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.
