print potentially sensitive keying material to stdout. With the new
802.11 support, ifconfig(8) is now capable of printing 802.11 keys,
and did by default for the root user, which is undesirable in some
environments. Now it will not print keying material unless requested
(and available to the user).

If a write(2) on devd.pipe would block, the client in question will be

Change communication protocol to be much more resistant on network
problems and to allow for much better performance.
Better performance is achieved by creating two connections between
ggatec and ggated one for sending the data and one for receiving it.
Every connection is handled by separeted thread, so there is no more
synchronous data flow (send and wait for response), now one threads
sends all requests and another receives the data.
Use two threads in ggatec(8):
- sendtd, which takes I/O requests from the kernel and sends them to the
ggated daemon on the other end;
- recvtd, which waits for ggated responses and forwards them to the kernel.
Use three threads in ggated(8):
- recvtd, which waits for I/O requests and puts them onto incoming queue;
- disktd, which takes requests from the incoming queue, does disk operations
and puts finished requests onto outgoing queue;
- sendtd, which takes finished requests from the outgoing queue and sends
responses back to ggatec.
Because there were major changes in communication protocol, there is no
backward compatibility, from now on, both client and server has to run
on 5.x or 6.x (or at least ggated should be from the same FreeBSD version
on which ggatec is running).
For Gbit networks some buffers need to be increased. I use those settings:
kern.ipc.maxsockbuf=16777216
net.inet.tcp.sendspace=8388608
net.inet.tcp.recvspace=8388608
and I use '-S 4194304 -R 4194304' options for both, ggatec and ggated.

include a space seperated list of domains instead of the domain of the
host. This is supported on too many platforms to break for now so,
remove validation of this option for the moment.
The correct solution longer term is to implement RFC 3397 support and
then treat domain-name options containing space seperated lists of
domains as domain-search options for backwards compatability.

Add a -b option to background immediatly.
Add support for 802.11 routing messages to "instantly" renegotiate
at lease when we associate with a new network.
