htpp-1.20: - Feb 11 1999 - Hessu
	- Removed everything that isn't needed (the clients, mailgate stuff, 
	  unnecessary commands, bundled libraries).
	- Ran it through indent -kr -i8.
	- ANSIfied function prototypes.
	- Cleaned up Makefile.
	- Made tnos.c it's own module (not #included in the end of user.c).
	- Fixed header files to include the right stuff.
	- Removed all #ifdef __OS2__ stuff. The port was for some old
	  and obsolete TCP/IP package anyway.
	- Made it compile without barfing using -Wall -Wstrict-prototypes.
	- Removed register keywords from variables, compilers are smarter
	  than us these days anyway.
	- Added some more error checking and logging in places.
	- Fixed write_pid().
	- Fixed a couple of bugs in destination list handling.
	- Added a better and cleaner configuration file parser.
	- Separated command line argument parsing and implemented it
	  using getopt().
	* Dumped libwrap and added access control lists in the config file
	  (thanks go to Tomi, OH2BNS).
	
htpp-1.21: - Mar 13 1999 - Hessu
	- Removed gethostbyaddr() from accept_connect_request(), was only
	  used for logging, mostly useless and made accepting connections
	  from non-resolvable hosts with unreachable DNS servers REALLY
	  slow, blocking the whole server.
	- Added checks for some illegal configuration file statements.

htpp-1.22: - Apr 25 1999 - Hessu
	- Fixed a security bug (allowing an DOS attack) in the /help command.
	- Added a workaround to keep some certain ancient gods quiet.
	- Ugly hack involving a sleep(10); to avoid fallback to primary link
	  from looking like a loop and causing link vibration. Really closes
	  the backup link before relinking and waits for the information to
	  (hopefully) propagate to the primary server.
