 *
 *			File Transfer Protocol (FTP) Client
 *			for a WorldWideWeb browser
 *			===================================
 *
 *	A cache of control connections is kept.
 *
 * Note: Port allocation
 *
 *	It is essential that the port is allocated by the system, rather
 *	than chosen in rotation by us (POLL_PORTS), or the following
 *	problem occurs.
 *
 *	It seems that an attempt by the server to connect to a port which has
 *	been used recently by a listen on the same socket, or by another
 *	socket this or another process causes a hangup of (almost exactly)
 *	one minute.  Therefore, we have to use a rotating port number.
 *	The problem remains that if the application is run twice in quick
 *	succession, it will hang for what remains of a minute.

 *	LM	Lou Montulli <montulli@ukanaix.cc.ukans.edu>
 *	FM	Foteos Macrides <macrides@sci.wfeb.edu>
 * History:
 *	 2 May 91	Written TBL, as a part of the WorldWideWeb project.
 *	15 Jan 92	Bug fix: close() was used for NETCLOSE for control soc
 *	10 Feb 92	Retry if cached connection times out or breaks
 *	 8 Dec 92	Bug fix 921208 TBL after DD
 *	17 Dec 92	Anon FTP password now just WWWuser@ suggested by DD
 *			fails on princeton.edu!
 *	27 Dec 93 (FM)	Fixed up so FTP now works with VMS hosts.  Path
 *			must be Unix-style and cannot include the device
 *			or top directory.
 *	?? ??? ?? (LM)	Added code to prompt and send passwords for non
 *			anonymous FTP
 *	25 Mar 94 (LM)	Added code to recognize different ftp server types
 *			and code to parse dates and sizes on most hosts.
 *	27 Mar 93 (FM)	Added code for getting dates and sizes on VMS hosts.

 * BUGS:	@@@	Limit connection cache size!

 * 		400 & 500 errors are ack'ed by user with windows.
 * 		Use configuration file for user names
 *
 *		Note for portability this version does not use select() and
 *		so does not watch the control and data channels at the
