reserve lower half of client lists for ipv4 for now

also rename client_in_list() to client_or_ip_port_in_list(), it also checks for an identical ip/port and replaces the client_id, recycling the entry

DHT.c:
- rename client_in_list() to client_or_ip_port_in_list()
- replace_bad(), replace_good(): if IPv6, only insert into the upper half of the given list
- addto_lists(): convert ipv4-in-ipv6 mapped to ipv4
