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.

 If \fIch\fR is any control character other than tab, newline, or backspace, it
 is drawn in \fB^\fR\fIX\fR notation.  Calling \fBwinch\fR after adding a
 control character does not return the character itself, but instead returns
 the ^-representation of the control character.

 Video attributes can be combined with a character argument passed to
 \fBaddch\fR or related functions by logical-ORing them into the character.
 (Thus, text, including attributes, can be copied from one place to another
 using \fBinch\fR and \fBaddch\fR.)  See the \fBcurs_attr\fR(3) page for
 values of predefined video attribute constants that can be usefully OR'ed
 into characters.
