Fix -4 option when IPv6 disabled
...
When IPv6 is disabled, hints_ai_family is set to AF_INET at initialization, resulting in the error "can't specify both -4 and -6" if the -4 option is supplied. If there's no IPv6, make the -4 option a no-op.

Update fping.c

Should only increase num_alive if response is not a duplicate.
In cases where multiple pings are sent, num_alive can increase past one for a host if a duplicate ping response is received while h->num_recv ==1.

Add backward compatibility for fping6 sym-link
Using sym-links to select IPv6 is discouraged (because it doesn't work the same for IPv4), but I understand that this can help for some use cases (i.e. in particular for the embedded linux distro use case, where having two binaries is an issue). Also, I guess nobody is going to have a binary called fping6 and expect it to do IPv4, so, I guess, no harm done.

Set the variable "prog" before the first call to any routine using error reporting
...
Error reporting uses the variable "prog" which is null prior to obtaining a
reference to argv[0]. The call to open_ping_socket() uses this on an error,
such as the executable not being SUID or otherwise privileged invocation.
Solaris 10 printf(3C) of "%s" on a null pointer causes a core dump.

Ignore network and broadcast for cidrs /31 and /32
...
fping has previously been strict about network address and broadcast
addreses. In the commit this is loosened a bit to permit fping to ping
cidrs with prefix length 31, which are commonly used for link ranges
(for newer equipment) and length 32 which denotes a single ip address.
For prefix lengths 31 and 32 fping will simply ignore network address
and broadcast addresses, and consider all addresses in range as a
target.
