    libpayload: Add zero length packet support to UDC framework
    
    Some IN transfers must be terminated by an empty packet
    because otherwise the host wouldn't know.
    
    The zlp() function determines this requirement in
    accordance to USB rules: If the transfer's size is aligned
    to the maximum packet size, and the host expects a larger
    transfer, add the empty packet as a hint.
    
    BRANCH=none
    BUG=none
    TEST=USB device mode still works
