PATCH: _hosts, _hostports, _telnet and _socket

[Tanaka Akira <akr@jaist.ac.jp>]

I made `_telnet' and `_socket'. They may complete port number and
names depend on a host argument.

So I extended the format of the variable `hosts' to be able to contain
port numbers and names as:

hosts=(... host:port ...)

For that purpose, I modified `_hosts' to handle this format and made
`_hostports' to complete port numbers and names depend on a host.
