fix address size check
...
The rad pointer is an in_addr structure (IA), not a sockaddr structure
(SA), so make sure the memcmp call restricts itself to those many bytes.

support named ports with dashes in them
...
Normally netcat treats dashes as port ranges (e.g. "ssh-http"), but
there are port names with dashes in them (e.g. "ftp-data"). Allow
users to escape the dashes to support the latter mode.

change inet_addr to inet_aton
...
The former cannot differentiate between errors (-1) and 255.255.255.255.
Switch to inet_aton which does not have this problem.

Fix the size of a strncpy
...
It seems that the intent of this code was to only use the first char[24]
in `addrs` for this strncpy. While that should always happen anyway
(inet_ntoa should never produce a >= 24 char string), the mismatch
between the size of poop->addrs[0] and `sizeof(poop->addrs)` caused
issues with FORTIFY on clang.
