This patch adds support to auto-generate BSF code for IPv6. It
requires a Linux kernel >= 2.6.29. The maximum number of addresses
is limited to 20 (12 BSF lines per IPv6 address comparison). I am
not sure that to remove this limit is useful given that oprofile
does not show very good numbers for very large (in terms of lines)
filters. This completes one feature that is available in IPv4 but
that was missing in IPv6.

This patch reworks the BSF automatic generation code. This
feature needs more love and it has several limitations like
that the maximum number of IPs are 127 due to BSF code
restrictions. See this patch as a first step forward.
This patch also adds the stack data type, which is used to
resolve jump dynamically instead of the previous static
approach.
This patch also includes fixes in the limitations, previous
calculations were wrong.

This patch adds the size of the arrays to set to NULL unset
elements. This helps to spot unset functions for new attributes.

This patch adds an abstraction level to berkeley sockets filter (BSF) for
Netlink sockets available since Linux kernel 2.6.26. This provides an
easy way to attach filters without knowing about BSF at all.
