qemu-doc: Update to use the new way of attaching USB devices
The preferred way of adding USB devices is via "-device" and "device_add" nowadays, so let's start to get rid of "-usbdevice" and "usb_add" in the documentation. While we're at it, also add the new USB devices there which have been added to QEMU during the last years, and get rid of the old "vendorid" and "productid" parameters of "-usbdevice serial" which have been removed in QEMU version 0.14.0 already.

device @var{dev}. The available character devices are the same as for the
|

@code{-serial} option. The @code{vendorid} and @code{productid} options can be

Network adapter that supports CDC ethernet and RNDIS protocols. @var{id}

Bluetooth dongle for the transport layer of HCI. It is connected to HCI

|

Note that the syntax for the @code{-device usb-bt-dongle} option is not as

configure an USB bluetooth device, you might need to use

"@code{-usbdevice bt}[:@var{hci-type}]" instead. This configures a

bluetooth dongle whose type is specified in the same format as with

the @option{-bt hci} option, @pxref{bt-hcis,,allowed HCI types}. If
|

no type is given, the HCI logic corresponds to @code{-bt hci,vlan=0}.
