There are other ways to generate forced-upper case expanded @-codes, if that's
what you want.

Fewer duplicates in text.dat make localization, translation to other languages
easier.

So Clang-FreeBSD was warning (in compiles of scfg/scfg*.c by Deuce):
result of comparison of constant 100000 with expression of type 'uint16_t'
(aka 'unsigned short') is always true

Why? Cause a uint16_t's max value is 65535 (less than 100000). Sure we could
have just lowered the UIFC max number of config items to 65535, but that would
have been too easy. And why are these compared-with values of type uint16_t to
begin with? Because most ctrl/*.cnf lists (of configuration items) were
limited to 65535 entries cause ... 16-bit DOS, historically. Now that *.cnf
files aren't used, we could just increase these scfg_t.*_total type sizes from
16 to 32-bits, yeah? The result is this commit.

I went to (signed) int so we could still keep -1 as the special illegal
sub/dir num value (e.g. INVALID_SUB, which is sometimes used to indicate the
email message base). Theoretically, 2 billion configuration items could be
supported in these lists, but SCFG will limit you to 100000 anyway. So there's
a whole lot of s/uint/int in this commit.

I'd be very surprised if this doesn't result in some new GCC/Clang warnings,
but at least the old "comparison of constant 100000" warnings are now gone!

Does exactly the same thing, no change in behavior and unlikely there's any change in performance.

Also resolved some 32 vs 64-bit 'long' issues/ambiguities that have long-remained. :-)

This commit also removes logon.lst file support.

There's a TODO block remaining in js_user.c for setting portions of a user's birthdate (e.g. just the year or month or day).

Don't need no stinking pre/appended white-space in our filenames!

This won't impact Synchronet as it has a separate signal handling
thread, but we still need to behave properly for processes that
don't.  I'm also saying that ENOMEM does not indicate a disconnection,
though it may be better to pretend it was disconnected...

SCFG for Win32 is linked against a load_cfg lib that builds withOUT SCFG defined, so these compiled AR elements were allocated and then many SCFG operations (e.g. copy/paste, create new) would copy the allocated ARs to another configuration and then be subjected to double-free upon exit/clean-up (resulting in exception or crash).
Just get rid of this cruft and some other related RAM-byte-saving hold-overs from the MS-DOS days.

(JS bbs.post_msg()): If the WM_QUOTE mode flag is *not* set, then it will auto-
create the quote file (quotes.txt) and add the WM_QUOTE mode bit before calling
sbbs_t::writemsg(). So if existing JS scripts call bbs.post_msg(..., WM_QUOTE)
with a custom-created quote file (e.g. with msg tails), that'll still work as
before (e.g. DDMsgReader.js).

bbs.email() and bbs.netmail() now support an optional reply_header_object
argument which works like bbs.post_msg(). These methods (and the underlying
C++ methods: sbbs_t::email(), netmail(), inetmail(), all auto-create the
quote file now, when the WM_QUOTE mode flag is *not* set.

The auto-created quotes.txt now includes the plain-text version of MIME-encoded
messages.

the bbs.post_msg(), email(), and netmail() methods now all support reply
header objects that came directly from bbs.get_msg_header() *or* copies of
such header objects (but the auto-quoting feature won't work when supplied
this type of header object). So if passed a header object returned from
bbs.get_msg_header(), we can now use the message base (for auto-quoting) and
the underlying msg storage directly (no JS parsing necessary). This is what
the new js_GetMsgHeaderObjectPrivates() function is used for.

js_ParseMsgHeaderObject() (and the underlying parse_header_object() function)
now supports either an actual internally-generated msg header object (e.g.
returned from bbs.get_msg_header()) or one that is a copy or hand-constructed.

quotemsg() no longer tries to get a copy of the msg index/header. It shouldn't
have to since we can now get to underlying msg storage in the js_msgbase.c
via js_GetMsgHeaderObjectPrivates().

quotemsg() now reads only the plain-text portion of MIME-encoded messages.

As part of this effort, I modernized the method prototypes using default
argument values (e.g. WM_NONE for wm_mode arguments) and removed some
extraneous WM_EMAIL and WM_NETMAIL specifications (these wm_mode flags are
automatically added by the sbbs_t::email() and *netmail() functions).

savemsg() now *does* support reply-IDs/thread-linkage via the additional
'remsg' argument (when non-NULL).

Replaced some use of nulstr with NULL.

Replaced more boilerplate SMB open code with calls to smb_open_sub().

Use the email_sec.js module if you want this feature.

when creating a new netmail message. Not exactly an "address book", but a
convenience nonetheless.
