Patch for resolving port specifications with getservbyname

Is there a reason ssh doesn't consult services(5) for port numbers?

This has irked me forever.  I'd rather write ssh -L icb:localhost:icb
instead of ssh -L 7326, wait, 7236, uhm, grep icb /etc/services...

I don't think there is any syntactic ambiguity since Unix sockets
already must contain a '/'.

The patch below adds this:
* Try to resolve a port specification with getservbyname(3) if a
  numeric conversion fails.
* Make the "Port" option in ssh_config handle its argument as a
  port rather than a plain integer.

All other command line switches and configuration file options
already use a2port().

This passes the existing regression tests.
