As reported on IRC by deese, asking the relay plugin to bind to a specific IP address will cause strange errors...

20:00 (deese) any clue about this error? 19:01 weechat     =!= relay: cannot "bind" on port 9001 (ipv4.ssl.weechat): error 97 Address family not supported by protocol

...since it gives a garbage address to bind():

20:04 (deese) socket(PF_INET, SOCK_STREAM, IPPROTO_IP) = 37
20:04 (deese) bind(37, {sa_family=0x20b2 /* AF_??? */, sa_data="6260262 6260��������"}, 16) = -1 EAFNOSUPPORT (Address family not supported by protocol)

The problem is caused by an inet_pton() call in relay_server_create_socket() overwriting the beginning of *ptr_addr, where the sa_family and sa_port fields reside.

Patch attached.
