qdev: add return value to init() callbacks.
Sorry folks, but it has to be. One more of these invasive qdev patches.
We have a serious design bug in the qdev interface: device initcallbacks can't signal failure because the init() callback has noreturn value. This patch fixes it....
fix qdev_print_devinfo()
snprintf returns number of bytes needed for the output, not the numberof bytes actually written. Thus the math is wrong ...

rename "info qdrv" to "info qdm"
As requested by avi: driver != device model.

QemuOpts: switch over -device.
Make -device switch use the QemuOpts framework.Everything should continue to work like it did before.
New: "-set device.$id.$property=$value" works.
tolower -> qemu_tolower
Use qemu_tolower() instead of tolower().Fixes warning on NetBSD.

kill drives_table
First step cleaning up the drives handling. This one does nothing butremoving drives_table[], still it became seriously big.
drive_get_index() is gone and is replaced by drives_get() which handsout DriveInfo pointers instead of a table index. This needs adaption in...
qdev: create default bus names.
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 createthe 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....
qdev: bus walker + qdev_device_add()
This patch implements a parser and qdev tree walker for bus paths andadds 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...
Suppress a Sparse warning
Move the export to a file used by both qdev.c and sysbus.c.

qdev: add user-specified identifier to devices.
Add id field to DeviceState. Make "info qtree" print it.
This helps users and management apps identifying devices in monitoroutput, which is especially useful with otherwise identical devicessuch as two virtio disks....
qdev: factor out driver search to qdev_find_info()
qdev/compat: compat property infrastructure.
This add support for switching devices into a compatibility modeusing device properties. Machine types can have a list of propertiesfor specific devices attached to allow the easy creation of machinetypes compatible to older qemu versions....
qdev: add no_user, alias and desc
no_user: prevent users from adding certain devices.desc: description of the device.alias: to allow user friendly shortcuts on the command line, i.e. -device usbmouse instead of -device "QEMU USB Mouse" or -device lsi instead of -device lsi53c895a...
qdev: rework device properties.
This patch is a major overhaul of the device properties. The propertiesare saved directly in the device state struct now, the linked list ofproperty values is gone.
Advantages: * We don't have to maintain the list with the property values....
Update to a hopefully more future proof FSF address
Don't leak VLANClientState on PCI hot remove
destroy_nic() requires that NICInfo::private by a PCIDevice pointer,but then goes on to require that the same pointer matchesVLANClientState::opaque.
That is no longer the case for virtio-net since qdev and wasn't...
qdev: replace bus_type enum with bus_info struct.
BusInfo is filled with name and size (pretty much like I did forDeviceInfo as well). There is also a function pointer to printbus-specific device information to the monitor. sysbus is hookedup there, I've also added a print function for PCI....
qdev: remove DeviceType
The only purpose DeviceType serves is creating a linked list ofDeviceInfo structs. This removes DeviceType and add a next field toDeviceInfo instead, so the DeviceInfo structs can be changed that way.Elimitates a pointless extra level of indirection....
qdev: move name+size into DeviceInfo (v2)
Rationale: move device information from code to data structures.
v2: Adapt the drivers missed in the first version.

net: add fd_readv() handler to qemu_new_vlan_client() args
This, apparently, is the style we prefer - all VLANClientStateshould be an argument to qemu_new_vlan_client().

net: re-name vc->fd_read() to vc->receive()
VLANClientState's fd_read() handler doesn't read from filedescriptors, it adds a buffer to the client's receive queue.
Re-name the handlers to make things a little less confusing.

Remove qdev irq sink handling
We have both IRQ sinks and GPIO inputs. These are in principle exactlythe same thing, so remove the former.
Add common BusState
Implement and use a common device bus state. The main side-effect isthat creating a bus and attaching it to a parent device are no longerseparate operations. For legacy code we allow a NULL parent, but thatshould go away eventually....
