Fixes recently broken Win32 build

There are lot of places in the code where subnums and dirnums (especially) are compared against total_subs and/or total_dirs or >= 0 without a ton of consistency. We should migrate to use these functions for validity-checking going forward.

Just in case a sysop deletes/changes their addresses after create subs, find the nearest matching configured system FTN address/AKA and use that.

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...

We were just trusting that the error strings would be shorter than 256 (usually), but since we're including paths and strerror() results, we really have no control over the length of the error strings. So enforce some healthy boundaries. This could explain the crashes that Divarin of Mutiny is seeing with SCFG on WinXP or maybe it was the truncsp(strerror()) stuff that was just removed as well. We'll see...

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.

- for PETSCII, this is automatic and you don't lose blink, but you do lose
  colored foreground when enabling a bright background ("reverse video")
- for ANSI, this mode is typically referred to as "iCE colors" and disables
  blinking-text support
- Ctrl-AE (^AE) is the new attribute code to enable bright-background
  (will have no effect on ANSI terminals that are not iCE color enabled)
  "E" is now valid in the ctrl/attr.cfg file and string values for JS
  console.attributes assignments, as well
- Ctrl-AI (^AI) - blink - now does nothing for ANSI/ICE color terminals
  (blinking is not supported in combination with bright-background)
- Using a new/non-standard CGA attribute bit-flag to indicate the selection of
  bright-background colors (BG_BRIGHT, bit 10), separate from BLINK.
  This change required all/most char/uchar attribute representations to be
  converted to int/uint.

New text.dat strings:
- PetTerminalDetected (renamed from PetTermDetected)
- PetTerminalQ
- TerminalAutoDetect
- TerminalColumns
- TerminalRows
- TerminalMonochrome
- TerminalColor
- TerminalIceColor
- IceColorTerminalQ
This also moved the MsgCarbonCopyList definition to the end of the file
for now.

PETSCII reverse-video attribute fix:
When a CR is sent to the terminal, the reverse-video attibute is auto-disabled
so update our "current attribute" (curatr) value to match the remote.

Support new printfile/putmsg mode flag: P_WRAP to force an ungraceful
line-wrap (splitting) to the specified column width. If no column width is
specified (0), then this mode will force an ungraceful wrap before the last
terminal column where some terminals *may* auto-wrap.

JS console.printfile() and printtail() methods now support an optional
"orig_columns" argument, similar to console.putmsg(). Must specify P_WORDWRAP
or P_WRAP for this argument to have any effect.

Much improved terminal-type selection/configuration in the user defaults
menu and abort (^C) at any of the yes/no prompts is now detected/handled much
better (to answers to the prompted questions are not saved to the user
settings).

call to either lputs or eputs based on the node number (0 = event thread).
Created a sbbs_t::backup() wrapper for the C version which logs some helpful
debug output.
Backup the mail.hash and mail.ini file too.
Log the number of emails removed during daily maintenance.
DLL-export smb_open_sub() and smb_storage_mode() so they can be used in more
places.

"the right way", this will be used to replace a lot of copy/pasta over time.

mode for a specified message base (mail or sub-board). This logic exists in
many other files and can now be consolidated using this single function.

subject_crc() to smb_subject_crc().

compile AR strings for SCFG).

Added FREE_ALLOC macro (to free cfg buffers malloced with get_alloc).
Removed definition of SAVE_MEMORY (duplicate pointers make freeing difficult).

Renamed prep_path to prep_dir and created prep_path function to convert \ to / (Unix compatibility).

Created new make_data_dirs() function to create data directory and hard-coded sub-directories if they don't already exist.
