for getstr() to be able to return when user right-arrows off end of string
(for use in msgeditor).

Issue raised by Dumas Walker (CAPCITY2) on DOVE-Net: apparently some new
sysops run this script before their configured hostname (e.g.
mybbs.synchro.net) is valid or their mail server has been tested (can
successfully receive Internet e-mail).

This attempts to address this concern by:
1. displaying a warning that it's important that the address given is valid
2. attempt to validate that the host portion of the provided address is valid
   (has a DNS address record or MX record)

Uses dns.js for MX-record lookup - thanks Deuce!

This script does not validate that the email host can actually receive mail
or that the name portion of the mail address is valid: that would require an
outbound connection to the host's TCP port 25, which may be blocked by ISPs
(if remote) or if its a local server (e.g. the same machine as the BBS), that
wouldn't confirm that its reachable by Internet hosts. And not all mail
servers support the necessary SMTP commands to validate recipient addresses.

CCl4 sends an ENQ character in the login screen, and sends an ENQ
which will auto-fill your username.  Also, if you enter six zeros
into the username, it will take you to the password field.

With ten zeros, this means it's impossible to log in to CCl4.

Fixes Night Owl

And have it return bool, like the others. The error logging is different
(not using errormsg), but I think that's okay.

Beautified the output a bit.

If this were const to begin with, would have caught the previously
fixed bug with the -lib option clobbering it.

... trying to get to bottom of user.tab corruption reported in issue #797.

Also, don't need to seek in lockuserdat() since we always call seekuserdat()
first.

Trying to get to the bottom of user.tab corruption (issue #797).

Though we've had the auto-filtering feature for about a year now, with
expiration dates supported/added to every trash record, nothing was
removing the expired trash/filter items. Until now.

Check the size of your text/*.can files: if they're really big, this is
the solution.

Not yet building for Windows

Sysops will want to run this periodically (monthly?), e.g.
	trashman /sbbs/text/*.can

Just scream on stderr, and screw things up in the window.

The palette is used to construct the blank screen buffer using
vmem cells, so the background would be in screwy colours when
connecting for modes that don't use the CGA 16-colour palette.

Fix to Nelgin's reported error:
line 199: TypeError: lib.parse is not a function

Root-caused this problem to read() failures which are now caught and logged
rather than zeroing out the statistics fields.

Allow filtering/blocking email based on the name portion of email header
fields.

I think this map may be the final one.

Not tested on Windows.

I don't expect anything actually uses this...

This is so gross... outputting any character depends on every
character above it, so it must be checked every time.  If the state
was ste up differently, this could be avoided, but it's not, so it
can't.

For v2, I'm going to want to store some per-line data in a separate
struct so I can track this.

(these options follow the password by one or more spaces)

I implemented these based on AreaFix v1.10 User's Guide, at Ragnarok's
suggestion/request. I didn't test them, so looking forward to getting some
test results.

The -L and -Q options are functionally identically to the %LIST and %QUERY
AreaManager commands, while -R ads a little efficiency by combining +areatag
(add) and %RESCAN <areatag> requests in a single command.

Apparently AreaFix and other area managers assume password never have spaces
in them, so they can support additional arguments following the password in
the AreaFix request.

This change also now disallows setting AreaManager passwords with spaces in
them.

I don't yet support any of the additional AreaFix request options (e.g. -L,
-R, -Q), but am considering it.

A bunch of sprintf() -> snprintf() conversions are included in this commit
(better string buffer security, probably eliminate a Coverity issue or two).

Lowered the intensity of the green '3' (happier on my red-green
colorblindness).

Result looks more like the original Windows versions of this game.

ddfilelister: Clear the console line counter before any searching, etc., to prevent screen pauses. This should help with issue #806
