[tor-dev] [Patch] or/eventdns.c

I've made eventdns.c + '-DEVDNS_MAIN' compile and work under Windows / MSVC. Some simple patches:

* Use set_socket_nonblocking() instead of the F_SETFL hacks. * Preserve the ret-val from evdns_config_windows_nameservers(). * In main(), call network_init() to call WSAStartup() etc. * Removed 'evdns_resolv_conf_parse(DNS_OPTION_NAMESERVERS, ...' and call evdns_init() instead. This uses 'DNS_OPTIONS_ALL'. Does that really matter?

Attached diff-1.txt. (sorry, I'm a Git neophyte).
