and send_mlsx().
Fix numerous printf-style argument bugs, many in the TLS and MLSx support.

Put "TLS" in the failure log messages rather than repeating "FTP".

Was this pasted from somewhere else?

- Since rev 1.556, mailproc_to_match[] would only ever contain one mail
  processor (index) value, even if the RCPT TO address matched multiple
  mail processor "To" keys in mailproc.ini, so only the first-matching
  mail processor (with a "To" key) would be executed for the msg.
- mailproc_match, meaning the destination was a non-passthrough
  external mail processor, in which case the destination (RCPT TO) address
  may *not* match a valid local user account, would be set for *passthru*
  mail processors potentially resulting in the following error (and an
  undelivered mail message): !SMTP can't deliver mail to user #0
  only set mailproc_match to a valid mail proc index if the recipient matches a
  non-passthru mail processor.

instead of stdout.

(black on black) as this can inadvertently "hide" text for ANSI users
(e.g. poll comments, when reading a poll message). Set to 7 (lightgray)
instead.

not known/available (e.g. certain types of SSH login failures).

to use this function in bbs_thread() for SSH failed login attempts and thus
enable the perm-IP-filtering (LoginAttemptFilterThreshold) functionality.
Right now, it's only a "bad login" if the "Getting channel type" doesn't
return "session", but we could (and likely will) use it for more SSH login
failure modes which indicate a likely hack-attempt.

had a "replace" option that did something differnet (enabled parsing of the
REPLACES verb) - don't want to confuse sysops now. :-)

description string ('node') in SSH-related log messages (e.g. errors) from the
output_thread: No more "Node 0" log entries from here.

    "Deprecated file open mode: 'e'"
If this is your script generating this warning, either remove the 'e' from
the File open() mode string (it had no effect anyway) or change to 'x' to
get the real/working exclusive-open functionality (added in v3.17).

(e.g. for a QNET hub or timed event).

simply ignored when converted to the underlying open mode passed to sopen().
Deprecate this flag and log a warning when it is detected as used in a script:
Deprecated open flag used: 'e'
Added 'x' (exclsuive-open) mode flag which:
1. was tested to work as intended
2. is consistent with the C11 standard for fopen() mode flags
3. won't cause existing scripts to suddenly break

command-line, treat all .TIC files as they have have a "REPLACES" clause.

This prevents leaving all sockets open until the script exits.  It would
be better to reuse the existing socket when it's already connected to the
right place, but this is easier for now.

these errors are coming from.

header_rows = number of lines occupied by the header graphic
The normal ansiview 'window' will be pushed down by header_rows lines,
and the header graphic will be displayed above it.

new user signup process with that name (just fall-through to a normal login
prompt).

domain/zone-map configuration to be used - always.

domains configured in sbbsecho.ini
('domains' is always undefined at this point, <shrug>).

(Argus and Mystic's BinkP mailers don't support encryption).

Added node address to some authentication failure warnings.

Created struct fidoaddr (5D address), though it's only used (so far)
in pktdump.c - doesn't really need to be packed.

If you're not using BinkIT (you're using some other FidoNet mailer), you can
safely ignore all the settings/options.
A lot of the online help for the new settings/menus needs to be written
still and the wiki now needs a lot of update to reflect the changes.
The "title" of this program was changed, again, from "SBBSecho Config" to
"[Synchronet] FidoNet Config" since it configures more than just SBBSecho
now.

(the upgrade renames binkit.ini and ftn_domains.ini to *.old).

Use "jsexec binkit upgrade" to upgrade your existing .ini files if you're
already running BinkIT 1.x.
echocfg v3.04 may now be used to set all the BinkIT settings and domains
(in sbbsecho.ini).

(note: some of the key names were changed), run "jsexec binkit upgrade"
to upgrade your existing .ini's (if you have them).
Removed support for sbbsecho.cfg.
