Added new USB_Host_ClearPipeStall() convenience function to clear a stall condition on an attached device's endpoint.

Added new USB_Host_GetDeviceDescriptor() convenience function to retrieve the attached device's Device descriptor.

Make Pipe_ConfigurePipe() mask the given endpoint number against PIPE_EPNUM_MASK to ensure the endpoint IN direction bit is cleared to prevent endpoint type corruption.

Fix documentation mentioning Pipe_GetCurrentToken() function when real name is Pipe_GetPipeToken().
