... and USERS.SYS file creation using new C++ type definitions in pcbdefs.hpp.

This mostly fixes issue #366.

PCBOARD.SYS is officially the worst file format ever invented, not just the worst BBS drop file format ever invented. What were these guys smoking?!?

I don't know what reference I used almost 30 years ago when I first implemented PCBOARD.SYS file support, but this time I used the PCBoard v15.3 source code (e.g. sys.c and usersys.c) and even their own code seems to work really hard to conform to these crazy file formats.

USERS.SYS is a little more sane, but not by a lot.

C++ features make this cleaner/easier, but man... there's just so much polish you apply to these turds.

I guess (and hope) that nobody's really running programs that depend on/use these file formats. <shrug>

Also displays net and aux attribute values when non-zero (weren't displayed
at all with the 'r'ead command previously).

Functionality replaced with Pascal::String

For Trikester (DOVEMOD/BSMNTQQ) 

A visual clue that there was a new navigation method available on some menus (where left/right arrow keys cycle through configured item) was needed. This seems to work nicely.

Similar to how we can now cycle through the file areas and message areas using left and right arrow keys, do the same for external "online" program sections and program (door) configurations.

Ah, that's better. Actually would work correctly on big-endian platforms (should we ever support one) and with way less code.

So I did a search through the code for sizeof.*long and was surprised to find some remaining (harmless) assumptions that a long is 32-bit.

So I was working on re-writing some of this door file generation code and noticed that the EXITINFO.BBS files generated by SBBS:

1. had a lot of garbage data filling unused string characters (no "harm", but potentially leaking information)
2. had the wrong total file length due to 64-bit logontime (time_t)
3. had the wrong total file length due to writing 19 GosubData elements (instead of 20)

The first and last issues appear to be some of those "forever" (20+ year old) bugs.

So I'm guessing no regularly used door games actually use these portions of the EXITINFO.BBS, so most likely: no harm, no foul. But still, best to fix this before I commit the rewrite.

p (which is used after this) points into 'str', so we can't use 'str' as a temporary variable here.

Nelgin's suggestion to support quick searching/scanning through message and file areas (e.g. comparing settings or whatever) without having to ESC then arrow key, ENTER, for each.

Uses Deuce's WIN_EXTKEYS UIFC mode flag, which I don't think I've used before now and uses the special -CIO_KEY value - 2 trick.

Also expanded the width of the sub-board and directory info windows to show more information (including full long name).

Fixes issue (wishlist item) #349 by Nelgin

As Andre pointed out, these checks perform no function because a user with a level lower than the user being edited cannot enter the related command-key anyway.

This was just effectively dead code that was held-over from ancient SBBS days, seemingly before I learned to effectively use the || operator:
if(!(atoi(str)>useron.level && console&CON_R_INPUT))

:-)

Fixes issue #361

At least, I think this fixes it.

At the suggestion/request of Andre Robitaille.

This option was originally added for debugging use, but may as well move it if it's useful in another way.

This only works on little endian systems (which is all we support currently).

Fixes CID 174261: Wrong size argument

This binary drop file writing code is pretty terrible and inefficient, but I remember being really proud of it (supporting so many drop files). This really should be re-written to use structures and/or buffered file I/O.

e.g. CID 229593: Negative loop bound

Fix CID 33266: Negative loop bound

e.g. CID 33631: Unbounded source buffer

Triggered by CID 33630: Unbounded source buffer

Also reversed the order of newsgroup name and area-tag options for a sub-board.

Updated help text too to specify that sub's area-tag can be derived from newsgroup name, if one is specified.

So this started with addressing CID 174264: Big parameter passed by value (PASS_BY_VALUE), but then I fell down the constification rabbit hole. :-)

Fix CID 33244: Argument cannot be negative

CID 33245
