The struct list_head is often embedded in other structures, while other
code is used in C functions.

By separating struct list_head into its own header, other headers are no
longer required to include the entire list.h.

This is similar to the kernel space, where struct list_head is defined
in <linux/types.h> instead of <linux/list.h>.

You do not need to remember the index of each jump key because you can
count it up after a key is pressed.

Commit 95ac9b3b585d ("menuconfig: Assign jump keys per-page instead
of globally") injected a lot of hacks to the bottom of the textbox
infrastructure.

I reverted many of them without changing the behavior. (almost)
Now, the key markers are inserted when constructing the search result
instead of updating the text buffer on-the-fly.

The buffer passed to the textbox got back to a constant string.
The ugly casts from (const char *) to (char *) went away.

A disadvantage is that the same key numbers might be displayed multiple
times in the dialog if you use a huge window (but I believe it is
unlikely to happen).

The (void *) cast is redundant because the last argument of
show_textbox_ext() is an opaque pointer.

update_text() apparently edits the buffer returned by str_get().
(and there is no reason why it shouldn't)

Remove 'const' quailifier and casting.
