Update ncurses and associated libraries (form, panel, menu) to

6.4-20230826 (from 5.7-20081102).

Based on result from Thomas Dickey's ncu2openbsd script and then
modified. Switches to the upstream tput. Major bump for the ncurses
libraries and for libedit and libreadline.

Help from tb, millert.

+.SH PORTABILITY
+The panel facility was documented in SVr4.2 in
+\fICharacter User Interface Programming (UNIX SVR4.2)\fP.
+.PP
+It is not part of X/Open Curses.
+.PP
+A few implementations exist:
+.bP
+Systems based on SVr4 source code,
+e.g., Solaris, provide this library.
+.bP
+\fBncurses\fP (since version 0.6 in 1993)
+and \fBPDCurses\fP (since version 2.2 in 1995)
+provide a panel library whose common ancestor
+was a public domain implementation by Warren Tucker
+published in \fIu386mon\fP 2.20 (1990).
+.IP
+According to Tucker, the SystemV panel library
+was first released in SVr3.2 (1988),
+and his implementation helped with a port to SVr3.1 (1987).
+.IP
+Several developers have improved each of these;
+they are no longer the same as Tucker's implementation.
+.bP
+NetBSD 8 (2018)
+has a panel library begun by Valery Ushakov in 2015.
+This is based on the AT&T documentation.
