Over-hauled the ANSI detection a bit too.

and Ctrl-N (next) instead Ctrl-U and Ctrl-D as that wasn't going to work with
fseditor.js's (Ctrl-U is quote).

sequence is currently just the <esc>[V and <esc>[U sequences (supported by
SyncTERM).

Server via the new 'V' command from the Reading Mail prompt allows you to
toggle between all mail (including SPAM, the default), SPAM only, or HAM only.
Also added a new '/' (search text) command from the reading mail prompts.
Mail imported before the mailsrvr added support (recently) for the MSG_SPAM
attribute flag will not be counted/filtered as SPAM.
SBBSecho will have a commit (next) to support the new loadmail() usage, it
will not compile until then.

  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.

Using this flag swaps the alias and real-names as passed in the first 2
fields of the RLogin authentication/negotiation (client-user-name and
server-user-name).

(currently only via FTP) - simiilar to the global FTP option: DIR_FILES.
I intend to extend this option to the terminal server as well.

If anybody actually hit these limits I'd be impressed, but it's not impossible.
65535 (-1 as an int16_t) is a special value used to indicate an "invalid" item.

globally (using a new macro in sbbbsdefs.h: STR_UNKNOWN_USER). "<unknown>"
in some contexts was too vague (e.g. the 'c' command output from the sbbs
console).

Removed some unused constant definitions/macros.
Updated copyright date (to 2016).

no longer ignores Ctrl-Z characters (CP/M EOF) by default. If you want the
old behavior (Ctrl-Z characters not displayed, just skipped), specify the
P_CPM_EOF mode flag.

function where the error is being reported from. So the WHERE macro now
contains the __FUNCTION__ "macro" and the various js*.c files that use the
WHERE macro to report errors had to be updated too.
Also, the 'access' argument is now being passed as a signed long rather than
unsigned long. Status/return values are often passed in here (e.g. from smblib)
and may be negative. This argument was being displayed with %ld but wasn't
being passed in as a signed value, so on 64-bit long systems, negative numbers
were just printed as large (4M+) numbers.
Also, no need to call getfname() in errormsg() since this is embedded in the
WHERE macro (since 2009).

Introduced a better progress indicator (similar to poll results), using the
backfill() method. 2 new attr.cfg fields allow the progress indicator colors to
be configured separately from poll results (though they default to the same
white on magenta). This new progress indicator is used when loading msg ptrs
and scanning for votes. I will be using it while performing other searches
(e.g. file libraries/dirs) as well.

- Include Kludge Lines     (Yes)
- Include VOTING.DAT File   (Yes)
- Include HEADERS.DAT File   (Yes)
- Extended (QWKE) Packets    (No)
- Exported Ctrl-A Codes    (Strip)

SBBS/QWKnet nodes now have more control over the REP packet files created
by their systems. If the "uplink" (hub) is complaining about receiving
unsupported files (e.g. VOTING.DAT) or kluge lines (e.g. @TZ), just turn them
off.

Also, Ctrl-A codes may now be retained in QWKnetmail. And the @REPLYTO kludge
line enabled for the first time (!).

New MsgBase header propeties:
- total_votes (total number of votes this msg or poll has received)
- tally[], an array of 16 numbers indicating the total votes for each poll answer
  in the case of a normal message, tally[0] is the same as upvotes and tally[1]
  is the same as downvotes.
This should complete what echicken needs to display polls and voting results
in his web UI.

be used in displaying poll results.

- Users can be restricted from voting with the 'V' restriction
- Sub-boards can be disalbled for voting in SCFG
- VOTING.DAT can be include/excluded from QWK packets via user cfg
  (when a VOTING.DAT is received in a REP, the user cfg flag is auto-set)
- Adds several new text.dat lines (if not present in yours, uses the default)

What's not yet implemented:
- Notification of votes on your posted messages
- Method to view/audit all votes
- Polling
- Any special handling to auto-exclude votes from msg-related JavaScripts

The beginnings of an SMB-based voting system - very experimental:
The concept is that a "vote" message can be used to reply to:
1. A normal message, as either an upvote or a downvote, ala social media
2. A poll, polls can either allow a single choice answer or multiple answers
Vote messages won't be visible as normal messages (e.g. when reading messages
online) and SMB processing software (e.g. SBBSecho) should ignore these
messages because they have no body text.
Polls are going to need more work, but the idea is to have the poll question as
a single (newly defined) hfield and the possible answers as dfields.

in the default user config, a scansubs(SCAN_ALL) will still not do a new
file scan.

