kconfig/menuconfig: distinguish between selected-by-another options and comments

Browse Source 
menuconfig currently represents options implied by another option ('select'
directive in Kconfig) by prefixing them with '---'.  Unfortunately the same
notation is used for comments.  If the implied option is module capable,
user can still switch between Y and M, all without any feedback until she
visits option's help.  (try saying M to MAC80211 and then toggling
CFG80211)

This patch changes notation of selected-by-another items by introducing 2
new representations for implied options: {*} or {M} for options selected by
another modularized one, thus builtin or module capable, -*- or -M- for
options that cannot be at the moment changed by user.

The idea is to represent actual capability of the option by braces (dashes)
around and to always report actual state by * or M inside.
