This clears out my outstanding netgraph changes.
There is a netgraph change of design in the offing and this is to some
extent a superset of soem of the new functionality and some of the old
functionality that may be removed.

This code works as before, but allows some new features that I want to
work with and evaluate. It is the basis for a version of netgraph
with integral locking for SMP use.

This is running on my test machine with no new problems :-)

db0edd3c39 Fix a bug where if the interface was in promiscuous mode when the 
last hook was disconnected, the interface would not get reset to
non-promiscuous mode.

5d83d171df Go back to using data_len in struct ngpppoe_init_data after discussions 
with Julian and Archie.

Implement a new ``sizedstring'' parse type for dealing with field pairs
consisting of a uint16_t followed by a data field of that size, and use
this to deal with the data_len and data fields.

27f10d8332 Swap the order of two tags in the pppoe PADI and PADS packets

87f7d0a784 Change the format of ngpppoe_init_data so that the provider is NUL 
terminated and the data_len field is no longer necessary.

Add ASCII2BINARY and BINARY2ASCII capabilities.

The old format is still understood and dealt with, but can't do
the ASCII2BINARY and BINARY2ASCII stuff.

ff5cdfae2d Move suser() and suser_xxx() prototypes and a related #define from 
<sys/proc.h> to <sys/systm.h>.

Correctly document the #includes needed in the manpage.

Remove the consequent 48 unused #includes of <sys/proc.h>.

7280bb2b3d Use m_dup() instead of m_copypacket() for the time being. Not all 
of the code in the kernel properly checks for read-onlyness before
writing into an mbuf data area. When that code is fixed, the m_dup()
can go back to being m_copypacket().

769e0f974d Major update to the way synchronization is done in the kernel. Highlights 
include:

* Mutual exclusion is used instead of spl*().  See mutex(9).  (Note: The
  alpha port is still in transition and currently uses both.)

* Per-CPU idle processes.

* Interrupts are run in their own separate kernel threads and can be
  preempted (i386 only).

36af4d0d2a RFC 1661 requires that all LCP packets are sent with no address and 
control field compression. The ng_ppp(4) node correctly follows this
rule. However, PPPoE is an exception: when doing PPPoE *all* frames
are sent with address and control field compression.

Alter this node's behavior so that when an outgoing frame is received,
any leading address and control field bytes are removed. This makes
this node compatible with ng_ppp(4).
