* ext/socket: Bypass getaddrinfo() if node and serv are numeric.

Browse source 
Reporeted by Naotoshi Seo.  [ruby-core:60801] [Bug #9525]

* ext/socket/extconf.rb: Detect struct sockaddr_in6.sin6_len.

* ext/socket/sockport.h (SET_SIN6_LEN): New macro.
  (INIT_SOCKADDR_IN6): Ditto.

* ext/socket/rubysocket.h (struct rb_addrinfo): Add
  allocated_by_malloc field.

* ext/socket/raddrinfo.c (numeric_getaddrinfo): New function.
  (rb_getaddrinfo): Call numeric_getaddrinfo at first.
  (rb_freeaddrinfo): Free struct addrinfo properly when it is
  allocated by numeric_getaddrinfo.
