with bypass header, to send it out to userland.
- Use ng_ppp_bypass() in ng_ppp_proto_recv().
- Use ng_ppp_bypass() in ng_ppp_comp_recv() and in
ng_ppp_crypt_recv() if compression or encryption is
disabled, respectively.
- Any LCP packet goes directly to ng_ppp_bypass(), instead
of passing through PPP stack.
- Any non-LCP packet on disabled link is discarded. This
is behavior defined in RFC.

node would send every outgoing frame to the "compress" hook.
Packets received on the "compress" hook were expected to be
compressed and PROT_COMPD tag was put on them unconditionally.
After this commit an alternative compression mode can be set.
In this mode the node doesn't put the PROT_COMPD, the compressor
should put it itself. This is important for such kind of
compressors, that can submit uncompressed frames.
Before this commit, if the decompression is enabled, the ng_ppp(4)
node would send and incoming frame to the "decompress" hook
only if it has the PROT_COMPD proto tag on it.
After this commit an alternative decompression mode can be set.
In this mode the node sends all the incoming packets to the
decompression hook. This is important for such kind of compressors
that need uncompressed packets too, to keep their library in sync.
These new features will be used in new version of mpd4, and in new
compressor nodes.

This prevents repeated NGM_PPP_SET_CONFIG/NGM_PPP_GET_CONFIG

o Fix a bpf_compat issue where malloc() was defined to just call

to call bpf_alloc() but pass the corresponding M_TRYWAIT or M_DONTWAIT
flag (and only one of those two).

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 :-)

NGM_BINARY2ASCII, which convert control messages to ASCII and back.
This allows control messages to be sent and received in ASCII form
using ngctl(8), which makes ngctl a lot more useful.
This also allows all the type-specific debugging code in libnetgraph
to go away -- instead, we just ask the node itself to do the ASCII
translation for us.
Currently, all generic control messages are supported, as well as
messages associated with the following node types: async, cisco,
ksocket, and ppp.
See /usr/share/examples/netgraph/ngctl for an example of using this.
Also give ngctl(8) the ability to print out incoming data and
control messages at any time. Eventually nghook(8) may be subsumed.
Several other misc. bug fixes.
