Fix TELNET to interoperate with buggy servers.

Browse Source 
Here is the patch to get telnet to talk to a modern telnetd.  This
weekend I will finish adding DHCP to IMP and doing some more cleanup
on code.

The basic change was to expand the telcmd to several calls to remove
the flush at the end of the macro.  Modern telnetd seems to want
WONT/DONT commands not to span packets.
