Current usblib tests only check receipt of a limited combination of 
packets lengths.

Added tests of receiving packets with invalid fields, and more complex
packet spanning. Also created tests for transmitting packets, covering
most code, except for mctp_usblib_tx_cancel() and allocation failures.
