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.

Also remove tbl files from CLEANFILES now they are not generated.

Remove obsolete tbl suffix from ncurses man pages, no objections from
millert.

remove misc. depend and yacc nits that no longer matter.
okay millert@

mark files as BUILDFIRST, or write explicit dependencies, so that most
programs will build even without a make depend first.
okay tb@ millert@

Include the legacy_coding(3) page which documents use_legacy_coding(),
probably missed at one update or another. Reported by Anthony Coulter,
discussed with jmc.

DEBUGLIBS has been broken since the gcc4 switch, so delete it. CFLAGS
contains -g by default anyway

for some time now mandoc has not required MLINKS to function
correctly - logically complete that now by removing MLINKS from base;

authors need only to ensure there is an entry in NAME for any function/
util being added. MLINKS will still work, and remain for perl to ease
upgrades;

Instead of using our own custom BDB terminfo databases, use the ncurses
files in /usr/share/terminfo/*. This removes a large difference from
upstream ncurses and other systems.

the tparam mlink is probably a typo (and duplicate) for tparm, so kill it;

to the bit bucket sometime soon)

Enable wide character support in ncurses. It is built into libcurses,
libform, libmenu, libpanel and each library is also linked to a
corresponding "w" version.

This is a major bump for all four libraries.

else I've forgotten for testing.

Add the generated files as a dependency for the 'all' target.
Should prevent bogus bug reports that come in every so often...

Add a link to libncurses. Lots of programs/configure scripts out there
look for ncurses by checking for ncurses.h or libncurses instead of
checking for NCURSES_VERSION in curses.h. Closes PR 2942.
