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.

When system calls indicate an error they return -1, not some arbitrary
value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

exit() after perror() for pledge failure. Perhaps this got introduced
as a test idiom, either when pledge was young or during the transition
to strings.... dunno

pledge "stdio rpath wpath cpath". as a curses program, I expected this
to maybe need "tty", but have not found a path which calls those kind
of curses functions.

Update to ncurses 5.7, with local changes reapplied.

This is around eight years worth of changes (previously we were around ncurses
5.2), too many to list - many bug fixes and also a few new functions.

A major bump for libcurses, libpanel, libform and libmenu.

fgets(3) returns NULL on error, not 0. No functional change, but it makes
the code easier to read.

strdup check missing; noted by nimadeus@pandora.be

bump randomness of mktemp to from 6 to 10 X's, as recommended by mktemp(3)

spring cleaning; ok millert

Update to ncurses-5.2-20010210:
o remove macro callPutChar() from tty_update.c, since this is no longer
needed (reported by Philippe Blain).
o add a null-pointer check in tic.c to handle the case when the input
file is really empty. Modify the next_char() function in comp_scan.c
to allow arbitrarily long lines, and incidentally supply a newline to
files that do not end in a newline. These changes improve tic's
recovery from attempts to read binary files, e.g., its output from
the terminfo database (reported by Bernhard Rosenkraenzer).
o revert change to c++/demo.cc from 20001209, which changed definition
of main() apparently to accommodate cygwin linker, but broke the demo
program.

Update to ncurses-5.0-20000115:
+ additional fixes for non-bce terminals (handling of delete_character)
to work when assume_default_colors() is not specified.
+ modify warning message from _nc_parse_entry() regarding extended
capability names to print only if tic/infocmp/toe have the -v flag
set, and not at all in ordinary user applications. Otherwise, this
warning would be shown for screen's extended capabilities in programs
that use the termcap interface.
+ modify use of _nc_tracing from programs such as tic so their debug
level is not in the same range as values set by trace() function.
+ small panel header cleanup (patch by Juergen Pfeifer).

usage() should go to stderr, not stdout.

Update to ncurses-19991211:
o treat as untranslatable to termcap those terminfo strings which
contain non-decimal formatting, e.g., hexadecimal or octal.
o correct commented-out capabilities that cannot be translated to
termcap, which did not check if a colon must be escaped.
o correct termcap translation for "%>" and "%+", which did not check
if a colon must be escaped, for instance.
o use save_string/save_char for _nc_captoinfo() to eliminate fixed
buffer (originally for _nc_infotocap() in 960301 -TD).
o correct expression used for terminfo equivalent of termcap %B,
adjust regent100 entry which uses this.
o some cleanup and commenting of ad hoc cases in _nc_infotocap().
o eliminate a fixed-buffer in tic, used for translating comments.
o add manpage for infotocap.
