avoid spinning when fd passing on nonblocking sockets by calling poll()
in the EINTR/EAGAIN path, much like we do in atomicio; ok dtucker@

Do not prompt for a passphrase if we fail to open a keyfile, and log the
reason the open failed to debug.

[ssh_config channels.c ssh.1 channels.h ssh.c]
Add a 'netcat mode' (ssh -W). This connects stdio on the client to a
single port forward on the server. This allows, for example, using ssh as
a ProxyCommand to route connections via intermediate servers.

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

[sshd.c]
Afer sshd receives a SIGHUP, ignore subsequent HUPs while sshd re-execs
itself. Prevents two HUPs in quick succession from resulting in sshd
dying. bz#1692, patch from Colin Watson via Ubuntu.

Prevent sftp from derefing a null pointer when given a "-" without a
command. Also, allow whitespace to follow a "-". bz#1691, path from
Colin Watson via Debian. ok djm@ deraadt@

quell tc[gs]etattr warnings when forcing a tty (ssh -tt), since we

[sftp-server.c sftp-server.8]
add a 'read-only' mode to sftp-server(8) that disables open in write mode
and all other fs-modifying protocol methods. bz#430 ok dtucker@
[sftp.c]
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.

Rename RDomain config option to RoutingDomain to be more clear and
consistent with other options.
NOTE: if you currently use RDomain in the ssh client or server config,
or ssh/sshd -o, you must update to use RoutingDomain.

[ssh.c sftp.c scp.c]
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 '-'.

[sftp.c]
fix potential divide-by-zero in sftp's "df" output when talking to a server
that reports zero files on the filesystem (Unix filesystems always have at
least the root inode). From Steve McClellan at radisys, ok djm@

correct off-by-one in percent_expand(): we would fatal() when trying
to expand EXPAND_MAX_KEYS, allowing only EXPAND_MAX_KEYS-1 to actually
work. Note that nothing in OpenSSH actually uses close to this limit at
present. bz#1607 from Jan.Pechanec AT Sun.COM
