This adds CONFIG_IP_NF_TALK: talk support module for netfilter
connection tracking and NAT.  This allows both the callee client -
caller server and callee client - caller client connections to work
through connection tracking and NAT.

Default both talk (UDP port 517) and ntalk/ntalk2 (UDP port 518) are
supported. talk/ntalk/ntalk2 supports can selectively be enabled/disabled 
by the module parameters of the ip_conntrack_talk and ip_nat_talk
modules:

	talk=0|1
        ntalk=0|1
        ntalk2=0|1

where '0' means 'don't support' while '1' means 'do support'
the given protocol flavour.
