Fix "CSI ["

yesno() and noyes() methods:
We need to check the argument count before using the second (optional)
argument or else it has some garbage/left-over value from some previous JS
function call. And no, just increasing the argument count in the method table
isn't enough. :-(
Reported by echicken and DaiTengu, thanks!

Still no modkey support though... cioapi doesn't currently support getting
this information.

XTerm.  This is what the FreeBSD console supports as well, so there's a
chance this works in curses mode too.

Curses is the least likely since IIRC, the curses mouse thing is insane.

Moved some dbprintf() lines around a bit.

It would create 3 0-byte files (*.shd, *.sdt, *.sid), but more is actually
needed for a message base to be "created" (i.e. a call to smb_create()).
So, MsgBase.open() now uses smb_open_sub() rather than smb_open() to initialize
theSMB  status fields with the proper default values (based on the sysop
configuration) and calls smb_crate() if the header file is empty.
Yes, normally, SCFG creates message bases, but it shouldn't have to
(e.g. a fresh install on *nix, doesn't actually start with any files in
data/subs) and now that we have JavaScript-based message lister/readers, we
really needed this support.

- incomplete, it didn't account for the CLEAR @-code which is only handled here
- caused side-effects in that any Baja PRINT function call with a single line
  that contained any  ^A or @-codes would reset the console abort indication
  flag (SS_ABORT).
  Observed: hitting Ctrl-C at while executing the yesnobar.bin or noyesbar.bin
  would leave "Yes Yes No" on the console, for example.
  Solution: use the tos (top-of-screen) state before/after the call to ctrl_a()
  or show_atcode() to determine if the reset-abort hack should be applied.

"No" in yesno() and noyes(), unless the P_SAVEATR mode flag was specified
(which may be used for the old behavior).

a body.  Broken by HSTS enhancement.

There's a (small) possibility that the HSTS enhancement is now broken.

While the FastCGI read_wait_timeout function should never return
CGI_*_READY with CGI_PROCESS_TERMINATED, it looks like somehow on some
systems, there's an additional select() happening after the process is
done.

Explicitly track this, and try to prevent it.

now required.

Should fix the POST/GET hangs on the wiki once DigitalMan updates.

(SMTPREVERSEPATH a.k.a. "reverse_path") if it didn't already have one.
That's because smb_getmsghdr() will point the msg.reverse_path convenience
pointer to the from_net_addr if there was no explicit reverse-path (e.g. RFC822's
"return-path" header field). This could manifest itself in *any* change to a
message header via JS failing with an "illegal header length increase" error if
the added header field just happen to put the total header length over the
allocation threshold of the pre-existing msg header.

Fix: only model a msg header "reverse_path" property if the header field
actually existed (not based on the SMBLIB convenience pointer).
When the expand_fields option is used, the old behavior remains but expanded
headers cannot be written back to the base, so no harm there.

Reported by Coz in #synchronet from failed runs of scrubmsgs.js. Thanks!

Apparently some USENET articles are >= 1MB these days. Thanks Coz.

Treat \n the same as \r (next msg cmd)when reading msgs.

- don't indent keys
- separate sections with a blank line (to improve readability without idents)

A nice tip from Ragnarok (DOCKSUD)!

- msg() now returns an int (e.g. 0 for OK, non-zero otherwise)
- add msgf() a printf-style version of msg()
- add confirm() a printf-stle yes/no dialog (returns TRUE on "Yes"/default)
- add deny() a printf-style no/yes dialog (returns TRUE on "No"/default)
- add yesNoOpts to allow application to over-ride "Yes"/"No" strings.

files were external to the executable (to conserve that precious 640KB of RAM!)
Some more use of SAFEPRINTF for good mesaure.

Use the COPYRIGHT_NOTICE macro rather than the build year.

with iniReadFile() has one or more !include directives.
!include directives must be followed by a space now so we don't false-match

Win32 can no longer exit() and WinExec() itself with impunity.
