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:                                                         insch
+
+  Synopsis:
+        int insch(chtype ch);
+        int winsch(WINDOW *win, chtype ch);
+        int mvinsch(int y, int x, chtype ch);
+        int mvwinsch(WINDOW *win, int y, int x, chtype ch);
+
+        int insrawch(chtype ch);
+        int winsrawch(WINDOW *win, chtype ch);
+        int mvinsrawch(int y, int x, chtype ch);
+        int mvwinsrawch(WINDOW *win, int y, int x, chtype ch);
+
+        int ins_wch(const cchar_t *wch);
+        int wins_wch(WINDOW *win, const cchar_t *wch);
+        int mvins_wch(int y, int x, const cchar_t *wch);
+        int mvwins_wch(WINDOW *win, int y, int x, const cchar_t *wch);
+
+  Description:
+        The insch() functions insert a chtype into the window at the 
+        current or specified cursor position. The cursor is NOT 
+        advanced. A newline is equivalent to clrtoeol(); tabs are 
+        expanded; other control characters are converted as with 
+        unctrl().
+
+        The ins_wch() functions are the wide-character
+        equivalents, taking cchar_t pointers rather than chtypes.
+
+        Video attributes can be combined with a character by ORing
+        them into the parameter. Text, including attributes, can be 
+        copied from one place to another using inch() and insch().
+
+        insrawch() etc. are PDCurses-specific wrappers for insch() etc. 
+        that disable the translation of control characters.
+
+  Return Value:
+        All functions return OK on success and ERR on error.
