Based on RFC 854: TELNET Protocol Specification, by J. Postel and
J. Reynolds

Example:

>>> from telnetlib import Telnet
>>> tn = Telnet('www.python.org', 79)   # connect to finger port
>>> tn.write('guido\r\n')
>>> print tn.read_all()
Login       Name               TTY         Idle    When    Where
guido    Guido van Rossum      pts/2        <Dec  2 11:10> snag.cnri.reston..

>>>

Note that read_all() won't read until eof -- it just reads some data
-- but it guarantees to read at least one byte unless EOF is hit.

It is possible to pass a Telnet object to select.select() in order to
wait until more data is available.  Note that in this case,
read_eager() may return '' even if there was data on the socket,
because the protocol negotiation may have eaten the data.  This is why
EOFError is needed in some cases to distinguish between "no data" and
"connection closed" (since the socket also appears ready for reading
when it is closed).

To do:
- option negotiation
- timeout should be intrinsic to the connection object instead of an
  option on one of the read calls only

    An instance of this class represents a connection to a telnet
    server.  The instance is initially not connected; the open()
    method must be used to establish a connection.  Alternatively, the
    host name and optional port number can be passed to the
    constructor, too.

    Don't try to reopen an already connected instance.

    This class has many read_*() methods.  Note that some of them
    raise EOFError when the end of the connection is read, because
    they can return an empty string for other reasons.  See the
    individual doc strings.

    read_until(expected, [timeout])
        Read until the expected string has been seen, or a timeout is
        hit (default is no timeout); may block.

    read_all()
        Read all data until EOF; may block.

    read_some()
        Read at least one byte or EOF; may block.

    read_very_eager()
        Read all data available already queued or on the socket,
        without blocking.

    read_eager()
        Read either data already queued or some data available on the
        socket, without blocking.

    read_lazy()
        Read all data in the raw queue (processing it first), without
        doing any socket I/O.

    read_very_lazy()
        Reads all data in the cooked queue, without doing any socket
        I/O.

    read_sb_data()
        Reads available data between SB ... SE sequence. Don't block.

    set_option_negotiation_callback(callback)
        Each time a telnet option is read on the input flow, this callback
        (if set) is called with the following parameters :
        callback(telnet socket, command, option)
            option will be chr(0) when there is no option.
        No other action is done afterwards by telnetlib.

        The first argument is a list of regular expressions, either
