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

	otalk=0|1
	talk=0|1

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

This patch depends on the dropped-table patch.
