Dag-Erling Smørgrav 8b55607a7f ping: Simplify protocol selection. 
* Interrupt the option loop as soon as we have an indication of which
  protocol is intended.
* If we end up having to perform a DNS lookup, loop over the entire
  result looking for either IPv4 or IPv6 addresses.

(cherry picked from commit 7fd2c91a29)

ping: Consistently use EX_NOHOST for DNS failures.

Traditionally, ping returned exit code EX_NOHOST if a DNS lookup failed.
That is still the case for the legacy code in the new merged ping, but
not for IPv6 targets, nor when a DNS lookup is performed in order to
determine which version of the tool to invoke.

While here, also make sure that the error message is consistent.
