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.

int mvgetnstr(int y, int x, char *str, int n);
int mvwgetnstr(WINDOW *win, int y, int x, char *str, int n);
int get_wstr(wint_t *wstr);
int wget_wstr(WINDOW *win, wint_t *wstr);
int mvget_wstr(int y, int x, wint_t *wstr);
int mvwget_wstr(WINDOW *win, int, int, wint_t *wstr);
int getn_wstr(wint_t *wstr, int n);
int wgetn_wstr(WINDOW *win, wint_t *wstr, int n);
int mvgetn_wstr(int y, int x, wint_t *wstr, int n);
int mvwgetn_wstr(WINDOW *win, int y, int x, wint_t *wstr, int n);
Description:
These routines call wgetch() repeatedly to build a string,
interpreting erase and kill characters along the way, until a
newline or carriage return is received. When PDCurses is built
with wide-character support enabled, the narrow-character
functions convert the wgetch()'d values into a multibyte string
in the current locale before returning it. The resulting string
is placed in the area pointed to by *str. The routines with n as
the last argument read at most n characters.
Note that there's no way to know how long the buffer passed to
wgetstr() is, so use wgetnstr() to avoid buffer overflows.
Return Value:
This functions return ERR on failure or any other value on
success.
