They function just like they do in less(1).
Also correct some discrepancy between the help text and the code wrt
function keys.

The original dialog_inputbox doesn't work with longer than prompt_width
strings, here fixed it in this way:
1) add variable cursor_form_win to record cursor of form_win,
keep its value always between [0, prompt_width-1];
reuse the original cursor_position as cursor of the string result,
use (cursor_position-cursor_form_win) as begin offset to show part of
the string in form_win;

To support unlimited length string config items;
No check for realloc return value keeps code simple, and to be
consistent with other existing unchecked malloc in kconfig.

In case KEY_BACKSPACE / KEY_DC to delete a char, it memmove only
(len-cursor_position+1) bytes;
the default case is to insert a char, it should also memmove exactly
(len-cursor_position+1) bytes;
the original use of (len+1) is wrong and may access following memory
that doesn't belong to result, may cause SegFault in theory;
case KEY_BACKSPACE:
if (cursor_position > 0) {
memmove(&result[cursor_position-1],
&result[cursor_position],
len-cursor_position+1);
cursor_position--;
}
break;
case KEY_DC:
if (cursor_position >= 0 && cursor_position < len) {
memmove(&result[cursor_position],
&result[cursor_position+1],
len-cursor_position+1);
}
break;
default:
if ((isgraph(res) || isspace(res)) &&
len-2 < result_len) {
/* insert the char at the proper position */
memmove(&result[cursor_position+1],
&result[cursor_position],
len-cursor_position+1);
result[cursor_position] = res;
cursor_position++;
}

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).

nconfig segfaults when help text contains the character '%'. For a quick
example, navigate to the kernel compression options and get the help for
bzip2. Doing so triggers a call to mvwprintw() with a string containing
'%' and no extra arguments to fill in the specifier's value. Fix this
case by printing the literal string retrieved from the kconfig.

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.
