[channels.c channels.h clientloop.c clientloop.h mux.c nchan.c ssh.c]
rewrite ssh(1) multiplexing code to a more sensible protocol.
The new multiplexing code uses channels for the listener and
accepted control sockets to make the mux master non-blocking, so
no stalls when processing messages from a slave.
avoid use of fatal() in mux master protocol parsing so an errant slave
process cannot take down a running master.
implement requesting of port-forwards over multiplexed sessions. Any
port forwards requested by the slave are added to those the master has
established.
add support for stdio forwarding ("ssh -W host:port ...") in mux slaves.
document master/slave mux protocol so that other tools can use it to
control a running ssh(1). Note: there are no guarantees that this
protocol won't be incompatibly changed (though it is versioned).

Implement a channel success/failure status confirmation callback
mechanism. Each channel maintains a queue of callbacks, which will
be drained in order (RFC4253 guarantees confirm messages are not
reordered within an channel).
Also includes a abandonment callback to clean up if a channel is
closed without sending confirmation messages. This probably
shouldn't happen in compliant implementations, but it could be
abused to leak memory.

try to keep channels open until an exit-status message is sent.
don't kill the login shells if the shells stdin/out/err is closed.
this should now work:
ssh -2n localhost 'exec > /dev/null 2>&1; sleep 10; exit 5'; echo ?

keep track of both maxfd and the size of the malloc'ed fdsets.
update maxfd if maxfd gets closed.

add support for RSA to SSH2. please test.
there are now 3 types of keys: RSA1 is used by ssh-1 only,
RSA and DSA are used by SSH2.
you can use 'ssh-keygen -t rsa -f ssh2_rsa_file' to generate RSA
keys for SSH2 and use the RSA keys for hostkeys or for user keys.
SSH2 RSA or DSA keys are added to .ssh/authorised_keys2 as before.
- (djm) Fix up Makefile and Redhat init script to create RSA host keys
- (djm) Change to interim version

cleanup copyright notices on all files. I have attempted to be
accurate with the details. everything is now under Tatu's licence
(which I copied from his readme), and/or the core-sdi bsd-ish thing
for deattack, or various openbsd developers under a 2-term bsd
licence. We're not changing any rules, just being accurate.
