AFD

It is now possible to configure AFD to send a STAT at certain intervals to keep
the FTP control connection alive. It is now possible to resend files via the
show_olog dialog even when the "age-limit" and/or "trans_rename" options are
set. SCP1 support was improved so that it can rename files. The source code
compiles under HP-UX 10.20 again. A bad rename bug was fixed. Compatibility
with Lesstif was improved.

Fixed a memory leak in afd_ctrl dialog, the view_dc dialog now shows the directory options, and made appending of files with FTP safer, by checking the date of file as well, and not only the file name.

Files of zero length are now always copied correctly, fixed the directory option "delete unknown files" which wrongly deleted files in the queue as well, new config file option "delete queued files", a new dialog to view what files are being queued by AFD has been added, it's now possible to delete files from the queue, the format of the HOST_CONFIG file has changed, two new parameters have been added to store the status of the host and some protocol specific details, it is now possible to set the idle time of the remote FTP server, and AFD has been ported to AIX.

Process FD will not always start a new process to send files. Instead, it will
try to take an existing process. This should reduce the total number of
connections and process creations. The copy function has been changed so that
it uses less memory. The process afdd will not be started automatically if this
is not set in the AFD_CONFIG file. Lots of minor bug fixes were made.

Two bad bugs fixed in process dir_check. When one directory receives files at a very high rate, dir_check can end up in an endless loop serving only this directory. The other bug could cause very long delays when scanning the directories.
