Unfortunately in-kernel 64bit counters are still required, for example for "connbytes" extension. However, 64bit counters waste a lot of memory and it was not possible to enable/disable it runtime. This patch: - reimplements accounting with respect to the extension infrastructure, - makes one global version of seq_print_acct() instead of two seq_print_counters(), - makes it possible to enable it at boot time (for CONFIG_SYSCTL/CONFIG_SYSFS=n), - makes it possible to enable/disable it at runtime by sysctl or sysfs, - extends counters from 32bit to 64bit, - renames ip_conntrack_counter -> nf_conn_counter, - enables accounting code unconditionally (no longer depends on CONFIG_NF_CT_ACCT), - set initial accounting enable state based on CONFIG_NF_CT_ACCT - removes buggy IPCT_COUNTER_FILLING event handling. If accounting is enabled newly created connections get additional acct extend. Old connections are not changed as it is not possible to add a ct_extend area to confirmed conntrack. Accounting is performed for all connections with acct extend regardless of a current state of "net.netfilter.nf_conntrack_acct".
