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:                                                         clipboard
+
+  Synopsis:
+        int PDC_getclipboard(char **contents, long *length);
+        int PDC_setclipboard(const char *contents, long length);
+        int PDC_freeclipboard(char *contents);
+        int PDC_clearclipboard(void);
+
+  Description:
+        PDC_getclipboard() gets the textual contents of the system's 
+        clipboard. This function returns the contents of the clipboard 
+        in the contents argument. It is the responsibilitiy of the 
+        caller to free the memory returned, via PDC_freeclipboard().
+        The length of the clipboard contents is returned in the length 
+        argument.
+
+        PDC_setclipboard copies the supplied text into the system's 
+        clipboard, emptying the clipboard prior to the copy.
+
+        PDC_clearclipboard() clears the internal clipboard.
+
+  Return Values:
+        indicator of success/failure of call.
+        PDC_CLIP_SUCCESS        the call was successful
+        PDC_CLIP_MEMORY_ERROR   unable to allocate sufficient memory for 
+                                the clipboard contents
+        PDC_CLIP_EMPTY          the clipboard contains no text
+        PDC_CLIP_ACCESS_ERROR   no clipboard support
