First user of the new drive property. With this patch applied host
and guest config can be specified separately, like this:
-drive if=none,id=disk1,file=/path/to/disk.img
-device virtio-blk-pci,drive=disk1
You can set any property for virtio-blk-pci now. You can set the pci
address via addr=. You can switch the device into 0.10 compat mode
using class=0x0180. As this is per device you can have one 0.10 and one
0.11 virtio block device in a single virtual machine.
Old syntax continues to work. Internally it does the same as the two
lines above though. One side effect this has is a different
initialization order, which might result in a different pci address
being assigned by default.
Long term plan here is to have this working for all block devices, i.e.
once all scsi is properly qdev-ified you will be able to do something
like this:
-drive if=none,id=sda,file=/path/to/disk.img
-device lsi,id=lsi,addr=<pciaddr>
-device scsi-disk,drive=sda,bus=lsi.0,lun=<n>

Once again, the emulation of the EERD and ICS registers in e1000.c is
incorrect. Nobody has noticed this before because none of the Intel-written
e1000 drivers use these registers, and all of the independently written open
source drivers copy Intel's example, so they don't use them either.
Regardless, these registers are documented in the programmer's manuals, and
their emulated behavior doesn't match the verified behavior of real hardware,
so any software that does use them doesn't function correctly.

When a VM state change handler changes VM state, other VM state change
handlers can see the state transitions out of order.
bmdma_map(), scsi_disk_init() and virtio_blk_init() install VM state
change handlers to restart DMA. These handlers can vm_stop() by
running into a write error on a drive with werror=stop. This throws
the VM state change handler callback into disarray. Here's an example
case I observed:
0. The virtual IDE drive goes south. All future writes return errors.
1. Something encounters a write error, and duly stops the VM with
vm_stop().
2. vm_stop() calls vm_state_notify(0).
3. vm_state_notify() runs the callbacks in list vm_change_state_head.
It contains ide_dma_restart_cb() installed by bmdma_map(). It also
contains audio_vm_change_state_handler() installed by audio_init().
4. audio_vm_change_state_handler() stops audio stuff.
5. User continues VM with monitor command "c". This runs vm_start().
6. vm_start() calls vm_state_notify(1).
7. vm_state_notify() runs the callbacks in vm_change_state_head.
8. ide_dma_restart_cb() happens to come first. It does its work, runs
into a write error, and duly stops the VM with vm_stop().
9. vm_stop() runs vm_state_notify(0).
10. vm_state_notify() runs the callbacks in vm_change_state_head.
11. audio_vm_change_state_handler() stops audio stuff. Which isn't
running.
12. vm_stop() finishes, ide_dma_restart_cb() finishes, step 7's
vm_state_notify() resumes running handlers.
13. audio_vm_change_state_handler() starts audio stuff. Oopsie.
Fix this by moving the actual write from each VM state change handler
into a new bottom half (suggested by Gleb Natapov).

These are now unused.
However, perhaps the idea is that when we add -device, they will be
useful? In that case, we should add virtio-net-pci-0-10 too.

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.

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.
