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).

nconf does not check the validity of the current menu when help is
requested (with either <F2>, '?' or 'h'). This leads to a NULL pointer
dereference when an empty menu is encountered.

The following reduced testcase exposes the problem:

config DEP
        bool

menu "FOO"

config BAR
        bool "BAR"
        depends on DEP

endmenu

Issue will happen when entering menu "FOO" and requesting help.

nconf is the only front-end which do not filter the validity of the
current menu. Such filter can not really happen beforehand as other key
which does not deals with the current menu might be entered by the user,
so just bails out earlier if we encounter an invalid menu.

nconf is the only front-end which does not use this helper, but prefer
to copy/paste the code. The test wrt. menu validity added in this
version of the code is bogus anyway as an invalid menu will get
dereferenced a few line below by calling menu_get_prompt().

For now, convert nconf to use menu_get_ext_help(), as do every other
front-end. We will deals with menu validity checks properly in a
separate commit.

When getting the help for a choice menu with a help section (for example
the "Choose SLAB allocator" menu) nconfig pops up a window with nothing
inside it. This is due to show_help() passing an empty string to
show_scroll_win()'s 3rd argument. The option really does have help
though, but it isn't a config symbol, so just add the help text for
the option, and don't try to add anything else like the config option
name.

Remove the old hotkeys feature, and replace it by an interactive string
search.
From nconfig help:

Searching: pressing '/' triggers interactive search mode.
           nconfig performs a case insensitive search for the string
           in the menu prompts (no regex support).
           Pressing the up/down keys highlights the previous/next
           matching item. Backspace removes one character from the
           match string. Pressing either '/' again or ESC exits
           search mode. All other keys behave normally.

Miscellaneous other changes (including Rundy's and Justin's input).

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.
