SearchAbout and similar: add a customizable blacklist

 Instead of hard-coding in search.ml some substrings such
 as "_admitted" or "_subproof" we don't want to see in results
 of SearchAbout and co, we now have a user command:

  Add Search Blacklist "foo".
  Remove Search Blacklist "foo". (* the opposite *)
  Print Table Search Blacklist. (* the current state *)

 In Prelude.v, three substrings are blacklisted originally:
  - "_admitted" for internal lemmas due to admit.
  - "_subproof" for internal lemmas due to abstract.
  - "Private_" for hiding auxiliary modules not meant for
    global usage.

 Note that substrings are searched in the fully qualified names
 of the available lemmas (e.g. "Coq.Init.Peano.plus").

 This commit also adds the prefix "Private_" to some internal modules
 in Numbers, Z, N, etc.
