Paul Menzel bab0a0b577 PDCurses: pdcscrn.c: Use `#ifdef` instead of `#if CONFIG_SPEAKER`
Building libpayload with the PDCurses backend the following warning
is shown.

    /src/coreboot/payloads/libpayload(master) $ make clean
    /src/coreboot/payloads/libpayload(master) $ make

    curses/pdcurses-backend/pdcscrn.c: In function 'PDC_scr_open':
    curses/pdcurses-backend/pdcscrn.c:75:5: warning: "CONFIG_SPEAKER" is not defined [-Wundef]
    […]

The GCC documentation states [1]

    In some contexts this shortcut is undesirable. The -Wundef option
    causes GCC to warn whenever it encounters an identifier which is
    not a macro in an ‘#if’.

and therefore use `#ifdef` [2] to silence this warning. No functional
change is done, as `CONFIG_SPEAKER` is assigned the value `Y` when
defined.

There was some discussion going on the list [3], but my points in there
turned out to be incorrect.

Patrick Georgi 3b77b723ca 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.
