kconfig: sort found symbols by relevance
When searching for symbols, return the symbols sorted by relevance. Sorting is done as thus: - first, symbols that match exactly - then, alphabetical sort Since the search can be a regexp, it is possible that more than one symbol matches exactly. In this case, we can't decide which to sort first, so we fallback to alphabeticall sort. Explain this (new!) sorting heuristic in the documentation.

+ When searching, symbols are sorted thus:
+ - exact match first: an exact match is when the search matches
+ the complete symbol name;
+ - alphabetical order: when two symbols do not match exactly,
+ they are sorted in alphabetical order (in the user's current
+ locale).
+ For example: ^ATH.K matches:
+ ATH5K ATH9K ATH5K_AHB ATH5K_DEBUG [...] ATH6KL ATH6KL_DEBUG
+ [...] ATH9K_AHB ATH9K_BTCOEX_SUPPORT ATH9K_COMMON [...]
+ of which only ATH5K and ATH9K match exactly and so are sorted
+ first (and in alphabetical order), then come all other symbols,
+ sorted in alphabetical order.
