- Add C-bus and ISA front-ends for le(4) so it can actually replace

Browse source 
lnc(4) on PC98 and i386. The ISA front-end supports the same non-PNP
  network cards as lnc(4) did and additionally a couple of PNP ones.
  Like lnc(4), the C-bus front-end of le(4) only supports C-NET(98)S
  and is untested due to lack of such hardware, but given that's it's
  based on the respective lnc(4) and not too different from the ISA
  front-end it should be highly likely to work.
- Remove the descriptions of le(4), which where converted from lnc(4),
  from sys/i386/conf/NOTES and sys/pc98/conf/NOTES as there's a common
  one in sys/conf/NOTES.
