Prelude : no more autoload of plugins extraction and recdef

 The user now has to manually load them, respectively via:
   Require Extraction
   Require Import FunInd

 The "Import" in the case of FunInd is to ensure that the
 tactics functional induction and functional inversion are indeed
 in scope.

 Note that the Recdef.v file is still there as well (it contains
 complements used when doing Function with measures), and it also
 triggers a load of FunInd.v.

 This change is correctly documented in the refman, and the test-suite
 has been adapted.
