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: initscr
+
+ Synopsis:
+ WINDOW *initscr(void);
+ WINDOW *Xinitscr(int argc, char *argv[]);
+ int endwin(void);
+ bool isendwin(void);
+ SCREEN *newterm(const char *type, FILE *outfd, FILE *infd);
+ SCREEN *set_term(SCREEN *new);
+ void delscreen(SCREEN *sp);
+
+ int resize_term(int nlines, int ncols);
+ bool is_termresized(void);
+ const char *curses_version(void);
+
+ Description:
+ initscr() should be the first curses routine called. It will
+ initialize all curses data structures, and arrange that the
+ first call to refresh() will clear the screen. In case of
+ error, initscr() will write a message to standard error and end
+ the program.
+
+ endwin() should be called before exiting or escaping from curses
+ mode temporarily. It will restore tty modes, move the cursor to
+ the lower left corner of the screen and reset the terminal into
+ the proper non-visual mode. To resume curses after a temporary
+ escape, call refresh() or doupdate().
+
+ isendwin() returns TRUE if endwin() has been called without a
+ subsequent refresh, unless SP is NULL.
+
+ In some implementations of curses, newterm() allows the use of
+ multiple terminals. Here, it's just an alternative interface for
+ initscr(). It always returns SP, or NULL.
+
+ delscreen() frees the memory allocated by newterm() or
+ initscr(), since it's not freed by endwin(). This function is
+ usually not needed. In PDCurses, the parameter must be the
+ value of SP, and delscreen() sets SP to NULL.
+
+ set_term() does nothing meaningful in PDCurses, but is included
+ for compatibility with other curses implementations.
+
+ resize_term() is effectively two functions: When called with
+ nonzero values for nlines and ncols, it attempts to resize the
+ screen to the given size. When called with (0, 0), it merely
+ adjusts the internal structures to match the current size after
+ the screen is resized by the user. On the currently supported
+ platforms, this functionality is mutually exclusive: X11 allows
+ user resizing, while DOS, OS/2 and Win32 allow programmatic
+ resizing. If you want to support user resizing, you should check
+ for getch() returning KEY_RESIZE, and/or call is_termresized()
+ at appropriate times; if either condition occurs, call
+ resize_term(0, 0). Then, with either user or programmatic
+ resizing, you'll have to resize any windows you've created, as
+ appropriate; resize_term() only handles stdscr and curscr.
+
+ is_termresized() returns TRUE if the curses screen has been
+ resized by the user, and a call to resize_term() is needed.
+ Checking for KEY_RESIZE is generally preferable, unless you're
+ not handling the keyboard.
+
+ curses_version() returns a string describing the version of
+ PDCurses.
+
+ Return Value:
+ All functions return NULL on error, except endwin(), which
+ returns ERR on error.
