hpet in legacy mode,
where the high order 32 bits (advertising available interrupts)
of the timer config register are ignored, and the high order 32
bits of the hpet config register are reserved and unused.
- The mask for level-triggered interrupts was off by a bit. (hpet
doesn't currently support level-triggered interrupts).
In addition, I removed some unused #defines, and corrected the ioapic
interrupt values advertised. I'd set this up early in hpet development
and never went back to correct it, and no bugs resulted since linux and
windows use hpet in legacy mode where available interrupts are ignored.

Implementing a alternative way to specify the filename should be

should look like.

cleanup pretty simliar to the drives_table removal patch:
- drop the table and make a linked list out of it.
- pass around struct pointers instead of table indices.

First step cleaning up the drives handling. This one does nothing but
removing drives_table[], still it became seriously big.
drive_get_index() is gone and is replaced by drives_get() which hands
out DriveInfo pointers instead of a table index. This needs adaption in
*tons* of places all over.
The drives are now maintained as linked list.

This patch implements a parser and qdev tree walker for bus paths and
adds qdev_device_add on top of this.
A bus path can be:
(1) full path, i.e. /i440FX-pcihost/pci.0/lsi/scsi.0
(2) bus name, i.e. "scsi.0". Best used together with id= to make
sure this is unique.
(3) relative path starting with a bus name, i.e. "pci.0/lsi/scsi.0"
For the (common) case of a single child bus being attached to a device
it is enougth to specify the device only, i.e. "pci.0/lsi" will be
accepted too.
qdev_device_add() adds devices and accepts bus= parameters to find the
bus the device should be attached to. Without bus= being specified it
takes the first bus it finds where the device can be attached to (i.e.
first pci bus for pci devices, ...).

Create a default bus name if none is passed to qbus_create().
If the parent device has DeviceState->id set it will be used to create
the bus name,. i.e. -device lsi,id=foo will give you a scsi bus named
"foo.0".
If there is no id BusInfo->name (lowercased) will be used instead, i.e.
-device lsi will give you a scsi bus named "scsi.0".
A scsi adapter with two scsi busses would have "scsi.0" and "scsi.1" or
"$id.0" and "$id.1" busses. The numbers of the child busses are per
device, i.e. when adding two lsi adapters both will have a "*.0" child
bus.

The pc-0.11 type allows users of qemu-0.11 to use a machine type which
they know will remain compatible when the upgrade to qemu-0.12.
Management tools may choose to canonicalize the 'pc' machine type to
'pc-0.11' so that if the 'pc' alias changes target in future versions
of qemu, the machine type used will remain compatible.

Add an 'alias' field to QEMUMachine and display it in the output of
'qemu -M ?' with an '(aliased to foo)' suffix.
Aliases can change targets in newer versions of qemu, so management tools
may choose canonicalize machine types to ensure that if a user chooses an
alias, that the actual machine type used will remain compatible in
future.
This is intended to mimic a symlink to a machine description file.

When giving KVM a slot of a size not on page boundary, it chokes. So let's
