for numeric addresses but for DNS lookup returned pointer to whole sockaddr_in or sockaddr_in6.
getaddrinfo() should be preferred in a long term perspective. Return of complete addresses from the lookup would be better in such case but it requires significant changes anyway - multiple addresses support and most probably dynamic memory allocation which is bad for many RT applications. So gethostbyname() is sufficient for most applications now.

- Rename include/nuttx/net/dnsclient.h to dns.h
- Move internal DNS prototypes from dns.h to libc/netdb/lib_dns.h
- Global standard DNS definitions from libc/netdb/dns_soccket.c to dns.h
- Eliminate dns_gethostip(). This is now an internal part of gethostbyname()
- Eliminate interface dns_whois(). Not needed in this new context.
