libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac and

Add variable to force binding of nfnetlink_log.
This patch updates the behaviour of the NFLOG input plugin to fix an
issue related to kernel older than 2.6.29. The call to nflog_bind_pf()
that can be necessary to receive packet from the nfnetlink_log was only
done if the used group was 0 (system logging). This is logic for the
newest kernel (NFLOG really sends message to nfnetlink_log and not to
the nf_log logger). But this is unsufficient for older one. By forcing
the binding with the new configuration variable bind, it is now possible
to trigger the binding from the ulogd2 configuration file. This gives
users a way to be sure that ulogd will receive packets if the NFLOG
input plugin is used.

Get rid of addressfamily variable in NFLOG input plugin
The addressfamily configuration variable for NFLOG is used as param
for nflog_bind_pf. This function is used to claim the fetching of
kernel message sent via nf_log_packet() function.
As all kernel messages are sent to the group 0, it is useless to
call nflog_bind_pf when nflog group of the input plugin is not 0.
Furthermore, as only one plugin can be bound to nflog group 0, it
is mandatory to call nflog_bind_pf for all pf family when the group
is 0.
To sum up, this patch suppress the adressfamily parameter (which
simplify the configuration file) and call nflog_bind_pf for all
pf family when the nflog group of the instance is 0.

Modify usage of nflog_bind_pf function.
The nflog_bind_pf function was called for each NFLOG instance. This patch
modifies the behaviour to have it call if and only if the nfgroup is set
to 0. As the kernel uses only the 0 group to output subsystem messages,
this change clarify the situation.
This patch cleans up the current key assignation by introducing a
set of functions ukey_* to set the key value as Eric Leblond and
