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: kernel
+
+ Synopsis:
+ int def_prog_mode(void);
+ int def_shell_mode(void);
+ int reset_prog_mode(void);
+ int reset_shell_mode(void);
+ int resetty(void);
+ int savetty(void);
+ int ripoffline(int line, int (*init)(WINDOW *, int));
+ int curs_set(int visibility);
+ int napms(int ms);
+
+ int draino(int ms);
+ int resetterm(void);
+ int fixterm(void);
+ int saveterm(void);
+
+ Description:
+ def_prog_mode() and def_shell_mode() save the current terminal
+ modes as the "program" (in curses) or "shell" (not in curses)
+ state for use by the reset_prog_mode() and reset_shell_mode()
+ functions. This is done automatically by initscr().
+
+ reset_prog_mode() and reset_shell_mode() restore the terminal to
+ "program" (in curses) or "shell" (not in curses) state. These
+ are done automatically by endwin() and doupdate() after an
+ endwin(), so they would normally not be called before these
+ functions.
+
+ savetty() and resetty() save and restore the state of the
+ terminal modes. savetty() saves the current state in a buffer,
+ and resetty() restores the state to what it was at the last call
+ to savetty().
+
+ curs_set() alters the appearance of the cursor. A visibility of
+ 0 makes it disappear; 1 makes it appear "normal" (usually an
+ underline) and 2 makes it "highly visible" (usually a block).
+
+ ripoffline() reduces the size of stdscr by one line. If the
+ "line" parameter is positive, the line is removed from the top
+ of the screen; if negative, from the bottom. Up to 5 lines can
+ be ripped off stdscr by calling ripoffline() repeatedly. The
+ function argument, init, is called from within initscr() or
+ newterm(), so ripoffline() must be called before either of these
+ functions. The init function receives a pointer to a one-line
+ WINDOW, and the width of the window. Calling ripoffline() with a
+ NULL init function pointer is an error.
+
+ napms() suspends the program for the specified number of
+ milliseconds. draino() is an archaic equivalent.
+
+ resetterm(), fixterm() and saveterm() are archaic equivalents
+ for reset_shell_mode(), reset_prog_mode() and def_prog_mode(),
+ respectively.
+
+ Return Value:
+ All functions return OK on success and ERR on error, except
+ curs_set(), which returns the previous visibility.
