Import of all remaining parts of the Poseidon port. This makes the source code delivery complete.
What's missing now is the final testing. I've experienced a crash in Trident in the depths of Zune,
but it does not happen if you use "AddUSBClasses" prior to starting Trident.
Help finding that one is appreciated.

This commit includes the following new components:
- asixeth.class
- usbaudio.class
- bluetooth.class
- camdusbmidi.class
- cdcacm.class
- dm9601eth.class
- dfu.class
- egalaxtouch.class
- ethwrap.class
- hid.class
- moschipeth.class
- palmpda.class
- pegasus.class
- printer.class
- ptp.class
- rawwrap.class
- serialcp210x.class
- serialpl2303.class
- simplemidi.class
- stir4200.class

There are now targets rom-usb (build everything) and rom-usb-classes (build all classes), too.
