Lots of extensions are completely family-independent, so squash some code.

Using ->family in struct xt_*_param, multiple struct xt_{match,target}

By passing in the family through which extensions were invoked, a bit
of data space can be reclaimed. The "family" member will be added to
the parameter structures and the check functions be adjusted.

This patch does this for match extensions' checkentry functions.

The function signatures for Xtables extensions have grown over time.
It involves a lot of typing/replication, and also a bit of stack space
even if they are not used. Realize an NFWS2008 idea and pack them into
structs. The skb remains outside of the struct so gcc can continue to
apply its optimizations.

This patch does this for match extensions' match functions.

A few ambiguities have also been addressed. The "offset" parameter for
example has been renamed to "fragoff" (there are so many different
offsets already) and "protoff" to "thoff" (there is more than just one
protocol here, so clarify).

Ebtables ORs (1 << NF_BR_NUMHOOKS) into the hook mask to indicate that
the extension was called from a base chain. So this also needs to be

The function signatures will be changed to match those of Xtables, and
the datalen argument will be gone. ebt_among unfortunately relies on
it, so we need to obtain it somehow.
