JS modules (and the functions they execute) make use of the text.dat strings.

This means that the Baja TEXT_FILE_SECTION function and the JS bbs.text_sec()
method now execute the module rather than executing the old (now removed)
C++ code. Hooray!

JS) which will be executed when a users uses the the (L)ist msgs command from
the "Reading" sub or "Reading E-mail" prompt.
The arguments passed to the module are: <sub-code> [which]  [usernum]  [lm_mode]
The additional optional arguments are the same values as would be passed to a
readmail_mod, if one were to be used instead.

The scfg_t instances are often shared between threads and we can't really share
file descriptors between threads, so we ended up with file descriptor leaks and
race conditions.

Instead, define/allocate/free a new js_system_private_t where the scfg_t* and
the nodefile (descriptor) are kept - per "system" instance.

(ctrl/node.dab) is constantly closed and re-opened for every non-locking read.
This is really slow across network file systems and unnecessary, so use a
similar optimization as the C++ sbbs_t class where the file can (and normally
is) left open across multiple consecutive reads.

support in putmsg/printfile, etc. on per-use basis.
Add per-sub-board P-mode flags (so "Extra Attribute Codes" can be disabled

- 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).

For QuickBBS editors, the default will be the same as previous behavior: to
convert Soft-CRs to Hard-CRs (CRLFs).
For non-QuickBBS editors, the default will be to treat Soft-CRs as any other
valid printable character in the text ("Retain").
A 3rd option is available to strip Soft-CRs completely from the generated
message text.

terminal width) - only used when the QUOTEWRAP option is set. Common values:
0 - current behavior, wrap the quote file to the current terminal width
80 - wrap 80 columns specifically (actually, 79)
9999 - unwrap to long lines (one line per paragraph)

Actually, previously it was wrapping to current terminal width minus 4 when
QUOTEWRAP was enabled. Now, make that current terminal width minus 1
(when quotewrap_cols is set to 0).

network hub call-outs and timed-events.

It's destroyed in free_scfg(), and the config *must* be prepped both to
destroy the certificate and to load it.  This is because the "no cert"
value is -1, not 0, so the prepped flag is all we really have to indicate
if it's zero because it's a valid certificate or zero because no certificate
has been loaded.

than non-SPAM-tagged email.

  Automatically detect child sub-directories and make them available as virtual
  directories for users to download from - only useful via FTP currently.
* Implemented Sorting options for Message Groups and File Libraries:
  Sub-boards within groups and directories within library can now be
  automatically sorted based on the sysop's chosen sort field (long name, short
  name, or internal code)
  - Required that sub-boards are now stored/saved in msgs.cnf based on groups
  - Required QWKnet hub sub-board reference dynamic renumbering
* Implemented "Template" toggle option for sub-boards and file directories:
  A sub-board or directory marked as "template" will be used for newly created
  (or imported) subs/dirs for that group/lib. Clone Options via SCFG will now
  use the "template" item as the source of the cloned settings, if available.

- Include Kludge Lines     (Yes)
- Include VOTING.DAT File   (Yes)
- Include HEADERS.DAT File   (Yes)
- Extended (QWKE) Packets    (No)
- Exported Ctrl-A Codes    (Strip)

SBBS/QWKnet nodes now have more control over the REP packet files created
by their systems. If the "uplink" (hub) is complaining about receiving
unsupported files (e.g. VOTING.DAT) or kluge lines (e.g. @TZ), just turn them
off.

Also, Ctrl-A codes may now be retained in QWKnetmail. And the @REPLYTO kludge
line enabled for the first time (!).

no longer uses it (as of v3).

messages), you can now set the Guest accounts new-msg-scan values. The default
is 0 (no new messages).
Using a value of 0 for this or the New User Days of Messages value results in a
very fast message pointer initialization (no "Loading Message Pointers..."
delay).

Sysop can set the number of days-worth of new messages that new users will
see in their first new-message scan (the default is 0, no new messages).
This does lengthen the amount of time that the first "Loading message pointers"
is displayed (it has to go and open all the message bases), but at least new
users are no longer bombarded with thousands of very old messages when they
answer "Yes" to the "Scan for New Messages" prompt. This setting is in
SCFG->System->New User Values->Days of New Messages. Set it to some really
high number (maximum of 9999) if you want the old behavior.

Optionally, external modules may be executed in place of "built-in" operations
for:
- reading mail (email or netmail)
- scanning posts (searching/scanning/reading a single sub-board)
- scanning sub-boards (all, one, or a group)

Each of these may be configured (in SCFG->System->Loadable Modules)
with command-line options for a total length of up to 63 characters.

Note to module programmers: each module here will be passed additional
command-line arguments to indicate how or why the user operation was invoked.

For the Reading Mail module, the 'which' value (in decimal) and the user-number
is passed (in decimal). Usually the user-number will be the current user logged
in, but not always (e.g. if the user is a sysop and reading other user's mail).
The 'which' values (defined in load/sbbsdefs.js) of MAIL_YOUR, MAIL_SENT,
and MAIL_ALL must be handled (MAIL_ANY won't be used).

For the Scan Posts module, the sub-board number and scan mode (both in decimal)
and the 'find' string (text being searched for) are passed as arguments
(in that order). The scan mode values (defined in sbbsdefs.js) are the same as
those supported by bbs.scan_posts(). All of the values should be supported
and they can be combined (e.g. SCAN_CONST|SCAN_NEW
and SCAN_NEW|SCAN_TOYOU). The 'find' string is only used if the SCAN_FIND mode
bit is set. It is the responsibilty of the module (if configured) to enforce
sub-board read access restrictions.

For the Scan Subs module, the first argument is 1 if "all subs" are being
scanned, 0 otherwise (normally the user is prompted for the breadth of the
scan in this case, but that's up to the module author), and the scan 'mode' is
passed in decimal, in that order. If the SCAN_FIND mode flag is passed in, this
module should prompt the user for the text string to search for. If this module
is not configured, the Scan Posts module will be executed for each sub-board
scanned.

Recursion protection was added, so it is actually possible for the Read Mail
module, for example, to call bbs.read_mail() and it'll work, but why would you?

If any of these user operations are initiated during logon, at the request of
Baja or JavaScript module, or whatever, and if the module is actually
configured (and not already executing to handle the operation), the module
will be executed in-place-of the built-in functionality. Feedback welcome,
