Merge 6.7p1.

  * New upstream release (http://www.openssh.com/txt/release-6.7):
    - sshd(8): The default set of ciphers and MACs has been altered to
      remove unsafe algorithms.  In particular, CBC ciphers and arcfour* are
      disabled by default.  The full set of algorithms remains available if
      configured explicitly via the Ciphers and MACs sshd_config options.
    - ssh(1), sshd(8): Add support for Unix domain socket forwarding.  A
      remote TCP port may be forwarded to a local Unix domain socket and
      vice versa or both ends may be a Unix domain socket (closes: #236718).
    - ssh(1), ssh-keygen(1): Add support for SSHFP DNS records for ED25519
      key types.
    - sftp(1): Allow resumption of interrupted uploads.
    - ssh(1): When rekeying, skip file/DNS lookups of the hostkey if it is
      the same as the one sent during initial key exchange.
    - sshd(8): Allow explicit ::1 and 127.0.0.1 forwarding bind addresses
      when GatewayPorts=no; allows client to choose address family.
    - sshd(8): Add a sshd_config PermitUserRC option to control whether
      ~/.ssh/rc is executed, mirroring the no-user-rc authorized_keys
      option.
    - ssh(1): Add a %C escape sequence for LocalCommand and ControlPath that
      expands to a unique identifer based on a hash of the tuple of (local
      host, remote user, hostname, port).  Helps avoid exceeding miserly
      pathname limits for Unix domain sockets in multiplexing control paths.
    - sshd(8): Make the "Too many authentication failures" message include
      the user, source address, port and protocol in a format similar to the
      authentication success / failure messages.
    - Use CLOCK_BOOTTIME in preference to CLOCK_MONOTONIC when it is
      available. It considers time spent suspended, thereby ensuring
      timeouts (e.g. for expiring agent keys) fire correctly (closes:
      #734553).
    - Use prctl() to prevent sftp-server from accessing
      /proc/self/{mem,maps}.
  * Restore TCP wrappers support, removed upstream in 6.7.  It is true that
    dropping this reduces preauth attack surface in sshd.  On the other
    hand, this support seems to be quite widely used, and abruptly dropping
    it (from the perspective of users who don't read openssh-unix-dev) could
    easily cause more serious problems in practice.  It's not entirely clear
    what the right long-term answer for Debian is, but it at least probably
    doesn't involve dropping this feature shortly before a freeze.
  * Replace patch to disable OpenSSL version check with an updated version
    of Kurt Roeckx's patch from #732940 to just avoid checking the status
    field.

+2.4. connection: Unix domain socket forwarding
+
+OpenSSH supports local and remote Unix domain socket forwarding
+using the "streamlocal" extension.  Forwarding is initiated as per
+TCP sockets but with a single path instead of a host and port.
+
+Similar to direct-tcpip, direct-streamlocal is sent by the client
+to request that the server make a connection to a Unix domain socket.
+
+        byte            SSH_MSG_CHANNEL_OPEN
+        string          "direct-streamlocal@openssh.com"
+        uint32          sender channel
+        uint32          initial window size
+        uint32          maximum packet size
+        string          socket path
+        string          reserved for future use
+
+Similar to forwarded-tcpip, forwarded-streamlocal is sent by the
+server when the client has previously send the server a streamlocal-forward
+GLOBAL_REQUEST.
+
+        byte            SSH_MSG_CHANNEL_OPEN
+        string          "forwarded-streamlocal@openssh.com"
+        uint32          sender channel
+        uint32          initial window size
+        uint32          maximum packet size
+        string          socket path
+        string          reserved for future use
+
+The reserved field is not currently defined and is ignored on the
+remote end.  It is intended to be used in the future to pass
+information about the socket file, such as ownership and mode.
+The client currently sends the empty string for this field.
+
+Similar to tcpip-forward, streamlocal-forward is sent by the client
+to request remote forwarding of a Unix domain socket.
+
+        byte            SSH2_MSG_GLOBAL_REQUEST
+        string          "streamlocal-forward@openssh.com"
+        boolean         TRUE
+        string          socket path
+
+Similar to cancel-tcpip-forward, cancel-streamlocal-forward is sent
+by the client cancel the forwarding of a Unix domain socket.
+
+        byte            SSH2_MSG_GLOBAL_REQUEST
