Added NE2000 Driver from Ian Lance Taylor <ian@airs.com>. Comments:

    Both the ne2000 and the wd80x3 are based on the National Semiconductor
    8390 chip, so there is a fair amount of overlap between the two
    drivers.  It would be possible in principle to combine some code into
    a separate set of subroutines called by both.  In fact, the drivers in
    both OpenBSD and Linux work this way.  I didn't bother, because for
    the relatively simple drivers used by RTEMS, the overlap is not
    especially large, and any reasonable use of subroutines would lead to
    slightly less efficient code.

    This ne2000 driver uses two transmit buffers.  While one packet is
    being transmitted over the Ethernet, RTEMS will upload another.  Since
    uploading a packet to the ne2000 is rather slow, I don't think there
    is any point to having more than two transmit buffers.  However, the
    code does make it possible, by changing NE_TX_BUFS, although that
    would of course reduce the number of receive buffers.

    I suspect that the wd80x3 driver would benefit slightly from copying
    the multiple transmit buffer code.  However, I have no way to test
    that.
