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:                                                         termattr
+
+  Synopsis:
+        int baudrate(void);
+        char erasechar(void);
+        bool has_ic(void);
+        bool has_il(void);
+        char killchar(void);
+        char *longname(void);
+        chtype termattrs(void);
+        attr_t term_attrs(void);
+        char *termname(void);
+
+        int erasewchar(wchar_t *ch);
+        int killwchar(wchar_t *ch);
+
+        char wordchar(void);
+
+  Description:
+        baudrate() is supposed to return the output speed of the 
+        terminal. In PDCurses, it simply returns INT_MAX.
+
+        has_ic and has_il() return TRUE. These functions have meaning in 
+        some other implementations of curses.
+
+        erasechar() and killchar() return ^H and ^U, respectively -- the 
+        ERASE and KILL characters. In other curses implementations, 
+        these may vary by terminal type. erasewchar() and killwchar() 
+        are the wide-character versions; they take a pointer to a 
+        location in which to store the character, and return OK or ERR.
+
+        longname() returns a pointer to a static area containing a
+        verbose description of the current terminal. The maximum length
+        of the string is 128 characters.  It is defined only after the
+        call to initscr() or newterm().
+
+        termname() returns a pointer to a static area containing a
+        short description of the current terminal (14 characters).
+
+        termattrs() returns a logical OR of all video attributes
+        supported by the terminal.
+
+        wordchar() is a PDCurses extension of the concept behind the 
+        functions erasechar() and killchar(), returning the "delete 
+        word" character, ^W.