Don't report a JavaScript warning ("Disconnected") until the OperationCallback
has been executed 10 times with the user offline. This gives the executing
script ample time to recognize the disconnected state and exit gracefully.
Script that do not check/notice that the user has disconnected will still be
auto-terminated (by default) and this warning will still be logged in those
cases. The value 10 was picked at random and appears to work fine.

When checking the terminated value, check all parents until you either find
one that is TRUE, or run out of parents.

Do *not* go up the chain of parents when *setting* terminated.  Background
threads still can't set it (TODO?).

New Features:
- Multiple bindings for each service
  Use comma-separated interfaces on Interface= lines in the ini file.
  Default is now "0.0.0.0,::"
- IPv6 support
- TLS support for the webserver and (non-static) services
  New TLS option in services.ini (ie: Options=TLS)
- Decrease LEN_SCAN_CMD to 35 chars, increase the CID field to 45 chars,
  and rename the MAIL_CMD string to IPADDR.  I think this frees up the
  note field for SysOp use.

scanposts(), and listsub(). These functions are exposed in the JS 'bbs' object
as scan_subs(), scan_msgs(), and list_msgs().
Wherease previously, all of "your messages" (messages addressed to you)
would be found/displayed if the user answered (Y)es to the "Subjects Only?"
prompt, and only un-read message (to you) would be displayed if they answered
(N)o to the "Subjects Only?", providing long-standing confusion about the
different behavior, now the user is prompted whether to display un-read
messages only (in scansubs/scanallsubs), and in the case of the logon
question to "Search all subs for un-read messages to you?", only un-read
messages are listed/displayed, regardless of how the user answers the
"Subjects Only?" question.
SCAN_UNREAD is only applicable when combined with SCAN_TOYOU.

Added new commands to the msg reading prompt: 'N' (list new messages), 'U'
list un-read messages to-you.

2 new text.dat entries: DisplayUnreadMessagesOnlyQ and NoMessagesFound

of the new user process - could be used to display a file or execute a script
via @-code.
Introduced the "Color Terminal" new user question toggle (defaults to off).

- this option has been a default option flag for 10 years
- this option was introduced *before* the RLogin password capability
- Synchronet now always expects the login-ID (alias) to be the 2nd string
received during RLogin connections (called 'server-user-name' in RFC 1282.
* Now storing the complete terminal type/speed string received during RLogin
connection in the bbs.rlogin_terminal property (sbbs_t.rlogin_term in C++).
* bbs.rlogin_gate() is over-hauled:
- arguments are: address, client-user-name, server-user-name, terminal, mode
- if existing JS module assumes this to be: address, server-user-name, password
  those scripts will need to be updated to reflect the correct argument order
- all arguments beyond the first are now optional
- the terminal string can now be passed-in
* Deprecated the telnet gateway option: TG_SENDPASS (the 'password' if desired
to be sent as the 'client-user-name' can be specified as an argument and this
option sent the password as the *second* RLogin string ('server-user-name'),
which was always wrong.
* sbbs_t::telnet() can now accept the terminal string as an optional argument.

or 'longs'. Amazing that no one noticed.

If an external progarm is configured (in SCFG->External Progarms) is configured
to "execute on event" set to "Local/Sysop Chat", then that program will be
executed when the remote user is "pulled" into sysop-chat (e.g. via F10 key in
sbbsctrl) rather than running the normal built-in chat.

Added new telgate flag: TG_NOLF.

added bbs.rlogin_gate method: bbs.rlogin(addr,user,pass,mode);
disable "raw input" mode for rlogin_gate connections. not sure why this is the fix or why it was the problem, but no side effects are noted at this time.

Apparently, it IS defined on Linux and FreeBSD, but is not currently
defined on OpenBSD (but I bet it used to be!).  This should fix the strange
zip behaviour reported by khelair.
