Align netgraph message fields ready for 64-bit (and 128 bit :-) machines.

requires a recompile of netgraph users.
Also change the size of a field in the bluetooth code
that was waiting for the next change that needed recompiles so
it could piggyback its way in.

developers choose to disable these features on build machines
to maximize performance.

Netgraph changed its message format slightly to align the data
portion well on 64 bit machines.
Netgraph using utilities (e.g. ngctl, nghook, ppp, mpd,
pppoed, bluetooth, ATM) should be recompiled when a new kernel
is installed.

IPFW has been converted to use PFIL_HOOKS. This change is
transparent to userland and preserves the ipfw ABI. The ipfw
