libpayload: Add PDCurses and ncurses' libform/libmenu
PDCurses provides an alternative implementation of the curses library standard in addition to tinycurses. Where tinycurses is really tiny, PDCurses is more complete and provides virtually unlimited windows and the full API. The PDCurses code is brought in "vanilla", with all local changes residing in curses/pdcurses-backend/ In addition to a curses library, this change also provides libpanel (as part of the PDCurses code), and libform and libmenu which were derived from ncurses-5.9. As they rely on ncurses internals (and PDCurses is not ncurses), more changes were required for these libraries to work. The build system is extended to install the right set of header files depending on the selected curses implementation.

+ Name: bkgd
+
+ Synopsis:
+ int bkgd(chtype ch);
+ void bkgdset(chtype ch);
+ chtype getbkgd(WINDOW *win);
+ int wbkgd(WINDOW *win, chtype ch);
+ void wbkgdset(WINDOW *win, chtype ch);
+
+ int bkgrnd(const cchar_t *wch);
+ void bkgrndset(const cchar_t *wch);
+ int getbkgrnd(cchar_t *wch);
+ int wbkgrnd(WINDOW *win, const cchar_t *wch);
+ void wbkgrndset(WINDOW *win, const cchar_t *wch);
+ int wgetbkgrnd(WINDOW *win, cchar_t *wch);
+
+ Description:
+ bkgdset() and wbkgdset() manipulate the background of a window.
+ The background is a chtype consisting of any combination of
+ attributes and a character; it is combined with each chtype
+ added or inserted to the window by waddch() or winsch(). Only
+ the attribute part is used to set the background of non-blank
+ characters, while both character and attributes are used for
+ blank positions.
+
+ bkgd() and wbkgd() not only change the background, but apply it
+ immediately to every cell in the window.
+
+ The attributes that are defined with the attrset()/attron() set
+ of functions take precedence over the background attributes if
+ there is a conflict (e.g., different color pairs).
+
+ Return Value:
+ bkgd() and wbkgd() return OK, unless the window is NULL, in
+ which case they return ERR.
