Return to panel.priv.h CVS log

Up to [local] / src / lib / libpanel

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.
