Submenus are sometimes empty and it would be nice if there is
something that notifies us that we should not expect any content
_before_ we enter a submenu.

A new function menu_is_empty() was introduced and empty menus and
menuconfigs are now marked by "----" as opposed to non-empty ones that
are marked by "--->".

This scheme was suggested by "Yann E. MORIN" <yann.morin.1998@free.fr>.

When exiting menuconfig with unsaved changes, a dialog like
the following is shown:

        Do you wish to save your new configuration ? <ESC><ESC>
        to continue.

The author of the dialog text specified a newline after the '?',
and probably expected it to be processed, so let print_autowrap()
handle newlines propperly.

Also, reword that dialog's second phrase with a real sentence.

Yann had some more ideas on improvements:

"What would be nice is an improvement that scales the choice window to
the number of entries in the choice. If there are a lot of choice
entries, then the choice popup grows in height (but does not overflow
the screen of course). So, instead of seeing only 6 entries, we'd see
as much as possible in the current screen.

Ditto for the width: the popup adapts to the longest prompt (but does
not overflow the screen either, of course), so prompts are not
truncated."

NOTE: This patch requires [1].

When entering an empty dialog, using the movement keys resulted in
unexpected characters beeing displayed, other keys like "z" and "h"
did not work as expected.

Hardware with MCA bus is limited to 386 and 486 class machines
that are now 20+ years old and typically with less than 32MB
of memory.  A quick search on the internet, and you see that
even the MCA hobbyist/enthusiast community has lost interest
in the early 2000 era and never really even moved ahead from
the 2.4 kernels to the 2.6 series.

This deletes anything remaining related to CONFIG_MCA from core
kernel code and from the x86 architecture.  There is no point in
carrying this any further into the future.

One complication to watch for is inadvertently scooping up
stuff relating to machine check, since there is overlap in
the TLA name space (e.g. arch/x86/boot/mca.c).

Usage:
  Press <Z> to show all config symbols which have prompts.

Quote Tim Bird:

| I've been bitten by this numerous times.  I most often
| use ftrace on ARM, but when I go back to x86, I almost
| always go through a sequence of searching for the
| function graph tracer in the menus, then realizing it's
| completely missing until I disable CC_OPTIMIZE_FOR_SIZE.
|
| Is there any way to have the menu item appear, but be
| unsettable unless the SIZE option is disabled?  I'm
| not a Kconfig guru...

I myself found this useful too. For example, I need to test
ftrace/tracing and want to be sure all the tracing features are
enabled, so I  enter the "Tracers" menu, and press <Z> to
see if there is any config hidden.

I also noticed gconfig and xconfig have a button "Show all options",
but that's a bit too much, and I think normally what we are not
interested in those configs which have no prompt thus can't be
changed by users.

Exmaple:

      --- Tracers
      -*-   Kernel Function Tracer
      - -     Kernel Function Graph Tracer
      [*]   Interrupts-off Latency Tracer
      - -   Preemption-off Latency Tracer
      [*]   Sysprof Tracer

Here you can see 2 tracers are not selectable, and then can find
out how to make them selectable.

This patch was inspired by the kernel projects page, where an ncurses
replacement for menuconfig was mentioned (by Sam Ravnborg).

Building on menuconfig, this patch implements a more modern look
interface using ncurses and ncurses' satellite libraries (menu, panel,
form). The implementation does not depend on lxdialog, which is
currently distributed with the kernel.

Help text for certain config options is very extensive (the text
includes the names of all  other options the option in question depends
on). Long lines are not wrapped, making it impossible to see the list
without scrolling horizontally.

This patch adds some logic which wraps help screen lines at word
boundaries to prevent truncating.

Tested by running

  ARCH=powerpc make menuconfig O=/tmp/build

which shows that the long lines are now wrapped, and

 ARCH=powerpc make xconfig O=/tmp/build

to demonstrate that it still compiles and operates as expected.

Kconfig is powerfull tool. So powerfull that more and more software
projects are using it for configuration. So instead of fixing some of
them one by one, lets fix it in kernel and wait for sync.

This work was originaly done for PTXdist - GPL licensed build system for
userlands and cross-compilers, but it will not hurt kernel kconfig
either. PTXdist menuconfig now works on Windows linked with PDCurses and
compiled using MinGW - there is no termios and signals.

* Do not include <sys/wait.h> and <signal.h> (comes from times when
  lxdialog was separate process)
* Do not mess with termios directly and let curses tell screen size.
  Comment to commit c8dc68ad says
  check for screen size could be removed later, but because it didn't
  happen for more than year I left it here as well.
