replace our obsolete smartcard code with PKCS#11.
ftp://ftp.rsasecurity.com/pub/pkcs/pkcs-11/v2-20/pkcs-11v2-20.pdf
ssh(1) and ssh-keygen(1) use dlopen(3) directly to talk to a PKCS#11
provider (shared library) while ssh-agent(1) delegates PKCS#11 to
a forked a ssh-pkcs11-helper process.
PKCS#11 is currently a compile time option.

report by imorgan AT nas.nasa.gov
[clientloop.c]
downgrade an error() to a debug() - this particular case can be hit in
normal operation for certain sequences of mux slave vs session closure
and is harmless
after registering the hardware engines, which causes the openssl.cnf file to
be processed. See OpenSSL's man page for OPENSSL_config(3) for details.
Patch from Solomon Peachy, ok djm@.
[mux.c]
fix bug introduced in mux rewrite:
In a mux master, when a socket to a mux slave closes before its server
session (as may occur when the slave has been signalled), gracefully
close the server session rather than deleting its channel immediately.
A server may have more messages on that channel to send (e.g. an exit
message) that will fatal() the client if they are sent to a channel that
has been prematurely deleted.
spotted by imorgan AT nas.nasa.gov
[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).

Remove RoutingDomain from ssh since it's now not needed. It can be
replaced with "route exec" or "nc -V" as a proxycommand. "route exec"
also ensures that trafic such as DNS lookups stays withing the specified
routingdomain. For example (from reyk):
# route -T 2 exec /usr/sbin/sshd
or inherited from the parent process
$ route -T 2 exec sh
$ ssh 10.1.2.3

Implement tab-completion of commands, local and remote filenames for sftp.
Hacked on and off for some time by myself, mouring, Carlos Silva (via 2009
Google Summer of Code) and polished to a fine sheen by myself again.
It should deal more-or-less correctly with the ikky corner-cases presented
by quoted filenames, but the UI could still be slightly improved.
In particular, it is quite slow for remote completion on large directories.

When passing user-controlled options with arguments to other programs,
pass the option and option argument as separate argv entries and
not smashed into one (e.g., as -l foo and not -lfoo). Also, always
pass a "--" argument to stop option parsing, so that a positional
argument that starts with a '-' isn't treated as an option. This
fixes some error cases as well as the handling of hostnames and
filenames that start with a '-'.
