This requires anything that includes sbbs.h to have cryptlib and
mozjs already built/isntalled... to track this, I've added the new
extdeps.mk file.

This is pretty terrible though... not sure how important that
dependency really is.

This fixes the stat() issue on Windows XP/2K3 by allowing sbbs to benefit
from the run-time library updates that Microsoft releases periodically
(like https://www.microsoft.com/en-us/download/details.aspx?id=53840).

For more info on the stat() issue which caused all kinds of sbbs errors
(e.g. creating directories initially, but a lot more):

Since we are using cryptlib which requires the MSVC runtime DLL anyway
(it is the default build behavior of MSVC), we weren't really gaining
anything from statically linking the CRTL (LIBCMT.LIB). And for some reason,
an up-to-date MSVC2019 still has (links-in) a LIBCMT.LIB file that includes
this stat bug. All the online help resources I found just to seem to suggest
updating the CRTL DLLs (on the target system), with no mention of any fixes
available for the static CRTLs on the build system. But with the no gain
from static linking anyway, I figured it was time to switch to DLL CRTLs.

The debug builds are still statically linking the CRTL for no particular
reason.

There are a number of conio changes in here too... too many to list.  Check
the diffs if you actually want to know what changed.

getcliptext() and copytext() (ie: copy/paste) now work on UTF-8 strings.
Not tested on Win32 yet.

There still another crash I'm investigating that occurs if you type a string
that isn't found. It appears to deref past the end of the option array.

- 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.

characters as the buffer width terminated by a linefeed would cause an
extra blank line to be inserted due to incorrect end-of-line detection.

The number of lines to allocate was calculated correctly, so this resulted
in writing past the last line in the screen buffer, corrupting memory after
the allocation.  Glibc detected this condition and crashed with a double-
free or corruption message.

This allows full control over the display, and avoids font mangling.

Backspace (the "Delete" key on a MacBookPro keyboard) is treated the same
as ESC (exit).
Make the help status bar more clear in Mac OS X builds that the '+' key
may be used in place of the INSert key to add itesm and that fn-DELete key
sequence is used to delete items (or the '-' key, though that isn't stated).

treat the same Delete Char. This is for systems were there is no "Delete Char"
key (e.g. Mac) or where the Delete and Backspace keys send the reverse key
codes. On a Mac, the Backspace key is actually labeled "Delete", so treat
the key-code sent as "Delete item", consistent with the status bar/help
indicator.

never maintened or used since. So... remove from CVS.
