New APIs for USB host support:

UsbManager:
- is now a service retrievable via Context.getSystemService(Context.USB_SERVICE).
- provides support for returning a list all connected USB devices
- broadcasts ACTION_USB_DEVICE_ATTACHED and USB_DEVICE_DETACHED when devices
  are added and removed from the USB host bus

UsbDevice:
- represents an attached USB device.

UsbInterface:
- represents an interface on a USB device
- devices may have multiple interfaces if they provide multiple
   sets of functionality (for example, android phones typically have interfaces
   for both USB mass storage and adb)

UsbEndpoint:
- represents an endpoint on a USB interface
- endpoints are used for sending or receiving data
  (only in one or the other direction)

UsbRequest:
- encapsulates a send or receive request to be sent over an endpoint
