[readconf.c readconf.h ssh.c ssh_config.5]
     reparse ssh_config and ~/.ssh/config if hostname canonicalisation changes
     the hostname. This allows users to write configurations that always
     refer to canonical hostnames, e.g.

     CanonicalizeHostname yes
     CanonicalDomains int.example.org example.org
     CanonicalizeFallbackLocal no

     Host *.int.example.org
         Compression off

[readconf.c ssh_config.5]
     rename "command" subclause of the recently-added "Match" keyword to
     "exec"; it's shorter, clearer in intent and we might want to add the
     ability to match against the command being executed at the remote end in
     the future.

[readconf.c readconf.h roaming_client.c ssh.1 ssh.c ssh_config.5]
     [sshconnect.c sshconnect.h]
     Implement client-side hostname canonicalisation to allow an explicit
     search path of domain suffixes to use to convert unqualified host names
     to fully-qualified ones for host key matching.
     This is particularly useful for host certificates, which would otherwise
     need to list unqualified names alongside fully-qualified ones (and this
     causes a number of problems).

[readconf.c readconf.h ssh_config.5 sshconnect.c]
     Add a ssh_config ProxyUseFDPass option that supports the use of
     ProxyCommands that establish a connection and then pass a connected
     file descriptor back to ssh(1). This allows the ProxyCommand to exit
     rather than have to shuffle data back and forth and enables ssh to use
     getpeername, etc. to obtain address information just like it does with
     regular directly-connected sockets. ok markus@

     Implement Elliptic Curve Cryptography modes for key exchange (ECDH) and
     host/user keys (ECDSA) as specified by RFC5656. ECDH and ECDSA offer
     better performance than plain DH and DSA at the same equivalent symmetric
     key length, as well as much shorter keys.

     Only the mandatory sections of RFC5656 are implemented, specifically the
     three REQUIRED curves nistp256, nistp384 and nistp521 and only ECDH and
     ECDSA. Point compression (optional in RFC5656 is NOT implemented).

     Certificate host and user keys using the new ECDSA key types are supported.

     Note that this code has not been tested for interoperability and may be
     subject to change.

[readconf.h readconf.c]
     Add client option UseRoaming. It doesn't do anything yet but will
     control whether the client tries to use roaming if enabled on the
     server. From Martin Forssen.

     [serverloop.c ssh-keyscan.c ssh.c sshd.c]
     make a2port() return -1 when it encounters an invalid port number
     rather than 0, which it will now treat as valid (needed for future work)
     adjust current consumers of a2port() to check its return value is <= 0,
     which in turn required some things to be converted from u_short => int
     make use of int vs. u_short consistent in some other places too
