netfilter 00/03: netfilter -stable fixes

[Patrick McHardy <kaber@trash.net>]

The following three patches for -stable fix a number of netfilter
regressions:

- revision lookup for x_tables matches and targets registering with
  the new NFPROTO_UNSPEC is broken, causing failures when using
  features not offered by revision 0. New regression in 2.6.28.

- ebtables interprets return values from matches in the inverted
  sense. New regression in 2.6.28.

- the conntrack timeout sysctls for ICMP/ICMPv6 are broken on big
  endian due to a mismatch between the data type size and the size
  registered with the sysctls. Seems to be a regression from the
  switch from ip_conntrack to nf_conntrack.

Please apply, thanks.
