gethostbynis.c:

- Fix problem described in PR #1079: _gethostbynisaddr() doesn't
  work. Make it accept the same arguments as all the other
  gethostby*addr() functions and properly convert the supplied IP
  address into a text string so that yp_match() can find it in the
  hosts.byaddr map.

- Also fix potential memory leak: copy the results of yp_match() to
  a static buffer and free the result (yp_match() returns dynamically
  allocated memory).

ether_addr.c:

- Since I was in the neighborhood, fix ether_ntohost() and
  ether_hostton() so that they don't bogusly for a free(result)
  when yp_match() fails.
