via JS Socket->xpms_accept().
Also, use do_js_close() to eliminate some repeated code in js_socket.c.

(the multisock stuff already logs this for each interface and port).

calling putcom() with a len value of 0 (which triggers an auto-string-length
grab via strlen() which should be 0 - but.. meh).

the startup->socket_open() callback wasn't being called.
I'm not sure if this is correct with the *nix Spy socket stuff however.

I wasn't expecting to do this, since SFTP is often viewed as "better", but
SFTP doesn't have a specification, the implementations don't follow the
specification drafts that are out there, and the whole sharing a port between
file transfer and terminal server thing is irritating.

This has only been tested with lftp, but it seems to work.

Also add add_public_key() and get_public_key() methods to CryptKeyset.
Not tested yet, but this should be everything we need to finish up
LetSyncrypt.

This class allows saving and loading private keys.  It doesn't currently
allow saving or loading *public* keys, since they require certificate support
which we don't yet have in our JavaScript Object Model.

I'll fix the JSDocs build in a minute.

buffer if full. So now everything that uses outcom (including JS
console.write) now includes a retry. The lower-level non-retry outcom()
was renamed _outcom() (and is used by outcom).
Added new Ctrl-A code: Ctrl-AF - enables the blink attribute, but only
if/when a blink font was activated in the terminal. Lower-case 'f' refers
to the normal-intensity blink-font. Uppercase 'F' refers to the high
intensity blink-font. This allows you to mix fonts in text/menu files
and not have annoying blinking text in non-supporting terminals. This is
the first Ctrl-A code to be case-sensitive.

Over-hauled the ANSI detection a bit too.

Previous versions of cryptlib defaulted to zero, but that's no longer the
case, and zero won't work.

or more have elapsed since the last system password (SY:) prompt. Similar
to Linux 'sudo' command. Might make this time configurable rather than
hard-coded at some point, but 15 minutes seems like a good default.

Fixed MSG_ATTR @-code (missing SPAM attribute)
New text.dat line: FileHdrDescSeparator, displayed between file detail display
(name, date, uploader, etc.) and extended description, if there is one. This
is used to execute showfileavatar.js.
New JS 'bbs' object properties:
- file_name

Inspiried by Lon Seidman's now infamous (but likely common) Synchronet sysop
blunder (removing a file rather than downloading it while demonstrating his BBS
on his youtube channel:
- New text.dat line: RemoveFileQ <- using this rather than the vague:
  AreYouSureQ, when prompting to remove a file
- The sysop command to remove files from the batch file flagging prompt has
  been changed from 'D' (delete) to 'R' (remove).
- The 'D' command from the batch file flagging prompt may now be used for
  immediate Download of any flagged file(s).
- When flagging files with '*', treat the same as '*.*'

- If the first lines sent after a key-press are blank lines, don't count them
  in the line-counter (lncntr) - maximize the viewable data before pause.
- Assume tabs chars are expanded to 8-space tab-stops when detecting auto
  line-wrapped output (e.g. when ;LISTing text files with tabs)

server log) using the new magic sbbs_t::lputs().
No more SSH errors if an SSH client's IP is blocked in ip.can (trying to send
the block msg).
New SSHConnectTimeout cfg value (in sbbs.ini [BBS]), defaults to 10 seconds.
Previously, fails SSH connections could block the bbs_thread for 30 seconds
(the Cryptlib default network connection timeout).
Overhauled a lot of the SSH-related log output to make it less chatty and more
meaningful.
getmail() is now more flexibility with regards to filtering by attribute flags
(not just SPAM).
Allow SPAM header attribute to be toggled with sysop 'C' command.

Fixed warning: converting to non-pointer type ‘CRYPT_SESSION {aka int}’ from NULL.
Fix the race-condition crash Deuce reported:

The output RingBuf can't be destroyed while the passthru_input_thread is still

Active connections (sessions) would be interrupted if another SSH
connetion came in and failed (e.g. IP was blocked or failed negotiation).

  Automatically detect child sub-directories and make them available as virtual
  directories for users to download from - only useful via FTP currently.
* Implemented Sorting options for Message Groups and File Libraries:
  Sub-boards within groups and directories within library can now be
  automatically sorted based on the sysop's chosen sort field (long name, short
  name, or internal code)
  - Required that sub-boards are now stored/saved in msgs.cnf based on groups
  - Required QWKnet hub sub-board reference dynamic renumbering
* Implemented "Template" toggle option for sub-boards and file directories:
  A sub-board or directory marked as "template" will be used for newly created
  (or imported) subs/dirs for that group/lib. Clone Options via SCFG will now
  use the "template" item as the source of the cloned settings, if available.

badip.msg wasn't be sent (display to) the IP-blocked user before disconnecting.
This regression was introduced in rev 1.632 of this file when the temp IP-ban
feature was implemented.

in some contexts was too vague (e.g. the 'c' command output from the sbbs
console).

- There was a bug in the first implementation that would cause subsequent
  connections from a non-exempt IP address to be rejected: client_on() is
  called multiple times for a single connection - oops.
- Successfully logged in clients are now *not* counted against the concurrent
  connection limit. This way if a node hangs, the user at that IP can still
  connect/login to another node. The client has to be fully logged-in to be
  excluded from the connection count.
