2014.64 - Sunday 27 July 2014

- Fix compiling with ECDSA and DSS disabled

- Don't exit abruptly if too many outgoing packets are queued for writev(). Patch
  thanks to Ronny Meeus

- The -K keepalive option now behaves more like OpenSSH's "ServerAliveInterval". 
  If no response is received after 3 keepalives then the session is terminated. This
  will close connections faster than waiting for a TCP timeout.

- Rework TCP priority setting. New settings are
	if (connecting || ptys || x11) tos = LOWDELAY
	else if (tcp_forwards) tos = 0
	else tos = BULK
  Thanks to Catalin Patulea for the suggestion.

- Improve handling of many concurrent new TCP forwarded connections, should now
  be able to handle as many as MAX_CHANNELS. Thanks to Eduardo Silva for reporting
  and investigating it.

- Make sure that exit messages from the client are printed, regression in 2013.57

- Use monotonic clock where available, timeouts won't be affected by system time
  changes

- Add -V for version
