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.

 The initscr code determines the terminal type and initializes all \fBcurses\fR

 A program should always call \fBendwin\fR before exiting or escaping from
 \fBcurses\fR mode temporarily.  This routine restores tty modes, moves the
 cursor to the lower left-hand corner of the screen and resets the terminal into
 the proper non-visual mode.  Calling \fBrefresh\fR or \fBdoupdate\fR after a
 temporary escape causes the program to resume visual mode.

 .SH NOTES
 Note that \fBinitscr\fR and \fBnewterm\fR may be macros.
 .SH PORTABILITY
 These functions are described in the XSI Curses standard, Issue 4.  It
 specifies that portable applications must not call \fBinitscr\fR more than
 once.

 Old versions of curses, e.g., BSD 4.4, may have returned a null pointer
 from \fBinitscr\fR when an error is detected, rather than exiting.
