socks4a proxy support (like socks4 with remote DNS)

Fixes trac ticket 995 https://bugs.bitlbee.org/bitlbee/ticket/995

This is slightly pointless for the suggested use case (tor), since with
socks5 we already send a hostname instead of an IP address.

Either way, it was easy to implement, so I hope it helps.
