usb-audio is a full speed (1.1) device,
but bcdUSB claims it is usb 2.0. Fix it.

This patch adds a function which creates unique serial numbers for usb
devices and puts it into use. Windows guests tend to become unhappy if
they find two identical usb devices in the system. Effects range from
non-functional devices (with yellow exclamation mark in device manager)
to BSODs. Handing out unique serial numbers to devices fixes this.
With this patch applied almost all emulated devices get a generated,
unique serial number. There are two exceptions:
* usb-storage devices will prefer a user-specified serial number
and will only get a generated number in case the serial property
is unset.
* usb-hid devices keep the fixed serial number "42" as it is used
to signal "remote wakeup actually works".

Reorganize usb source files. Create a new hw/usb/ directory and move
all usb source code to that place. Also make filenames a bit more
descriptive. Host adapters are prefixed with "hch-" now, usb device
emulations are prefixed with "dev-". Fixup paths Makefile and include
paths to make it compile. No code changes.
