usb: Move (initial) call of usb_port_location to usb_fill_port
Cleanup / preparation patch for companion controller support. Note thatas a "side-effect" this patch also fixes the milkymist-softusb controllernot having a port_location set for its ports....
usb: Add a register_companion USB bus op.
This is a preparation patch for adding support for USB companion controllers.

usb: Replace device_destroy bus op with a child_detach port op
Note this fixes 2 things in one go, first of all the device_destroy busop should be a device_detach bus op, as pending async packets from thedevice should be cancelled on detach not on destroy....
usb: Add a usb_fill_port helper function
usb-bus: Don't allow speed mismatch while attaching devices

usb-bus: Don't allow attaching a device to a bus with no free ports
usb: Proper error propagation for usb_device_attach errors
usb: cancel async packets on unplug
This patch adds USBBusOps struct with (for now) only a single callbackwhich is called when a device is about to be destroyed. The USB Hostadapters are implementing this callback and use it to cancel any asyncrequests which might be in flight before the device actually goes away....
usb-bus: Add knowledge of USB_SPEED_SUPER to usb_speed helper
usb-bus: Don't detach non attached devices on device exit
This causes an "Error: tried to detach unattached usb device " to be printed,this can happen when deleting ie a usb host qdev, which did notget attached (because a device matching the filter never got plugged in)....
usb-bus: use snprintf
Avoid this warning from OpenBSD linker: LINK i386-softmmu/qemu../usb-bus.o(.text+0x27c): In function `usb_get_fw_dev_path':/src/qemu/hw/usb-bus.c:294: warning: sprintf() is often misused,please use snprintf()

usb core: add migration support
Yes, seriously. There is no migration support at all for usb devices.They loose state, especially the device address, and stop respondingbecause of that. Oops.
Luckily there is so much broken usb hardware out there that the guest...
usb: zap pdev from usbport
It isn't needed any more.
usb: rewrite fw path, fix numbering
This patch rewrites the firmware path code to use the physical portlocation tracking just added to the qemu usb core. It also fixes theport numbering to start with "1" in the firmware path.
usb: add port property.
This allows to explictily set the physical port where you want toplug the usb device. Example:
-device usb-tablet,bus=usb.0,port=2
With explicit port addressing qemu can and will not automagically addUSB Hubs. This means that:...
usb: keep track of physical port address.
Add a path string to USBPort. Add usb_port_location() function to setthe physical location of the usb port. Update all drivers implementingusb ports to call it. Update the monitor commands to print it. Wind it...
usb: add speed mask to ports
Add a field to usb ports indicating the speed(s) they areable to handle.
usb: create USBPortOps, move attach there.
Create USBPortOps struct, move the attach function to that struct.
usb descriptors: add settable strings.
This patch allows to set usb descriptor strings per device instance.
Record which USBDevice USBPort belongs too.
Ports on root hub will have NULL here. This is needed to reconstructpath from device to its root hub to build device path.

usb-bus: fix no params
After commit 702f3e0fb52c124c07f215426eeadb70a716643f, the params isnerver NULL. It should check *params instead of params to determinewhether the params is empty.

error: Replace qemu_error() by error_report()
error_report() terminates the message with a newline. Strip it itfrom its arguments.
This fixes a few error messages lacking a newline:net_handle_fd_param()'s "No file descriptor named %s found", andtap_open()'s "vnet_hdr=1 requested, but no kernel support for...
Fix -usbdevice crash
If -usbdevice is used on a machine with no USB busses, usb_createwill fail and return NULL. Patch below handles this failure gracefullyrather than crashing when we try to init the device.

usb core: use qdev for -usbdevice
