Oddly, the Identity Lookup checkbox was obscurring (hiding) the Hostname
Lookup checkbox, so that becomes visible/available again.

(not practical to disable JavaScript for the terminal server any longer)
and added the NO_SPY_SOCKETS option.

section of the sockopts.ini (if there is one) rather than the [tcp] or
[udp] sections. This resolves the errors:
      term xxxx !ERROR 95 setting socket option (TCP_NODELAY, 1) to 1
which started appearing after the TCP_NODELAY option was added to the
[tcp] section.

a target port number.
The port and hostname arguments can now be supplied in any order.
Added debug-level log output with the host/port we're trying to connect to.
Include the socket error value in the failure to connect log message.

TCP connection actually failed. This bug only appeared to affect *nix
systems. This bug appears to be very old, introduced in rev 1.74 of
this file (Mar-2003) by yours truly.
From the Linux 'connect' man page:
EINPROGRESS
              The  socket  is  nonblocking  and the connection cannot be i
              completed immediately.  It is possible to select(2) or poll(2)
              for completion by selecting the socket for writing.  After
              select(2) indicates writability, use getsockopt(2) to read the
              SO_ERROR option at level SOL_SOCKET to determine whether
              connect() completed successfully (SO_ERROR is zero) or
              unsuccessfully (SO_ERROR is one of the usual error codes listed
              here, explaining the reason for the failure).

We weren't doing the 'getsockopt(SO_ERROR)' part.

Wrap all read_*_cfg() and write_*_cfg() calls with simple functions that
display popup messages that the Reading or Writing is being performed.
There was already copy/pasta everywhere for the Reading ... cnf files, but
nothing for writing.

pathname (directories must end in a '/'). Unlike getfname() which returns an
empty string if passed a path ending in a '/'.
Useful with glob(.., GLOB_MARK).

getfname() on a path that ends in a slash, returns an empty string pointer.
Fixed-up some logging output around listing creations.

- use GLOB_MARK to eliminate calls to isdir() in loops
- use stat() rather than calls to flength() and fdate()
- don't call getfiledat() if getfileixb() failed
- profiling info-level log msgs added for index/listing generation, e.g.
  "detailed listing (3459 bytes) of /main/SBBS (45 files) created in 2 seconds"

Fixed bug with indexes generated for directories with the
"Access Files Not In Database" option enabled, files not in database were
excluded from the generated index (e.g. 00index, 00index.html).

rather than calling both flength() and fdate() (which both call stat()), just
call stat() once and use the result for both file size and date/time.

There's no reason to call access() before stat() since stat() will fail
(return -1) if the file does not exist.

Loads child scripts (finger.js, sbbsimsg.js) quicker.
Note: irc.js can't be load()ed from here because it calls exit().
Now using appropriate strings from text.dat (R_Chat, ON, OFF).
Added modopts.ini [chat_sec] irc option (disable IRC access by setting to false).

console.ctrlkey_passthru state.
As it was, if the irc.js abended, many ctrl-keys (e.g. ^C) would not work
after exiting. A lot of scripts that much with the console.ctrlkey_passthru
have this/similar issue and this is a simple but very reliable fix.

(mostly migrated from exec/finger.js).

tickit.js version pulled from $ID string in .js file.
tickit version used in Created by line.
tickit version used in Path line.
utc time stamp of processing used in Path line per FTS-5006.001.
per area uploader.
address selection:
   per area aka matching in From and Path lines.
   per area source address in From and Path lines.
   global aka matching in From and Path lines (original addressing method).
   global source address in From and Path lines.
   main FTN address from system.fido_addr_list (preferred but last in line with
the above overrides).
can use domains on linked systems' addresses in sbbsecho.ini again.
can use domains on any address in tickit.ini.
domains are NOT currently written to the generated TIC files to avoid creating
possible problems for other TIC processors.
force replace is available globally and per area in the ini and not only the
command line.

the beginning of a SAUCE record and the end of very old MS-DOS text files.
Added support for ESC[1;1f/H (home cursor) and ESC[0J (clear to EOS) sequences
(converted to the equivalent in Ctrl-A codes).
Output Ctrl-A characters in uppercase, as they were documented and as is
common practice.
Covert ESC[xB and ESC[xD to the appropriate Ctrl-A sequences rather than
converting to ASCII ctrl chars (CR, LF, BS).

Ctrl-AJ (clear to EOS)
Ctrl-A` (home cursor)

Oct-14-2018:
It turns out, PabloDraw actually inserts a Ctrl-AZ sequence at the end of .msg
(and presumably Synchronet .asc) files it edits - before the SAUCE record.
This resulted in a printed Ctrl-Z character (arrow pointing right) in most
terminals when viewing text/menu files created or edited with PabloDraw. :-(
So, now Ctrl-AZ (uppercase) will revert to the previous definition:
premature end-of-file (EOF)
and a Ctrl-Az (lowercase) will output a Ctrl-Z (substitute) character.
I'm not a big fan of case-sensitive Ctrl-A codes, but frankly, running out of
chars and I already started this pattern with the Ctrl-AF/f sequences.
Hopefully there's no existing software that is/was putting Ctrl-Az (lowercase)
in files, expecting that to trigger a premature EOF. I certainly was not.

- this change is dependant on the updated load/modopts.js.
Cache the presence_lib and nodelist options in the bbs.mods object to speed
up the re-loading of this script from the BBS. This means that changes to the
presence_lib or modopts.ini will require the user log-off/back-on to experience
the changes (only for the nodelist module).

of the user_age_and_gender() method.
Changed options.web_inactivity_timeout to just options.web_inactivity to be
more consistent with the existing modopts.ini [web] option naming.

You may now request the value of a single modopts.ini key value (optionally
specifying a default option value), via:
    optval = load({}, 'modopts.js', 'modname', 'optname');
or:
    optval = load({}, 'modopts.js', 'modname', 'optname', default_optval);

This usage will return just a single option value rather than an object
containing properties reflecting all the options in the [modname] section.
The pre-existing usage is still supported (and preferred in most cases).

(default: 'browsing' - to match web UI verbiage).

(includes web v4 users logged-in/recently-active).
Added 'W' / who's online command to those shells that didn't have it
(except for Wildcrap!) - equivalent of the Ctrl-U global hot-key.

'include_web_users' is set to false in the [nodelist] section of the modopts.ini
Document the arguments supported in comments.
It's no '-noself' instead of '-notself' to exclude own node from output.
Also more/better "use strict" enforcement.

Provide better example of constructing/using User objects.

Added more comments and use 'var' when defining a new variable
(though 'const' might be better here, don't want to risk that change atm).

numbers beginning w/0 are interpretted as octal by parseInt() by default.

0-byte .msg files are normal and do not mean a msg is waiting for the user.

include_location (defaults to true)
New comments at the top documenting the modopts.ini settings available.
Include misc flags (M for msg waiting, P for do-not-disturb) in web user status
active-users.json was excluding node with the POFF (do not disturb) flag set,
thus making the do_not_disturb property kind of moot - fixed.

Added properties to web_user object: do_not_disturb and msg_waiting

The active-users.json response now includes a 'prot' (protocol) object, just in
case we want to use that in the future.

derived from a portion of ecwebv4's ndoelist.js.
TODO (echicken, help!): fill-out the 'action' property from the web session and
double-check on the logontime value (can we get this from the session blob?).

Much of the code in these 2 modules was moved/migrated to the new presence_lib
and made more reusable/modular.

Migrated mostly from exec/nodelist.js, some from fingerservice.js.
