[PATCH 2.6 2/12]: add sysctl to read out the number of current

This patch adds a sysctl to read out the number of current connections.
ip_conntrack_count is an atomic_t, but it is read out by proc_dointvec.
I have checked all arches, all use an int, but I'm not sure if it works
on all of them.

[NETFILTER]: add sysctl to read out the number of current connections
Apparently a lot of scripts use a construct like
"cat /proc/net/ip_conntrack | wc -l"
which has a negative impact on system performance due to all the locking
